Document Summary

Proteins: contain nitrogen (amino acids); supply 4 kcal/g of energy; regulate and maintain body structure (collagen, muscle, tissue), immune system hormones and enzymes, and satiety. Kno(cid:446) the basic structure of the amino acid: Amino acids: building blocks of proteins; amino= (cid:440)containing nitrogen(cid:441) Contains a central carbon with an amino group (nh2), an acid group (cooh), a hydrogen (h), and a side group. Essential (9): amino acids that the body requires but cannot make; must be provided in the diet. Nonessential (11): amino acids that the body can synthesize for itself; also known as dispensable amino acids. Glycine (the simplest amino acid, has a hydrogen atom as it"s side group) Conditionally essential amino acid: an amino acid that is normally nonessential, but must be supplied by the diet in special circumstances when the need for it exceeds the body"s ability to make it. Ex: the body normally uses the amino acid phenylalanine to make tyrosine (a nonessential amino acid).
