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 astrand of mRNA, this is then transported to the nucleus where thetRNA combines with the mRNA to make codons (3 bases=1 codon) thesecodons then go into a ribosome and an...
Coca Cola dissolve the calcium on the chicken bone.
3.4=(32/y) * 100 --------> y=941.176g so, the least molecularweight 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 cellfor transportation functions mainly. They will both be involved intransporting molecules or ions across the semi-permeable membraneof the cell.
Every protein molecule sooner or later reaches the end of itslifetime. This might be for example when oxidative damage hasdegraded it to the point where it cannot fulfill its function. The only option left to the cell in this case is to somehow get ridof the damaged protein. A typical mechanism for...
I'm not sure what you mean by 'lost its 3D' but I think you mightmean when a protein is broken down or heated it becomes denatured.
Precipitation of protein is the downstream processing of biologicalproducts in order to concentrate proteins and rid them of variouscontaminants.
Proteins are polymers!! Long chains of amino acids....
Lots of proteins are lost through your blood cells.
In general terms, proteins are molecules consisting of one or morepolypeptide chains. Proteins can be formed by about 40 to over 4000amino acid residues, and to have a molecular mass from around 4daltons to over 440 kD. Moreover, depending upon its function,proteins can be formed by a single or...

Your question is ambiguous - the previous answer applies if yourquestion was "Which structures do proteins produce?" However, if your question was actually "Which cellular structureproduces proteins?", then you are looking for the ribosome. This isa huge molecular complex which is itself made of...
Proteins are biopolymers with a wide range of molecular weights,structural complexity, and functional properties. Natural proteinsare a high molecular weight polypeptide of L-amino acids that issinthesized by living cells.
Constitutively, proteins have no phosphorus as part of themolecule. However proteins can be phosphorylated by kinase enzymesthat specifically add a phosphorus to certain amino acid residues,most of the times in Serine, Threonine or Tyrosine residues.
somewhere in the cell
Apple is rich in dietary fiber, vitamins, carbohydrates or sugars and water. Protein content is very low (about 0.3 g per 100g of apple). Still, apple is a great source of vitamins and minerals that make us healthy.
Transport proteins are like enzymes because: . they combine specifically with a particular substance, with which they have a complementary shape so that binding is specific; enzymes bind to their substrate, transport proteins combine with the transported molecule. . they can be saturated ;...

There are prepared egg substitutes that reducethis content. Eggs / Protein (g) Egg, whole raw, 1 large 6.25g Egg, whole, raw, 1 medium 5.5g Egg yolk,...
Protein molecules are stabilized its structure by various non covalent interactions. When proteins exposed to advers pH or temperature (high or low) that are not favorable to its stability, they precipitate out from the buffer. The precipitated proteins generally lose its biological activity.
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 theamino 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.
Like phospholipids, proteins are also amphipathic. It means that protein molecules posses hydrophobic and hydrophilic regions in the same molecule. hydrophobic amino acids face inwards to form hydrophobic core, while hydrophilic residue face outwards toward the polar environment of the buffer or...
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.
When protein expresses inside the cell it is intracellular.. if protein express and secretes into the medium is extracellular.
Just about every function in your body
Proteins are found in meat,egg,plants are all perfect for our body functions. They digest in to amino acids in our body and provide essential amino acids for our own proteins synthesis. This term may also mean the stable proteins after undergoing folding after synthesis.
No that is a misconception. not all proteins are going to build our body muscle. Muscular proteins such as actin, myosin are the major part of our body muscle that contract for our movement. In addition fibrinogen and fibrins are are involved in blood clotting process.
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 aresimple 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.
Yes they are found as integral membrane proteins in addition to lipidis, glycerol and proteins alone. Glycoproteins are proteins that are post translationally coneected to sugar chains. Mostly the secreted proteins are also glycoslated.
Ovary is an organ and not proteins. protein is a macromolecule which made up of amino acids. Ovaries are a reproductive organ of a female that produce eggs or ovum.
Four polypeptide chains (2 heavy chains and 2 light chains) are present in an antibody molecule in its monomeric form.
Incomplete proteins are generally found in plant derived diet. The limiting (missing) amino acid in cereals is lysine. Hence this make cereal proteins incomplete because essential amino acids such as lysine can not be synthesized in the body hence need to taken from the diet. It can be mided...
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...
