Document Summary
Proteins contain: carbon, hydrogen, oxygen and nitrogen. Amino acids contain: carbon, hydrogen, an amino group, an acid group and a side. Proteins are more complex than carbohydrates or fats. Twenty amino acids: different characteristics, essential amino acids must be supplied through our diet, nonessential amino acids body can synthesize these, conditionally essential amino acids nonessential amino acids can sometimes become essential. Trauma/stress/injury body can sometimes not make the same levels of some amino acids, causing them to be essential because they must be gotten from diet. The side chains on proteins are always different and are often what give the proteins their unique functions. Condensation reactions can bond two amino acids to form more complex protein molecules: combined by a peptide bond. Amino acid sequencing: primary structure individual amino acids, chemical bonds, secondary structure when the protein starts to coil, electrical attractions, tertiary structure 3-d formation, determined by the original amino acid sequence, determines the function of the protein.
