WebJan 16, 2024 · A pH 7 amino acid has a net charge of 0, 1, or -1. Because amino acids are made up of carboxylic acid and amine groups, they are frequently neutral at neutral pH (pH 7), but acidic amino acids, such as … WebAcidic and Basic Amino Acids. There are three amino acids that have basic side chains at neutral pH. These are arginine (Arg), lysine (Lys), and histidine (His). Their side chains contain nitrogen and resemble ammonia, which is a base. Their pKa's are high enough that they tend to bind protons, gaining a positive charge in the process.
