Construction of Thioamide Peptide via Sulfur-Involved Amino Acids/Amino Aldehydes Coupling.
Organic Letters, 2021A sulfur-involved ligation for thioamide quasi-peptides was developed via amino acids and amino aldehydes coupling. The key to the transformation was the chelation of copper with imines for chiral activation and fixation.

Journal of NutriLife, 2020
Metabolism of excess methionine (Met) to homocysteine (Hcy) by transmethylation is facilitated by the expression of methionine adenosyltransferase (MAT) I/III and glycine N-methyltransferase (GNMT) in liver, and a lack of either enzyme results in ...

Dietary Methionine and Total Sulfur Amino Acid Restriction in Healthy Adults
The Journal of Nutrition, Health & Aging, 2023Objectives Dietary restriction of methionine (Met) and cysteine (Cys) delays the aging process and aging-related diseases, improves glucose and fat metabolism and reduces oxidative stress in numerous laboratory animal models.

The reactions of the sulfur-containing amino acids with phosphoric and sulfuric acids
Archives of Biochemistry and Biophysics, 1951Abstract Both cystine and cysteine react very differently toward 6.0 M phosphoric and sulfuric acids. With phosphoric acid, extensive decomposi tion occurs; with sulfuric acid, very little. Cystine, in phosphoric acid at 100 °C. produces hydrogen sulfide, free sulfur, cysteic acid, ammonia, alanine, serine, and pyruvic acid.

Sulfur Amino Acids and Skeletal Muscle
Nutrition and Skeletal Muscle, 2019Methionine and cysteine are the two sulfur amino acids amongst the 20 standard ones incorporated into proteins. In addition to the dietary supply, cysteine can be synthetized from methionine and serine mainly in the liver but not in skeletal muscle.

Hair sulfur amino acid analysis
1997This overview emphasizes present aspects of sulfur-containing amino acids in hair. A selection of analytical procedures to determine cystine, cysteine, S-sulfocysteine, cystine oxide, cysteic acid, lanthionine and lysinoalanine are presented. The methods relate to intact hair or partial and total hydrolysates and comprise chromatography, titration ...

Sulfur amino acid metabolism and requirements
Nutrition Reviews, 2012The sulfur amino acids (SAA) are methionine and cysteine. Methionine is indispensable.1–5 It donates its sulfur atom to cysteine during the process of trans-sulfuration, making cysteine a dispensable amino acid.6 The carbon skeleton of cysteine, however, is donated by serine.6 Methionine is metabolized via three major metabolic pathways ...

Sulfur-containing amino acids and risk of schizophrenia
Schizophrenia Research, 2023Schizophrenia is a chronic and complex severe psychiatric disorder. Male and female are different in their risks for schizophrenia for the biologic and sociocultural reasons. Homocysteine (Hcy), Cysteine (Cys), and methionine (Met) play important roles in metabolism, and the three amino acids may also be involved in pathogenesis of schizophrenia.This ...
