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...

if the p-value is greater than 0.1, we generally conclude the data are consistent with the null hypothesis - true what is the best way to characterize the random error present in a measurement? - take replicate measurements of your analytes and using the standard deviation and a t-table specify an error bar with a confidence limit statistical interference assesses whether an observed phenomenon in the data can reasonably be attributed to chance or not - true suppose we collecte...

what factors explain the outcomes of reactions? hybridization, delocalization, eN, atom density what is a leaving group? - group of atom(s) that can be stable on its own - eN atoms that are good LG also make strong acids what is the α carbon? C directly attached to leaving group what are β Cs? β Hs? βC: C(s) attached to α carbon βH: H(s) attached to βC what is a LB? is it a nucleophile or electrophile? lewis base, nucleophile what is nucleophilic ...
