Document Summary

Can also go in either direction in equilibrium. Can be ionized and be nh3 instead of nh2. Each base is attached to either a ribose or deoxyribose by the bond at n. Cells have 4 major families of organic molecules. Bunch of bonded sugar together through condensation reactions (see above) All carbons occupied by another carbon or hydrogen. Since carbon bonds can rotate (since they have a tetrahedral structure and can make 4 total bonds), the double bond is important because it locks the chain into position. Formed by the addition of three fatty acid chains to glycerol. Each organelle membrane is composed of two layers of lipid molecules. (amino group) h3n+ - alpha-carbon - coo- (carboxyl group acid) Carboxyl group gives h+ to amino group, becomes ionized. Look for the alpha-carbons and peptide bonds (c-n) Made of a base (guanine, cytosine, adenine, thymine, uracil) bonded to a sugar.
