Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Heavy metals in municipal waste incineration fly ash are potentially harmful to the ecological environment and human health. To mitigate the hazards of fly ash, this study attempts to detoxify fly ash through organic acid washing pretreatment coupled with cement/sodium diethyldithiocarbamate (DDTC) solidification.

A new sulfur-containing amino acid
Archives of Biochemistry and Biophysics, 1961Abstract A new acidic amino acid (C8H15O4NS) containing cysteine residue was isolated from the urine of an atherosclerotic patient. It melted at 213 ° with decomposition. Crystalline form is rhombic plate from 50% alcohol. Ninhydrin color is blue on paper chromatogram. Rf values are 0.58-0.65 in butanol-acetic acid-water and 0.43-0.53 in phenol-water.

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 ...

Immunonutrition: role of sulfur amino acids, related amino acids, and polyamines
Nutrition, 1998Pro-inflammatory cytokines mediate widespread changes in protein metabolism. Amino acids released from peripheral tissues fulfill a number of functions. They act as substrate for acute phase protein and immunoglobulin synthesis and, together with polyamines, in the replication of immune cells.
