Proteins

Parent Category: Biology
Proteins are the macromolecules coded in our DNA that function as a biocatalyst and build our body. Apart from Biological knowledge, there are spectacular concepts in the field of proteins. How does a protein produce a function, how do they interact, how did they evolve and how do protein mutations cause disease.
this is the process of photosynthesis...it all starts with the DNA,  the mRNA copies the genetic information from the DNA and makes a  strand of mRNA, this is then transported to the nucleus where the  tRNA combines with the mRNA to make codons (3 bases=1 codon) these  codons then go into a...
Coca Cola dissolve the calcium on the chicken bone.
3.4=(32/y) * 100 --------> y=941.176g so, the least molecular  weight of insulin is 941.176g
The importance of this is to regulate the macromolecules in and out of membranesThe channel proteins and carrier proteins are important to the cell  for transportation functions mainly. They will both be involved in  transporting molecules or ions across the semi-permeable membrane  of the cell.
Every protein molecule sooner or later reaches the end of its  lifetime. This might be for example when oxidative damage has  degraded it to the point where it cannot fulfill its function.    The only option left to the cell in this case is to somehow get rid  of the damaged protein. A...
I'm not sure what you mean by 'lost its 3D' but I think you might  mean when a protein is broken down or heated it becomes denatured.
Precipitation of protein is the downstream processing of biological  products in order to concentrate proteins and rid them of various  contaminants.
Proteins are polymers!! Long chains of amino acids....
In general terms, proteins are molecules consisting of one or more  polypeptide chains. Proteins can be formed by about 40 to over 4000  amino acid residues, and to have a molecular mass from around 4  daltons to over 440 kD. Moreover, depending upon its function,  proteins can be formed by a...
SSome scientists call protein a small peptides, that is, molecules  with less than 25 amino acids. However, a typical small and very  important protein is the insulin. This protein is crucial for the  metabolism to regulate glucose in blood stream. Insulin is formed  by two amino acid chains...
The enzyme pepsin digests proteins.
Proteins are made up of sequences of amino acids. Amino acids are  molecules made up of a amino group (NH3), a  hydrogen (H), a carboxyl group ( O-C=O) and a variable group  which varies among amino acids and defines the function of  the amino acid.

They can be used in genetic modification as a vector to insert gene  into the genome of a target cell.    This has happened naturally in a few occasions, hence why much of  human DNA is derived from viruses (retroviral DNA).
Some proteins are polar (hydrophilic) and some proteins are  non-polar (hydrophobic), it depends on their function. Also, some  proteins can have both polar and non polar regions in their  structure
By the order of the amino acids that form them. Proteins aredistinguished from each other by the complexity of theirpolypeptide chains.
because it take o atom from protein 2 compose NH3
No. Endocytosis is a cellular event where fluids and particles are  embedded into the cell by pinching off the plasma membrane. When  the endocytosis is carried out by taking large molecules or  structures then the process is called phagocytosis. When the  process is focused to take small...
Your question is ambiguous - the previous answer applies if your  question was "Which structures do proteins produce?"    However, if your question was actually "Which cellular structure  produces proteins?", then you are looking for the ribosome. This is  a huge molecular complex which is...
Proteins are biopolymers with a wide range of molecular weights,  structural complexity, and functional properties. Natural proteins  are a high molecular weight polypeptide of L-amino acids that is  sinthesized by living cells.
Constitutively, proteins have no phosphorus as part of the  molecule. However proteins can be phosphorylated by kinase enzymes  that specifically add a phosphorus to certain amino acid residues,  most of the times in Serine, Threonine or Tyrosine residues.

Proteins are obtained from nutrients of food. They starts to digestin stomach by proteases such as pepsin, trypsin in to peptides.These small peptides later digested further to form amino acidsafter complete digestion.
Yes. An antigen is a substance that stimulates an animal in order  to produce an antibody reaction to counteract the substance by a  specific binding antibody-antigen. Most of the times this antigen  is a molecule of protein.
Yes. There's is a category of protein called ' Phosphoproteins'which contains phosphorous. Eg. Casein.
Yes. Proteins are polymers of aminoacids linked by peptide bonds  and formind long chains called polypeptides.
Proteins are beneficail in a way that it builds the body and act as regulators and catalyst in the cell. Insulin is a proteins that can reduce glucose levels and the revere can be carried out by glucagon. Haemoglobin protein is another example for carrying oxygen to our cells.
NO they are not common. Water is a polar molecule with one oxygen and two hydrogen.Fats and proteins are macronutrients that are made up of monomers such as amino acids.
Nucleic Acids
Proteins are a class of biological compounds consisting of chains of amino acids. They are one of the four major classes of organic molecules in an organism. (proteins, carbonhydrates, lipids, and nucleic acids). Proteins make up structureal components of an organism, transport material through a...
Polymers amino acid and carboxylic acid .
Protein molecules are digested by protease enzymes into one of 20 individual amino acids. amino acids
Carrier proteins performs the diffusion of different molecules. They found as an integral protein in the cell membrane. When its specific binding partner molecule binds to it, the protein undergoes conformational change that allows the transport of the solute molecule inside the cell. Glucose...
protease (a type of enzyme) breaks the peptide bonds between the  amino acids which make up the protein.
Proteins are designed in a way to accomodate the body's many functions in a way that allows for them to benefit the body's many naural functions in a healthy system.
Proteins are produced in all cells by protein synthesis. It requires the mRNA molecule produced from DNA in nucleus. Once it is transported to cytoplasm, ribosomes and tRNA molecules and enzymes will carry out protein synthesis.
The monomer of a protein is an amino acid.
what is the first protein complex photosynthesis
Peripheral and integral proteins are in the plasma membranes. Cell receptors such as insulin receptor, chemokine receptors such as CXCR4, CD4, hormonal receptors are all peripheral proteins. They do normally trigger the signalling by binding its specific ligand at the cell surface.
Just about every function in your body
Yes there is a little amount of protein present in potatoes. It is about 2g per 100g of potato. They are rich in carbohydrates that gives energy.
An enzyme called protease
No, proteins are made up of amino acids. monosaccharaides are  simple sugars such as glucose, fructose and galactose
Yes genes are responsible for proteins, but they not directly "making" it. There are cellular machinery in the cell that will synthesis proteins. Genes are DNA that transcribe the message into mRNA. This in turn translated to proteins by the machinery such as ribosomes.
There are not enough nutrients to support cell growth and DNA is damage
RNA creates proteins by copying your DNAstructure.
Translation produces proteins.
They can not directly synthesize proteins themselves since they lack the machinery. Virus infect its host and integrate its genome into the host. The most system then recognize virus as its own and helps to synthesize viral proteins.
Not all of them are catalytic. There is a class of proteins called enzymes that are catalyzing biochemical reactions. Enzymes are take part in the reaction to speed by the reaction without consuming itself, meaning they can be recycled to the next reactions. Protease, lactase, APOBEC3G are some...
About 0.5g or protein can be found in 100 g honey. Honey is a rich source of carbohydrates and not proteins. Honey can be added to the protein rich food that pair up well.
There is no such things exist as designer proteins. In bioinformatics, they design the three dimensional structure of proteins based on the available protein structures. Proteins earn it structures by intramolecular interactions.
proteins are digested by enzymes, called proteasees.Trypsin, pepsin are stomach enzymes that digest proteins into peptides. They further degraded by peptidases to form amino acids.
Generally it is recommended that about 10–35% of your daily calories come from protein. For an adult it would be about 50g of proteins required daily. In other words, at least 700 calories has been provided from protein diet to a person who take 2000 calories per day.
on the basis of chemical structure and solubility: globular protein; albumin;globulin;proalamines and histones on the basis of functions: structural protein;enzymes and catalyst protein;transport protein,hormonal p.; contractile p.; storage p.; genetic p.; defence p.; and receptor protein.
Proteins are made in cytoplasm by ribosomes. It requires transcribed mRNA from the nucleus. When mRNA meet ribosomes, tRNA carries amino acids according to mRNA codes and enzymes help to make peptide bond in between amino acids to form poly peptides and ultimately proteins.
Temperature is a key factor determines the protein's stability and activity. Most of the proteins loose their structure by heating above 80 degree Celsius(except thermo stable proteins such as Taq polymerase). Also the biochemical activiy of an enzyme is optimum at a particular temperature (mostly...
Short-lived proteins enable the cells to control their activities precisely and efficiently.
Yes hydrogen is present in protein back bone and peptide side chains. In addition proteins are rich in Carbon hence known as organic molecule. Traces of sulfur also their in aminoacids such as serine and threionine
They say Proteins are the building blocks of cells. They are broken down into amino acids where cells can use them for their functioning.
There are protein metabolic pathways presenting in cells and our digestive system. They are digested to simple amino acids by gastric enzymes such as proteases. The amino acids then taken up by our cells for the synthesis of our own proteins.
Yes about 1.5 g of proteins found in 10 g of mushroom. It is having some peculiar proteins such as lectins that has anit-cancer properties. It is also believed that they contain anti viral and bacterial protein, research is under progress.
No the soluble proteins can not pass though the transporters on the membrane. Transport proteins are highly specific they only allow the transport of ions such as Na or K across the cell. But transport proteins such as Hemoglobin can carry oxygen or CO2 to all the tissues for respiration.
egg's protein has undergone denaturation and loss of solubility, caused by the high rise of the temperature of the egg during the cooking process
No they are not. Proteins are synthesized as per the information present in the DNA or genes. So Genes are something which determine the phenotype or a character of an organism by making RNA and proteins.
All proteins contain carbon, oxygen, hydrogen and nitrogen. Somealso contain sulphur in the amino acids Methionine and Cysteine.

APOBEC is a class of deaminases that catalyse the deamination of viral DNA (cytidines) during their infection (SIV, HIV). Hemoglobin carries...
Proteins are synthesized in cytoplasm. mRNA is transcribed in the nucleus by DNA which will be exported to cytoplasm. The mRNA together with the machinery such as ribosomes, tRNAs and enzymes synthesize proteins.
1) Carrier protein ONLY transport the non-polar substance such as glucose,except water,because water particles could slide through phospholipid bilayer across plasma membrane from the area of high concentration to the area of lower concentration.2) Substance which pass through phospholipid bilayer...
yes hormonal proteins such as insulin or glucagon are chemical messengers. They bind to the cell receptor and activate the downstream pathway to trigger gene expression. In the case of Insulin it actually lowers the blood sugar when it boomed up.
DNA codes the information for proteins to be synthesized. It transcribe the message in to mRNA first. The mRNA exported out of the nucleus. In cytoplasm proteins are made by ribosomes, with the message coded in the mRNA.
