Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which molecule is an isomer of Glyceraldehyde-3-Phosphate (G3P)?
A
DHAP
B
PEP
C
Pyruvic Acid
D
1, 3 BPG
Explanation: 

Detailed explanation-1: -Triosephosphate isomerase (TIM) catalyzes the interconversion of d-glyceraldehyde-3-phosphate (G3P) and dihydroxyacetone phosphate (DHAP).

Detailed explanation-2: -Dihydroxyacetone phosphate (DHAP) is an isomer of G3P, DHAP converts in its isomer and forms Glyceraldehyde – 3 – phosphate.

Detailed explanation-3: -Dihydroxyacetone phosphate (DHAP) and glyceraldehyde-3-phosphate (GAP) are. constitutional isomers, which can interconvert as part of glycolysis.

Detailed explanation-4: -Summary – DHAP vs G3P Since their molecular formula is the same, they are isomers of each other. DHAP is a three-carbon monosaccharide involved in triglycerides synthesis while G3P is a three-carbon monosaccharide that is an intermediate of the glycolysis pathway. Thus, this is the difference between DHAP and G3P.
