BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Glycine is achiral. It lacks chiral C atom.

Detailed explanation-2: -Glycine is the most simple amino acid. Glycine is the simplest amino acid. It’s sidechain (sometimes called the R-group) is one hydrogen atom. Because it has a hydrogen atom as its sidechain, glycine is the only achiral amino acid.

Detailed explanation-3: -Glycine and -methylalanine are achiral amino acids, but they become chiral when one of the hydrogen atoms of the methylene group of glycine or one of the methyl groups of -methylalanine are deuterated.

Detailed explanation-4: -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-5: -In the case of the amino acid, this includes the carboxylic acid functional group, the amine functional group, the various R-groups, and the hydrogen. Only glycine, which contains hydrogen as its R-group does not have chirality.
