Y1 - 2014 N1 - T2 - Integrative Medical Biochemistry Examination and Board Review AB - High-Yield TermsAminotransferase: any of a family of enzymes that catalyze the transfer of an amino group between a α-amino acid and an α-keto acidAST and ALT: aspartate aminotransferase (AST; also called serum glutamate-oxaloacetate aminotransferase, [SGOT]) and alanine transaminase (ALT; also called serum glutamate-pyruvate aminotransferase [SGPT]), the two prevalent liver enzymes whose elevations in the blood have been used as clinical markers of tissue damageGlucose-alanine cycle: mechanism for skeletal muscle to eliminate nitrogen while replenishing its glucose supply. Glucose oxidation produces pyruvate which can undergo transamination to alanine; the alanine then enters the blood stream and is transported to the liver where it is converted back to pyruvate, which is then a source of carbon atoms for gluconeogenesisUrea: nitrogen compound composed of 2 amino groups (−NH2) joined by a carbonyl (−C=O) functional group; is the main nitrogen-containing substance in human urineKwashiorkor: an acute form of childhood protein-energy malnutrition with adequate caloric intake; characterized by edema, irritability, anorexia, ulcerating dermatoses, and an enlarged liver with fatty infiltrates SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/03/28 UR - accesspharmacy.mhmedical.com/content.aspx?aid=1122104274 ER -
