These values have been confirmed with volumes taken from crystal structures [4]. Also reported are extinction coefficient calculated assuming additivity using per Mcm for tryptophans, and per Mcm for tyrosines [5] , and the amino acid composition.

Amino acids IMGT classes of the 20 common amino acids Charge, hydrogen donor and acceptor atoms, and polarity of the amino acid side chains Formula of the 20 common amino acids and structural details of the side chains.

The molecular mass, in Daltons, of a molecule is the mass of the atoms by reference to hydrogen. The mean molecular mass of an amino acid is The mean number of atoms per amino acid is A polypeptide chain of 1kDa corresponds approximately to 8.
