Amino Acid Structure Chart and Reference Table. Amino acids are the backbone of peptides and proteins. All amino acids contain both amino and carboxylic acids and in certain cases side chains.
The properties of amino acids are determined by the functional substituents linked on the side chains which are most commonly referred to as. The molecular weight calculator recognizes both one-letter code for 20 natural amino acids and three-letter code. When using the one letter notation please type your peptide sequences in capital letters as single words for example.
When using the three-letter notation separate amino acids with hyphens For example. The molecular weight mw of an oligopeptide or a protein can be determined by summation of the mw of its corresponding amino acid sequence. Certain modifications to this sequences can result in changes to the mw.
This calculator provides the mw of an unmodified oligopeptide or protein. Properties of standard amino acids and amino acids in proteins mass surface volume pKa pI solubility density of amino acids hydrophobicity solvent accessibility Ramachandran plots. Residue Weight -H 2 O pKa.

In particular the residues in least amounts methionine and cystine2 which at the molecular weight of best fit of 34700 give values of 101 and 406 resmole respectively are in the newer analysis found to be present in amounts of approximately 3 and 2 resmole respectively. In organic chemistry amines are compounds and functional groups that contain a basic nitrogen atom with a lone pair.
Amines are formally derivatives of ammonia wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group. Important amines include amino acids biogenic amines trimethylamine and aniline. See CategoryAmines for a list of amines.
