Document Summary

Food taken in, taken apart, and taken up is the process of animal nutrition. Omnivores regularly consume animals as well as plants or algae. An animal"s diet must supply chemical energy, organic molecules, and essential. Four classes of essential nutrients: essential amino acids, essential fatty acids, vitamins, and minerals. Animals require 20 amino acids and can synthesize about half from molecules in their diet. Remaining amino acids, the essential amino acids, must be obtained from food in pre- assembled form. Meat, eggs, and cheese provide all essential amino acids and thus complete proteins. Most plant proteins incomplete in amino acid composition. Some animals have adaptions that help them when their bodies demand extraordinary amounts of protein. Animals can synthesize most of the fatty acids they need. Essential fatty acids must be obtained from their diet. Include certain unsaturated fatty acids (fatty acids with one or more double bonds) Vitamins are organic molecules required in the diet in small amounts.
