Proteins

tRNA is a vital molecule that serves as an adapter in protein synthesis. tRNA does have amino acid acceptor arm where an amino acid is presented. But they do not have any protein on them.

Complement proteins are a group of proteins in the immune system that work together to enhance the body's ability to fight infections. They can help to attract immune cells to the site of infection, stimulate inflammation, and destroy pathogens by forming membrane attack complexes. Complement proteins play a critical role in the innate immune response.

Yes, proteins can be composted. However, they decompose more slowly compared to other organic materials due to their complex structure. It is recommended to balance protein-rich materials with carbon-rich materials in the compost pile to facilitate decomposition.

Electrophoresis is commonly used to separate plasma proteins by their electrical charge. In this method, a sample of plasma is subjected to an electric field, causing the proteins to migrate towards the oppositely charged electrode based on their charge. This separation allows for the visualization and quantification of different protein components in the plasma sample.

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 cell, and speed up needed chemical reactions.

Proteins are polymers of amino acids.

Another name for protein is polypeptide. They are made of many (poly = many) amino acids joined together by peptide bonds.

(Glycerol and fatty acids are the monomers of lipids)

Proteins are obtained from nutrients of food. They starts to digest in stomach by proteases such as pepsin, trypsin in to peptides. These small peptides later digested further to form amino acids after complete digestion.

I'm unable to show videos but I can provide information: Animal proteins, found in meat, poultry, fish, eggs, and dairy, are considered complete proteins as they contain all essential amino acids. Vegetable proteins, found in beans, lentils, nuts, seeds, and whole grains, can be combined to provide all essential amino acids as well. People can choose to consume a mix of both animal and vegetable proteins to meet their dietary needs.

Yes, chymotrypsin digests proteins. Chymotrypsin is included in the group of proteolytic enzymes called "serine proteases". This name is referred to their common catalytic mechanism characterized by a particular reactive Serine residue that is essential for their enzymatic activity.

Chymotrypsin is secreted from the pancreas and has a particular breakage activity of peptide bond from proteins. To do this, the protein to be digested has to have a Phenylalanine (Phe), Tryptophan (Trp), or a Tyrosine (Tyr) as bulky amino acid residues before the peptide bond to be cleaved. Moreover, when that particular amino acid residue, just before the peptide bond, is an Asparagine (Asn), Histidine (His), Methionine (Met) or Leucine (Leu), the breakage process is slower.

Finally, when the amino acid residue previous to the peptide bond is a Proline (Pro), the cleavage doesn't take place.

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.

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 itself made of RNA and proteins. Ribosomes float around in the cytoplasm, but many of them are also attached to the rough endoplasmatic reticulum.

Yes, sodium chloride can be used for protein precipitation. By adding sodium chloride to a protein solution, the high salt concentration can cause proteins to aggregate and precipitate out of solution, a process known as salting out. This method is commonly used in protein purification techniques.

The enzyme responsible for digesting proteins is called pepsin. It is produced in the stomach and helps break down proteins into smaller peptides for better absorption in the small intestine.

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 called A chain (21 residues) and B chain (30 residues), with small variants within mammal species.

Protein is important for wound healing because it is necessary for tissue repair, cell growth, and production of collagen, which is a major component of skin. Protein also helps to strengthen the immune system, which can reduce the risk of infection in the wound. Additionally, adequate protein intake can help speed up the healing process and improve overall recovery.

Yes, proteins are formed from amino acid monomers. The OH group on one end of the amino acid bonds with the hydrogen group on the other end to form a water molecule. Then the peptide bond forms (carbon-nitrogen-carbon)

Precipitation of protein refers to the process of proteins becoming insoluble and forming solid particles within a solution. This can be induced by changes in temperature, pH, or addition of specific chemicals, leading to the formation of a cloudy or solid material that can be separated from the liquid portion of the solution.

Lactose, a sugar found in dairy products, cannot be digested properly if the body does not produce enough lactase enzyme. This can lead to digestive issues such as bloating, gas, and diarrhea in individuals who are lactose intolerant.

Proteins (also known as polypeptides) are organic compounds made of amino acids arranged in a linear chain and folded into a globular form. The amino acids in a polymer are joined together by the peptide bonds between the carboxyl and amino groups of adjacent amino acid residues. The sequence of amino acids in a protein is defined by the sequence of a gene, which is encoded in the genetic code.
Protiens are made up of carbon, hydrogen, oxygen, nitrogen, and sometimes even sulfur.

These proteins are called self markers. They tell the immune cells that they belong in the body and they should be attacked.

Cell receptors (proteins) on the cell membrane mediate the inter cellular communications.

Not all enzymes are proteins. In general they are globular proteins. Enzymes that are proteins are long, linear chains of amino acids that fold to produce a three-dimensional product. Most enzymes can be denaturated, which means that they can be unfolded and inactivated, (by heating or chemical denaturants, which disrupts the three-dimensional structure of the protein.) Depending on the type of the enzyme, denaturation may reversible or irreversible.

Receptor proteins are specialized proteins that bind specific molecules, such as hormones or neurotransmitters, triggering a cellular response. Carrier proteins, on the other hand, are involved in transport processes, helping to move molecules across cellular membranes. While receptor proteins facilitate communication and signaling within the cell, carrier proteins play a more functional role in transporting molecules.

The cell membranes that can act as channels are called integral proteins. Peripheral proteins are the ones that are attached to just one side of the cell membrane.
