General description

Boc-L-cysteine (Boc-Cys-OH) is a high performance liquid chromatography (HPLC) grade chromatographic solvent.

Application

Boc-L-cysteine (Boc-Cys-OH) can may be used as a chromatographic solvent, in an experimental study done to study the biosynthesis of S-(3-hexan-1-ol)-glutathione (3MH-S-glut) and S-(3-hexan-l-ol)-L-cysteine (3MH-S-cys), which act as flavour precursors in wines, in Vitis vinifera grapes exposed to various environmental stress.

Other Notes

Chiral derivatizing agent used together with OPA for assaying the enantiomeric purity of amino acids

Alanine racemase is a pyridoxal-5'-phosphate (PLP)-dependent enzyme that reversibly catalyzes the conversion of l-alanine to d-alanine. d-alanine is an essential constituent in many prokaryotic cell structures. Inhibition of alanine racemase is lethal to prokaryotes, creating an attractive target for designing

d-Aspartate oxidase (DDO) is a flavin adenine dinucleotide (FAD)-containing flavoprotein that stereospecifically acts on acidic d-amino acids (i.e., free d-aspartate and d-glutamate). Mammalian DDO, which exhibits higher activity toward d-aspartate than d-glutamate, is presumed to regulate levels of d-aspartate in
