Question
Chapter 35, Problem 8RQ
Summary Introduction
To determine:
The reason why certain amino acids are essential for humans but not for plants. Explain.
Introduction:
A nutrient is defined as ‘essential’ when it is needed by the organism but cannot be synthesized by the body. Thus, the nutrients must be ingested in foods and then digested and absorbed within the body. Vitamin C is needed for the growth and repair of tissue in all parts of the human body. It forms an important protein used to make skin, ligaments and blood vessels.

Stearate contains a total of 18 carbon (C) atoms and, when it is oxidized, a TOTAL of nine acetyl CoA molecules are produced. As you know, every molecule of glucose contains a total of six C atoms, so three glucose molecules have the equivalent number of carbons as one stearte.
