Verified step by step guidance

Identify the essential amino acids: Essential amino acids are those that cannot be synthesized by the body and must be obtained from the diet. These include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

Determine which amino acids from the options are essential: From the given options (I, G, P, A), identify which are essential. Isoleucine (I) is an essential amino acid, while glycine (G), proline (P), and alanine (A) are non-essential.

Understand the impact of deficiency: A deficiency in an essential amino acid can lead to various health issues because the body cannot produce it on its own. This makes deficiencies in essential amino acids more detrimental compared to non-essential ones.

Evaluate the options: Since isoleucine (I) is the only essential amino acid among the options, a deficiency in isoleucine would be most detrimental compared to deficiencies in glycine, proline, or alanine.

Conclude the reasoning: Based on the analysis, the deficiency in isoleucine (I) would be most detrimental because it is an essential amino acid, and the body relies on dietary intake to meet its needs.
