Authored by two internationally recognized experts with an excellent track record, this much-needed reference summarizes latest research in the rapidly developing field of stereoselective synthesis of enantiomerically enriched amino acids, particularly of non-proteinogenic origin.

Biocatalytic Synthesis of Chiral Alcohols and Amino Acids
Lecture 11 Biosynthesis of Amino Acids

The liver is the major site of amino acid metabolism in the body and the major site of urea synthesis. The liver is also the major site of amino acid degradation, and partially oxidizes most amino acids,
There he carried out research on the use of amino acids as chiral educts in synthesis as applied to anatoxin. Currently he is an Associate Professor in Organic Chemistry at the University of Santiago. His current research interests are in the area of chirospecific, stereocontrolled synthesis.

Synthesis of Amino Acids. There are several ways in which α-amino acids can be synthesised using reactions we have already encountered:
Description. This is the first of five books in the Amino Acids, Peptides and Proteins in Organic Synthesis series. Closing a gap in the literature, this is the only series to cover this important topic in organic and biochemistry.
