Document Summary

Muscle cells need physical activity and many nutrients not only protein! Have a structural and functional role in cells. Emphasis on protein (mainly meat) can often be at the expense of other foods in the diet. Excess meat may result in high saturated fat intakes. Found in milk, eggs, legumes, and many whole grains. *can get protein from a variety of different foods, not only meat! Amino acids amino: means nitrogen containing amino acids: links in a protein chain. Side groups on amino acids vary from one a. a. to another. Simplest" a. a. : glycine (has 1 hydrogen atom as a side group) Amino acids share a common structure but differ in size, shape, electrical charge nonessential amino acids (11) Fragments of carbohydrate and fat to form the rest of the structure. Protein from food generally supplies these a. a. essential amino acids (9) Cannot be made by the body in sufficient quantities.
