Document Summary
Amino acids: an amino group (acidic, a carboxyl group (acidic) (o=c-o, a hydrogen, something else {r} (can be quite large or small) something else, is; aka the x factor . Protein structure: primary 1 , secondary 2 , tertiary 3 , quaternary 4 , all proteins have 1 , 2 , 3 ; only some proteins have 4 . Primary structure: a description of the covalent bonds (strong bonds) and the sequence of amino acids in a protein, peptide bonds are holding all of these together. Secondary structure: repeated spatial pattern, two types, alpha helix (twisted shape; looks like a ribbon) (strong structure, beta pleated sheet (flat, pleated sheet; like a flattened accordion) (strong structure, largely stabilized/held by hydrogen bonds. Tertiary structure: weak; (result of weak bonds, looks like a big glob because its 1 and 2 folded together, 3d pattern of folding, largely stabilized by weak bonds (hydrogen bonds and hydrophobic interactions)
