Question

Hydrolysis of phosphatidic acid by phosphatidic acid phosphatase yields ___________

(a) 1, 2-diacylglycerol

(b) 1, 3-diacylglycerol

(c) 1, 4-diacylglycerol

(d) 1, 5-diacylglycerol

I have been asked this question in semester exam.

This interesting question is from Biosynthesis of Triacylglycerols in portion Lipid Biosynthesis, Biosynthesis of Amino Acids, Nucleotides and Related Molecules of Biochemistry

Answer 1

The correct choice is (a) 1, 2-diacylglycerol

The explanation is: In the pathway to triacylglycerols, phosphatidic acid is hydrolyzed by phosphatidic acid phosphatase to form a 1, 2-diacylglycerol.
