Which of the following amino acids is included in the GAVLIMP classification?

The GAVLIMP classification refers to a grouping of amino acids based on their hydrophobicity and side chain characteristics. Specifically, it includes Glycine (G), Alanine (A), Valine (V), Leucine (L), Isoleucine (I), Methionine (M), and Proline (P).

Valine is a branched-chain amino acid and is known for its hydrophobic properties, which make it a part of the GAVLIMP classification. This classification is often used in contexts such as protein folding and interactions, where the hydrophobic and hydrophilic characteristics of amino acids play a crucial role in stabilizing protein structures.

The other options listed—Histidine, Arginine, and Threonine—do not belong to this classification. Histidine and Arginine are both more polar and often participate in enzymatic reactions or interactions with other biomolecules, whereas Threonine contains a hydroxyl group that contributes to its hydrophilic nature, making it distinct from the primarily hydrophobic GAVLIMP amino acids.
