<prompt> High energy compound is -ADPATPGIucose-6-phosphateAMP  <response>: Ans. is b i.e., ATP o A compound that liberates 7 Kcalmol or more on hydrolysis is called high energy compound, or a compound that on hydrolysis undergoes a large 7 kcalmol decrease in free energy DG under standard condition is called high energy compound, Le., DG - 7 Kcalmol. For example, ATP liberates 7.3 Kcalmol on hydrolysis.High energy compounds are: -Phosphate compounds : Nucleotides ATPQ, GTP, UTP, UDP-glucose, Creatinine phosphateQ, arginine phosphate, 1,3-bisphosphoglycerate, Phosphoenol pyruvate, inorganic pyrophosphate, Carbamoyl phosphateQ, amino acyl adenylate amino acyl AMP.Sulfur compounds : - CoA derivatives acetyl CoAQ, Succinyl CoA, fatty acyl CoA, HMG CoA, S-adenosyl methionine SAM, adenosine phosphosulfate.o A compound which liberates 7 Kcalmol on hydrolysis is called low energy compound, i.e., a decrease in free energy is 7 Kcalmol, i.e., DG -7 Kcalmol. Low energy compounds are glucose-1 -phosphate, fhictose-6-phosphate, glucose-6-phosphate, glycerol-3-phosphate, AMP, ADPQ.
