Explanation:

(D) is the correct answer.

Lysine, arginine and histidine

Amino acids

Proteins are made up of substances called amino acids. Proteins and amino acids are the components of life. Amino acids are the byproducts of the digestion or breakdown of proteins. Amino acids are used by the human body to create proteins that assist the body. Dissect food.

Lysine:

The amino acid lysine can be found in a variety of foods as proteins. For instance, other animal proteins, beans, cheese, pork, milk, brewer's yeast, yoghurt, and wheat germ. It qualifies as a charged aliphatic amino acid since it has a -amino group, -carboxylic acid group, and a side-chain lysyl.

Arginine:

Arginine, an essential amino acid, has a positively charged guanidino group. Arginine is well designed to bind the phosphate anion, and is often found in the active centers of proteins that bind phosphorylated substrates.

Histidine:

A vital amino acid for nourishment, histidine is also a precursor to various hormones, including thyrotropin-releasing hormone, and important metabolites that have an impact on the immune system, neurotransmission, renal function, and gastric secretion.
