- Conjugated Proteins
- Fatty Acid
- Enzyme Activity
- a temperature- denature and breaks H bonds; pH; substrate concentration; inhibitors (antibiotics) inhibit enzymatic functions
- b long hydrocarbon chain ending in a carboxyl group -COOH
- c Made up of repeating units of amino acids (about 20 types); Subunits linked by peptide bonds forming polymers; Function: structural support, antibodies, contractile fibers, toxins, transport.
- d m. wt. 10^3- 10^9; nucleic acids, proteins, lipids, polysaccharides. 4 most important to study.
- e amino acid with another component; glycoprotein; nucleoprotein; lipoprotein; phosphoprotein.
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.
- CO2, H2O, NH3, N2, etc.
- N-acetyl muramic acid; important sugar acids in bacterial cell walls
- glucose and glucose; glucose is a bad sugar
- glucose and fructose; bad for teeth
5 True/False questions
Protein Properties → Allosteric proteins- dual affinity (hemoglobin); denaturation and re-naturation of proteins; enzymatic activity (catalysts)- apo enzyme and holo enzyme; lowering of activation energy; E+S <-> [ES]-> Product + Enzyme
Lipids → glucose and galactose
Tertiary → 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.
Oligosaccharides → most important are disaccharides; covalent linkages of two monosaccharides with the release of H2O (glycosidic bond). i.e. sucrose, lactose, maltose, etc.
Hybridization → diagnostic technique; denature and add a known fluoresced DNA. Don't have to know base structure.
