Amino Acids Invloved in Protein Synthesis

Amino Acids Invloved in Protein Synthesis -

About ISO amino acids are found in nature, of which only 20 are specified by the genetic code.

Only these 20 amino acids take part in protein synthesis. Among the other amino acids found in proteins are cystine and hydroxyproline.

Cystine is a double amino acid consisting of two cysteine units. It is formed by oxidation which produces a disulphide linkage between two cysteine molecules.

This disulphide linkage plays an important part in maintaining the tertiary structure of proteins.

It is cysteine which is incorporated in the polypeptide chain during protein synthesis. Cystine is then formed as a result of interaction between two cysteine molecules.

Hydroxyproline, which is particularly found in collagen, is formed by the addition of hydroxyl (OH) group to proline after the latter has been incorporated into the polypeptide chain

The genes of a cell contain coded information for the maintenance and reproduction of the cell.

They direct the arrangement of the 20 types of amino acids into the polypeptide chains of the protein molecules.

A polypeptide chain typically contains about 100.300 amino acids and is formed by specific arrangement of the 20 types of amino acids.
