Infomation

Arginine is one of the twenty amino acids. It is most commonly found in its stereotypical L-isomeric formation and is a polar, positively charged molecule.

Due to the molecule's charge, it can sometimes be found located in the functional part of a protein conforming a pore.

Arginine displays basic properties in most basic, acidic and neutral environments due to the nature of its side chain or R-group. Its side chain contains a complex guanidinium cap on an aliphatic 3 carbon chain. Multiple H-bonds are able to form due to the conjugation of double bonds and lone pairs on the nitrogen atoms.
