Document Summary
*saturated fat is a solid at room temperature* unsaturated fat is a liquid at room temperature. B phospholipids: phospholipids mostly in membranes, 1 glycerol, 2 fas, & 1 polar group, like a triglyceride, 1 fa swapped for a polar group, soap-like properties, likes to get between polar and nonpolar materials. C steroids: complex ring forms, some hormones, cholesterol, natural substance, found in membranes, what are proteins, proteins are amino acid polymers, many roles in a cell, enzymes, hormones, structures, amino acids. Small molecules 20 kinds: a. 1 carboxyl group: c. 1 r group, 1 of 20 possibilities. Joined by peptide bonds to form polypeptide. 3 basic types of amino acids: hydrophilic, hydrophobic, forms disulfide bridges. Levels of protein structure: primary: the sequence of amino acids linked by peptide bond, secondary: coiling of the chain, tertiary: coiling of the coil, quaternary: two or more chains together.
