BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Tryptophan (symbol Trp or W) is an -amino acid that is used in the biosynthesis of proteins. Tryptophan contains an -amino group, an -carboxylic acid group, and a side chain indole, making it a polar molecule with a non-polar aromatic beta carbon substituent.

Detailed explanation-2: -Glutathione, also referred to as GSH, is an endogenous component of cellular metabolism, a tripeptide composed of glycine, cysteine, and glutamic acid.

Detailed explanation-3: -The N-terminal amino acid is Serine in the given peptide. It is the amino acid in which free carboxylic acid is present.

Detailed explanation-4: -Thus the name of the peptide begins with the name of the acyl group representing the N-terminal residue, and this is followed in order by the names of the acyl groups representing the internal residues. Only the C-terminal residue is represented by the name of the amino acid, and this ends the name of the peptide.
