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.

When the pH = pKa the solution is a buffer, and therefore half of the amino groups are protonated and half are deprotonated. The acid group will be deprotonated - not protonated, making it's charge -1. The pH is much greater than the pKa. The amino group will be half protonated (+1) and half deprotonated (0) for a net of "+0.5 ...

WebUnder physiological conditions (pH 7.4) in proteins the side chain usually occurs as the negatively charged aspartate form, −COO −. It is a non-essential amino acid in humans, meaning the body can synthesize it as needed. It is encoded by the codons GAU and GAC. D-Aspartate is one of two D-amino acids commonly found in mammals.
