Question

Quizplus · Accepted Answer

Amino acids are the building blocks of protein, and their primary function is to build proteins needed by the body. Although they can be used as a secondary source of energy, this is not their primary function. They do not provide vitamins or produce hormones like thyroxin and insulin. They also do not supply most of the kcalories in the average U.S. diet, as carbohydrates and fats are the main sources of energy. They do not insulate the body against temperature extremes.
