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
