1. Amino Acids
1.1. Parts of an amino acid
1.2. bound together by peptide bonds to form a polypeptide chain
1.2.1. oxygen from one amino acid's carboxyl group attacks 2 hydrogens on the amino group, forms water, then water leaves. Then, the carbon from the group that lost the oxygen binds to the nitrogen from the other amino acid. BOOM. peptide bond don form.
1.3. are all polar
2. Levels of Organization
2.1. Primary
2.1.1. linear sequence of amino acids
2.2. Secondary
2.2.1. folding of primary structure into alpha helix or beta sheet
2.3. Tertiary
2.3.1. folding of the secondary structure
2.4. Quaternary
2.4.1. two or more poly-peptide chains (tertiary structure) associating to create a Quaternary structure
