L-Cysteinyl-L-glutamine
L-Cysteinyl-L-glutamine is a dipeptide composed of cysteine (L-Cys) and glutamine (L-Gln). Cysteine is a sulfur-containing amino acid known for its role in forming disulfide bonds, which are critical for protein structure and stability. Glutamine, on the other hand, is a key amino acid involved in protein synthesis, nitrogen metabolism, and cellular energy. This dipeptide could be important in studies related to redox biology, protein folding, or cellular stress responses, particularly those involving glutathione synthesis, where cysteine is a precursor. Synonyms: CQ; Cys-Gln; H-Cys-Gln-OH; H-CQ-OH; L-Glutamine, L-cysteinyl-; Cysteinyl-glutamine. Grade: ≥95%. CAS No. 629653-15-2. Molecular formula: C8H15N3O4S. Mole weight: 249.29.
