These chains also dictate the molecular weight of the amino acids; for example, the molecular weight of glycine is 75 Da, and tryptophan is 204 Da. The weight increases depending on the side chain complexity of the amino acid structure. The R group also determines each amino acid’s polarity...

The dependence of the formation of NH 4 + and/or NO 3 ions on chemical structure has been examined in TiO 2 photocatalyzed oxidations of various amino acids, amides, and nitrogen-heterocyclic compounds. The primary amino groups and the amide moiety are converted photocatalytically and predominantly...
