Selenocysteine (Sec or U or Se-Cys) is the 21st proteinogenic amino acid and is incorporated biosynthetically into the proteins during translation. The amino acid is an analog of cysteine (Cys) with selenium in place of sulfur. The amino acid was first discovered by American biochemist Thressa […]
Rancid is the unpleasant smell or taste usually from decomposition or chemical change of fats and oils. Rancidity is determined by measuring the Peroxide Value, Acid Value, p-Anisidine (p-AV) testing, and Refractive Index (RI) of […]
Succinate dehydrogenase (SDH) is an enzyme complex found in the inner mitochondrial membrane of eukaryotes. SDH is the only enzyme that participates both in the Krebs cycle and the electron transport chain. In step 6 of the Krebs cycle, SDH catalyzes the oxidation of succinate to fumarate. The SDH is composed […]
Transamination is the chemical process by which an amino group is removed from alpha-amino acid and transferred to alpha keto-acids to synthesize an amino acid version of the alpha keto-acid and the keto-acid version of the […]
