- b general formula (CH2O)n; subunits linked by glycosidic bonds; poly hydroxy aldehydes or ketones and their derivatives; functions- structural support, nutrient and energy.
- c N-acetyl neuraminic acid; important sugar acids in bacterial cell walls.
- d N-acetyl muramic acid; important sugar acids in bacterial cell walls

5 Multiple choice questions
- Mostly single stranded; uracil in place of thymidine; mRNA; rRNA, tRNA
- DNA and RNA; Basic Unit- nucleotide; Building Blocks- a cyclic pentose sugar; phosphate; nitrogenous base. DNA lacks a hydroxyl group making it more flexible.
- pyruvate, citrate, malate, etc.
- End-product allosterically inhibits the action of first enzyme in pathway. prevents cell from wasting resources.
- temperature- denature and breaks H bonds; pH; substrate concentration; inhibitors (antibiotics) inhibit enzymatic functions
5 True/False questions
Macromolecules → Usually polymers; usually dehydration synthesis also called condensation rxn.
Unsaturated → all hydrocarbons have CH2 units (bad for health); animals
Polysaccharides (glycans) → most important are disaccharides; covalent linkages of two monosaccharides with the release of H2O (glycosidic bond). i.e. sucrose, lactose, maltose, etc.
precursors from the environment → CO2, H2O, NH3, N2, etc.
Saturated → all hydrocarbons have CH2 units (bad for health); animals
