- amino acid
- Nucleic Acids
- a general formula (CH2O)n; subunits linked by glycosidic bonds; poly hydroxy aldehydes or ketones and their derivatives; functions- structural support, nutrient and energy.
- b DNA and RNA; Basic Unit- nucleotide; Building Blocks- a cyclic pentose sugar; phosphate; nitrogenous base. DNA lacks a hydroxyl group making it more flexible.
- c Biological catalysts- specific for a chemical reaction; not used up in that reaction; Apoenzyme: protein.
Co-factor: non-protein component; Coenzyme- organic cofactor (NAD, FAD); Holoenzyme-Apoenzyme + cofactor.
- d proteins and RNA
- e +NH3-CHR-COO-; dipolar charges neutralize each other; side chain determines the charge. Carboxylic group and amino group form the peptide bond (H2O leaves). Peptide glycosidic bonds most important; 150 in our body only 20 make proteins. you have 3AA that make a tripeptide 3^3= 27 different combinations. more than 200 AA in a protein on average.
5 Multiple choice questions
- one or more double bonds (mostly between 9 and 10); Plant and animals in cold climates.
- pyruvate, citrate, malate, etc.
- 10s-100s of polysaccharides; storage molecules, i.e., cellulose, chitin, glycogen; linear or branched; made of similar or different subunits.
- alters the topology of DNA molecules.
- most important are disaccharides; covalent linkages of two monosaccharides with the release of H2O (glycosidic bond). i.e. sucrose, lactose, maltose, etc.
5 True/False questions
NAG → N-acetyl neuraminic acid; important sugar acids in bacterial cell walls.
Secondary → The overall 3D structure of the polypeptide chain. Held together by different bonds: peptide, ionic, hydrogen, covalent, sulfhydryl, etc. Prions are proteins that don't take their correct 3D shape and are harmful; mad cow disease.
Fatty Acid → long hydrocarbon chain ending in a carboxyl group -COOH
Maltose → glucose and galactose
NAM → N-acetyl neuraminic acid; important sugar acids in bacterial cell walls.
