Henderson-Hasselbach Equation Ans- pH = pKa + log ([A-] / [HA]) Salting Out (Purification) Ans- Changes soluble protein to solid precipitate. Protein precipitates when the charges on the protein match the charges in the solution. Size-Exclusion Chromatography Ans- Separates sample based on size with smaller molecules eluting later. Ion-Exchange Chromatography Ans- Separates sample based on charge. CM attracts +, DEAE attracts -. May have repulsion effect on like charges. Salt or acid ...

Metabolism (catabolism and anabolism) - Metabolism: sum of total chemical reactions in an organism, also the method by which cells extract and use energy from their environment. Catabolism: The process by which stored nutrients and ingested foods are converted to a usable form of energy. It produces simple products CO2, H2O, NH3, and building blocks such as sugars and fats that are used in anabolism. Anabolism: the process by which simple products and building blocks of catabolism are us...

ACS BIOCHEMISTRY EXAM WITH LATEST QUESTIONS AND ANSWERS___ well updated ß-turns (Correct Answer) - Tight u-turns with specific phi-psi angles. Must have gly at position 3. Proline may also be at ß-turn because it can have a cis-omega angle. Loops (Correct Answer) - Not highly structured. Not necessary highly flexible, but can occasionally move. Very variable in sequence. Circular Dichroism (Correct Answer) - Uses UV light to measure 2° structure. Can be used to measure destabili...

ACS Biochemistry EXAM QUESTIONS AND CORRECT DETAILED ANSWERS | EVERYTHING YOU NEED TO PASS Membrane lipids: phospholipids - ANSWER-Two classes: glycerophospholipids (aka phosphoglycerides) and sphingolipids. Both contain two non-polar tails, a platform they are linked to, and a phosphate-containing polar head group. Phosphoglycerides - ANSWER-class of phospholipids that have two fatty acid chains bound to the alcohol groups in glycerol, with the third alcohol group being bound to amino alcoho...

Henderson-Hasselbach Equation - pH = pKa + log ([A-] / [HA]) FMOC Chemical Synthesis - Used in synthesis of a growing amino acid chain to a polystyrene bead. FMOC is used as a protecting group on the N-terminus. Salting Out (Purification) - Changes soluble protein to solid precipitate. Protein precipitates when the charges on the protein match the charges in the solution. Size-Exclusion Chromatography - Separates sample based on size with smaller molecules eluting later. Ion-Exchange...
