Question
Chapter 27, Problem 47P
Interpretation Introduction
Interpretation:
The disease from which the boy is suffering should be determined.
Concept introduction:
Fatty acid is an aliphatic carboxylic acid chain. It can be either saturated or unsaturated. Natural fatty acids have even number of carbon atoms (28-40), and the chain is unbranched in nature. They are very important in the diet, as they act as fuel for the biochemical reactions inside the body.
