Chapter 15, Problem 31RE
Interpretation Introduction
Interpretation:
The correct or incorrect statement is to be deduced from the given statements, and reason for each of them is to be explained.
Concept introduction:
A coenzyme is a varied group of small nonprotein, organic, freely diffusing compounds that are loosely attached with an essential that allows enzymatic activity, acting as the carrier molecules that transfer electrons, chemical groups, etc. The well-recognized coenzymes comprise adenosine triphosphate (ATP), which transfer the phosphate groups; nicotinamide adenine dinucleotide (both NADH and NADPH), which transfers hydrogen and electrons; coenzyme A, which transfers the acetyl groups; and the S-adenosylmethionine coenzyme, which transfers the methyl groups.

Cholesterol synthesis begins with the formation of mevalonate from acetyl CoA. This
process activates mevalonate and converts it to isopentenyl pyrophosphate.
Identify the atoms in mevalonate and isopentenyl pyrophosphate that will be labeled
from acetyl CoA labeled with 14C in the carbonyl carbon. Place 14C atoms and C atoms
to denote which carbon atoms are labeled and which are not labeled.
