Document Summary
Proteins = organic molecules composed of a folded chain of amino acids. Eaten to make the various body proteins essential to the body"s structure and function. Protein deficiencies (rare in na) challenge a person"s ability to grow + thrive. Amino acids = long chains that make proteins. Each amino acid has a nitrogen-containing amine group on one side and a carboxylic acid group on the other side. 21 amino acids found in our foods and bodies. Structurally identical except for their side chains. Some amino acids essential from diet, others can be synthesized by the body from other amino acids. Non-essential amino acids also have critical roles in body. Considered non-essential bc they can be made by modifying other amino acids. 6 are amino acids considered conditionally essential bc they become essential when body can"t make adequate amts (which can happen in certain disease states) Complete protein = when a food has all 9 essential amino acids.
