Biochemistry Murphy 301 CH 1-8 | Verified Questions And Answers | 100% Correct Quizzes The side chain of histidine has a typical pKa value in the range of 6.5-7.4. However, when analyzing the pKa values in a particular protein, scientists determined that one particular His residue has an unusually low pKa value of 4.8. Which of the following statements correctly explain this anomaly? 1) The microenvironment around a residue can impact its pKa value. 2) A positively charged amino acid must...

MCAT Organic ChemistryWhat are the four rules for writing resonance structures? - correct answer 1. Atoms must not be moved. Only electrons. 2. All resonance atoms must lie in the same plane. 3. Only valid Lewis structures are allowed. 4 . The number of unpaired electrons must remain constant. What are the two conditions for resonance? - correct answer 1. An atom must have a P orbital or a lone pair of electrons. 2. It must be single bonded to an atom that has a double or triple b...
