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. WebA Acidic amino acids: Those whose side chains can carry a negative charge at certain pH values. Typically aspartic acid, glutamic acid. Active site: Usually applied to catalytic site of an enzyme or where chemical transformations take place. Alignment: Tabulation of genetically related protein sequences arranged (using introduction of sequence gaps if …
