is isoleucine acidic
Isoleucine. Isoleucine is very similar in structure to the amino acid leucine. Like all amino acids, it has an acidic group called a carboxylic acid, and a basic group called an amine as part of its structure.Its identity is determined by its side chain, which is a group that varies from one amino acid to the next and determines each amino acid's chemical properties.ike all amino acids, it has an acidic group called a carboxylic acid, and a basic group called an amine as part of its structure.
