BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Glycine (symbol Gly or G; (listen)) is an amino acid that has a single hydrogen atom as its side chain. It is the simplest stable amino acid (carbamic acid is unstable), with the chemical formula NH2‐CH2‐COOH. Glycine is one of the proteinogenic amino acids.

Detailed explanation-2: -Glycine (Gly/G) is the amino acid with the shortest side chain, having an R-group consistent only of a single hydrogen. As a result, glycine is the only amino acid that is not chiral.

Detailed explanation-3: -Background: Glycine is the smallest nonessential amino acid and has previously unrecognized neurotherapeutic effects.

Detailed explanation-4: -Glycine is a nonpolar amino acid. It is the simplest of the 20 natural amino acids; its side chain is a hydrogen atom. Because there is a second hydrogen atom at the ± carbon, glycine is not optically active. Since glycine has such a small side chain, it can fit into many places where no other amino acid can.

Detailed explanation-5: -Glycine essentially lacks a side chain and therefore can adopt conformations which are sterically forbidden for other amino acids. This confers a high degree of local flexibility on the polypeptide.
