BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Glycine. Glycine (Gly, G) is the simplest of the 20 naturally-occurring amino acids. As noted above, since R is just a hydrogen, glycine is the only natural amino acid that is not chiral at the alpha carbon.

Detailed explanation-2: -From the structure of glycine, it can be concluded that it does not contain chiral centre.

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

Detailed explanation-4: -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-5: -Glycine does not contain any chiral carbon (asymmetric carbon) because it has two hydrogen atoms attached to alpha carbon.
