Question:

What is the name of the compound given in the structure?

Options:

Glycine

Alanine

Proline

Threonine

Correct Answer:

Alanine

Explanation:

The correct answer is option 2. Alanine

Alanine or \(\alpha \)-alanine, is an \(\alpha \)-amino acid that is used in the biosynthesis of proteins. It contains an amine group and a carboxylic acid group, both attached to the central carbon atom which also carries a methyl group side chain. Consequently it is classified as a nonpolar, aliphatic \(\alpha \)-amino acid. Under biological conditions, it exists in its Zwitter ionic form with its amine group protonated (as \(−NH_3^+\)) and its carboxyl group deprotonated (as \(−CO_2^−\)). It is non-essential to humans as it can be synthesized metabolically and does not need to be present in the diet. It is encoded by all codons starting with GC (GCU, GCC, GCA, and GCG).

The given structure is of alanine
