WebMay 19, 2024 · The lysine formula is C 6 H 14 N 2 O 2. It is an alpha amino acid, meaning that it has a central carbon that is attached to a carboxylic acid and an amino group. Lysine is specific type of... The most common role for lysine is proteinogenesis. Lysine frequently plays an important role in protein structure. Since its side chain contains a positively charged group on one end and a long hydrophobic carbon tail close to the backbone, lysine is considered somewhat amphipathic. For this reason, lysine can be found buried as well as more commonly in solvent channels and on the exterior of proteins, where it can interact with the aqueous environment. Lysine can also contrib… raymond usher bio

WebMar 16, 2024 · The side chain of lysine is an amine group, so I assume that when fully protonated it has positive charge ( N H X 3 X + ). At p H = 2, everything will be protonated because their p K a > p H. This gives a net 0 (carboxy) + 1 (amino) + 1 (side chain) = +2 charge. Why do sites such as this say that at p H = 2, lysine's charge is only +1, not +2? raymond utz
