Zwitterion 3 - Study guides, Class notes & Summaries

pKa (chapter 3) correct answers measure of the tendency of a group to give up a proton (acidity); tendency decreases tenfold as pKa increases by one unit thioester bond (1) correct answers compounds with functional group C-S-CoA-C (eg, in acetyl-CoA) zwitterion (3) correct answers dipolar ion with both positive and negative groups but overall neutral charge; can act as either an acid or base Isoelectric point (pI) (chapter 3) correct answers the characteristic pH at which the net electr...

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...

1) Amphiphiles - Molecules that have a polar and nonpolar end. 2) pH equation - pH=-log (H+) 3) HH equation - pH=pka +log(base form of buffer/acid form of buffer) 4) Effective buffer range of a buffer - 1 pH unit above and below the pka of the buffer 5) Zwitterion - The form of an amino acid when at neutral pH. (NH3+ end and COO- end) 6) Which amino acids exist in nature - The L isomer forms, not D 7) Does the peptide bond rotate - No 8) Orientation of most pep...
