*Stares blindly at her chem option booklet* This is killing me. Sigh.
*Flips the next page* Why do we have to study the darn structure of the protein in our body? *Mumbles* Amide linkage, hydrolysed by acid or alkaline hydrolysis or enzyme catalysed hydrolysis.
*Reads aloud* Primary structure, sequence of amino acids in polypeptide chain with covalent cross-linkages. Secondary structure, alpha helix, flexible and elastic. Beta-pleat sheet, flexible by inelastic. Tertiary structure, folding of alpha helix, interactions of R-groups. Van der Waals', ionic attractions, hydrogen bonding, disulphide linkages. Quarternary structure, oligometric proteins. Haemoglobin, 2 alpha-sub-units and 2 beta-sub-units. Little contact between pairs of units.
*Sighs heavily* This is getting me no where.
