Concept explainers
(a)
Interpretation:
The amino acid alternation in the upper panel of graph A must be determined.
Concept introduction:
The fatty acids are degraded in a sequential manner, that is two carbon units at the carboxyl end of the molecule are removed in each step. The process of beta-oxidation of fatty acids degrades the fatty acids. The process of fatty acid synthesis is a stepwise process, which occurs by the addition of two-carbon units. These carbon units are provided by the acetyl-CoA, derived from glucose oxidation.
(b)
Interpretation:
The affect of mutation in colipase enzyme should be determined.

(d)
Interpretation:
The effect of above substitution on the ability of colipase to bind the lipase to the lipid particle must be determined.

These carbon units are provided by the acetyl-CoA, derived from glucose oxidation.
(e)
Interpretation:
The effect of the L16A mutation on lipase activity should be determined by analyzing the graph B.

(f)
Interpretation:
The lipase-binding and activation properties of the colipase enzyme must be determined.
