Amino acidsare molecules containing an amine group, acarboxylic acidgroup, and a side-chain that is specific to each amino acid. The key elements of an amino acid are carbon, hydrogen, oxygen, and nitrogen. They are particularly important in biochemistry, where the term usually refers to alpha...
pI calculation. The pI is the pH at which an amino acid is electrically neutral. For amino acids with ionizable side chains, determining the pI involves considering the ionization of the amino and carboxyl groups, as well as the side chain (R-group). For example, the pI of the amino ac...
(R)-(-)-2-Amino-1-propanol, with the chemical formula C3H9NO, has the CAS number 35320-23-1. It appears as a colorless liquid with a faint odor. The basic structure of (R)-(-)-2-Amino-1-propanol consists of a carbon atom bonded to three hydrogen atoms, an amino group (-NH2)...
