Document Summary
Peptide bonds (between the carboxyl group and the amine group) Has a -cooh group, an -nh2 group, an h, and an r group (side chain) all surrounding an. Consists of a sugar (deoxyribose or ribose), phosphate group, and a nitrogen- containing base (a, t, c, g, u) Runs in two directions 3" and 5". Link between two sugars occurs between carbons connected by an oxygen. Fatty acids (the tail added on used loosely) There is a head group (glycerol, phosphate group) and fatty acid tails are attached. Different from monomers in a chain, because each tail is added to the head group. Act as structural components of the cell. Carry genetic material (instructions for how the organism works) Fats act as long- term storage of energy. Products of these reactions are not actually water, but h+ and oh- Polarity: directionality of the monomers two chemically distinct ends. This is why they can link together to form polymers.
