Which of the following amino acids would be easiest to distinguish from the other three in a titration? A. F - Phenylalanine.
B. K - Lysine.
C. V - Valine.
D. G - Glycine.

B. K - Lysine.

Explanation:

Required

The easiest amino acid to distinguish

The 4 amino acids in the question can be grouped into 2. The groups are:

(1) Group I - Nonpolar amino acids and (2) Group IV - Basic amino acids

Three of the amino acids belong to group I while the last belongs to group IV.

The acids according to their categories are:

(1) Group I - Nonpolar amino acids:- Phenylalanine, Valine and Glycine

(2) Group IV - Basic amino acids:- Lysine

Because Lysine belongs to a different group different from the other three, it will be easily distinguished because it will exhibit a different property from the other three acids.

ok whats the question if not i cannot you i need question and need a thing to answer
