This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Biochemistry
Metabolites in HMP shunt are all except 
Select and explain. 
A. Glycerol–3 phosphate, B. Sedoheptulose–7 phosphate, C. Glyceraldehyde–3 phosphate, D. Xylulose–5 phosphate
A: Glycerol–3 phosphate
Answer: A: Glycerol–3 phosphate 
Explanation: Glycerol-3 phosphate 

Glyceraldehyde-3-phosphate is produced (not glycerol-3-phosphate).
Metabolites in HMP shunt
Oxidative phase:- Glucose-6-phosphate → 6-phosphogluconate → Ribulose-5-phosphate.
Non-oxidatative phase :- Xylulose-5-phosphate, Ribose-5-phosphate, sedoheptulose-7-phosphate, erythrose-4-phosphate, fructose-6-phosphate, glucose-6-phosphate, glyceraldehyde-3-phosphate.
