- Conjugated Proteins
- Uncompetitive Inhibition
- a amino acid with another component; glycoprotein; nucleoprotein; lipoprotein; phosphoprotein.
- b The inhibitor binds to ES complex so that further reaction does not take place - either forward or backward.
- 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 The localized twisting and folding of the polypeptide chain. A specific orientation in space. Two main types: the alpha helix and the beta sheet. Helix- parallel some of the strongest; alpha keratin-nails; spiderwebs. Pleated sheet- anti-parallel; Beta keratin- silk. 18% of all proteins are one of these two shapes; others are random coiling
- e all hydrocarbons have CH2 units (bad for health); animals
5 Multiple choice questions
- DNA and RNA; Basic Unit- nucleotide; Building Blocks- a cyclic pentose sugar; phosphate; nitrogenous base. DNA lacks a hydroxyl group making it more flexible.
- m. wt. 10^3- 10^9; nucleic acids, proteins, lipids, polysaccharides. 4 most important to study.
- Needed to disrupt electronic configurations; physiological temperature and pressure too low for most chemical reactions to take place. Enzymes serve to speed up reactions by lowering activation energy.
- proteins and RNA
- the actual sequence of the amino acids
5 True/False questions
Polysaccharides (glycans) → 10s-100s of polysaccharides; storage molecules, i.e., cellulose, chitin, glycogen; linear or branched; made of similar or different subunits.
Tertiary → the actual sequence of the amino acids
precursors from the environment → amino acid with another component; glycoprotein; nucleoprotein; lipoprotein; phosphoprotein.
Hybridization → diagnostic technique; denature and add a known fluoresced DNA. Don't have to know base structure.
Carbohydrates → general formula (CH2O)n; subunits linked by glycosidic bonds; poly hydroxy aldehydes or ketones and their derivatives; functions- structural support, nutrient and energy.
