Quantitation of pi - Study guides, Class notes & Summaries

BCH2333 - Building Blocks Part 2 (Thermodynamics, Nucleic Acids, Amino Acids & Peptides, Carbohydrates, and Lipids) Quantitation of pI - Answer- pI can be quantified by Henderson-Hasselbalch equation: (pKa^-1 + pKa^+1)/2 the average of the pKas relates to the ionization of the zwitterion pI of Proteins (polyampholytes) - Answer- Proteins contain up to hundreds of pH-responsive groups; when the net charge of protein is 0, anions balance cations and the pI is reached @pH<pI, net charg...

What is a photomultiplier? - A vacuum tube consisting of a photoemissive cathode, a series of intermediate electrodes called dynodes, and a collection anode. What does a single-beam spectrophotometer do? - A single-beam spectrophotometer employs one beam of radiation that irradiates one cell. What happens in a deuterium lamp? - The lamp energy from the power source produces an excited deuterium molecule that dissociates into two atoms in the ground state and a photon and the energies of th...

Statistical Model A statistical model is a class of mathematical model, which embodies a set of assumptions concerning the generation of some sample data, and similar data from a larger population. A statistical model represents, often in considerably idealized form, the data-generating process. The assumptions embodied by a statistical model describe a set of probability distributions, some of which are assumed to adequately approximate the distribution from which a particular data set is s...
