Although the common amino acids all have accepted standard names,they can also be named using the IUPAC organic chemical nomenclature system.Below is the structure for the simplest amino acid,glycine.What would be its IUPAC name?

Question

The IUPAC name for glycine is 2-aminoethanoic acid. This name reflects the presence of an amino group (-NH2) and a carboxylic acid group (-COOH) on a two-carbon chain (-CH2-) of the molecule. Choice A, 1-hydroxy-2-aminoethanone, has an incorrect functional group (ketone instead of carboxylic acid) and an incorrect number of carbons in the chain. Choice B, 1-carboxy-2-aminoethanol, has an incorrect number of carbons in the chain and an incorrect functional group (-OH instead of -NH2). Choice C, 2-carboxy-2-hydroxyethanamine, has an incorrect number of carbons in the chain and an additional functional group (-OH), which is not present in glycine.
