Methionine: Biosynthesis, Chemical Structure and Toxicity

ISBN: 9781626182929 出版年：2013 页码：199 Alexander Snegursky Nova Science

This book is dedicated to a very specific and interesting molecule/substance, Methionine. Methionine belongs to the α-amino acid group and as one of the essential amino acids, Methionine is classified as nonpolar and one of two sulfur-containing proteinogenic amino acids. This substance is an intermediate in the biosynthesis of phospholipids, (i.e. carnitine, cysteine, lecithin, phosphatidylcholine, taurine, and others). It is also being utilized by plants in synthesizing ethylene. Methionine is one of only two amino acids encoded by a single codon (AUG) in the standard genetic code, therefore, it is incorporated into the N-terminal position of all proteins in eukaryotes and archaea during translation, although it is usually removed by post-translational modification. This book deals with the analysis of the most up-to-date data on Methionine properties related to its biosynthesis, electronic structure and toxicity issues. This book would be useful for students, post-graduates and scientists working in the field of studying amino acids, as one of the most prominent members of the family of molecules of biological relevance, tracing their basic properties and analyzing their practical applications in the field of pharmaceutics, medicine and molecular physics.
