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: -Since the molecular formulas of DHAP and G3P are the same, we know that they are isomers of each other. The balance between DHAP and G3P is extremely important in regulating overall cell metabolism.

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

Detailed explanation-4: -Dihydroxyacetone phosphate (DHAP) and glyceraldehyde-3-phosphate (GAP) are. constitutional isomers, which can interconvert as part of glycolysis.

Detailed explanation-5: -DHAP is a three-carbon sugar involved in triglycerides synthesis while G3P is a three-carbon sugar that is an intermediate of the glycolysis pathway. So, this is the key difference between DHAP and G3P.
