Chem 219 Unit 3 Exam with Verified Solutions Stereochemistry - Answer -the study of the three-dimensional structure of molecules Stereoisomers - Answer -Compounds with the same structural formula and connectivity but with a different 3D arrangement of the atoms in space. Enantiomers - Answer -Stereoisomers that that are non-superimposable mirror images. Enantiomers have the same connectivity but different orientations (twist) of the four atoms or groups in 3D space. The two different forms...

Intro to Biochemistry (Murphy 301) CH 1 – 4 Questions and Answers 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 be in close proximi...
