Fatty acids isolated from the distal limb of a reindeer duri

Fatty acids isolated from the distal limb of a reindeer during winter would consist of _____ Select one: saturated fatty acids only. unsaturated fatty acids only. fatty acids that aggregate to form triglycerides. more unsaturated than saturated fatty acids.

Solution

In winter seasons, the fatty acid content of the body must comprise of more unsaturated fats so that fluidity of the membranes could be maintained. This comprises both, fatty acids and triglycerides because both of them are essential parts of the membrane. The distal ends of the limbs are particularly sensitive to these fatty acid compositions and hence, contain large amount adipose tissue comprising of fatty acids. Such types of fats are easy to accomodate and hence found in large concentrations in the distal ends of dwellers of cold regions.

Thus, choice c is correct.
