Question

what are acidic and basic amino acids?

Answer 1

Acidic and Basic Amino Acids. There are three amino acids that have basicside chains at neutral pH. These are arginine (Arg), lysine (Lys), and histidine (His). ... Their side chains have carboxylic acid groups whose pKa's are low enough to lose protons, becoming negatively charged in the process.

Answer 2

Basic amino acids

Amino acids containing more no.of amino (NH2) group than COOH group.Ex.lysine

Acidic amino acids

Amino acids containing more no.of COOH group than NH2 group.Ex.aspartic acid
