MCAT Organic Chemistry 2

Subjects : mcat, science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Molecules with the same atoms - but different bonds






2. Molecule can act as a base and as an acid






3. D and L describe what?






4. Enzymes that hydrolyze fats






5. 1. it requires an enzyme to linearize and mutarotate 2. it is not a reducing sugar and give negative Benedict's test






6. What describes the affinity of functional groups for a proton?






7. Unique feature of glycine






8. Sugar with a carbonyl group at the 2 carbon position






9. Amino group placed on the right of a fischer projection is a?






10. Glycosidic linkage of sucrose






11. Enzyme that hydrolyzes maltose into 2 glucose molecules?






12. Rule for all amino acids that are nonbasic and nonacidic pertaining to pI value?






13. 2 covalent bonds formed in proteins






14. Adjacent polypeptide strands running in opposite directions in Beta pleated sheet structure






15. Acetic acid formula?






16. Interconversion btw two anomers






17. Fxn of cholesterol in the membrane?






18. Amino group placed on the left of a fischer projection is a?






19. Physiological pH






20. Storage form of fatty acid that is composed of 3 esterified fatty acid to a glycerol molecule






21. 3 physiological roles of lipids






22. Unique feature of proline






23. Glyceraldehyde






24. Fatty acid structure






25. 2 reasons why fats have more efficient energy stores than carbs






26. Generated btw either thiols on different proteins or thiols on the same protein






27. Sugar with an aldehyde at the first carbon position






28. Covalent bond formed btw carboxyl group of one atom and the amino group of another amino acid in an addition - elimination mechanism - enzymes are required to carry out rxn






29. What kind of lipids compromise the lipid bilayer?






30. Fatty acid w/ one or more double bonds in cis form predominately






31. Glycosidic linkage of lactose






32. 1.has partial double bond character due to resonance 2. it cannot rotate 3. amide H is someWhat acidic and can H bond






33. Structure where H bonds occur btw residues distant from each other - or on a separate chain. backbone is extended rather than coiled






34. (R) and (S) describe what?






35. Right handed helix w/ carboxyl of one amino acid bound to the amine of another amino acid three residues away - proline never resides in this structure b/c it would place a kink in the helix






36. Nonpolar - hydrophobic amino acids






37. Carbon that in linear form has a carbonyl - or in cyclic form has a hemiacetal or an acetal






38. Separation is due to charge - with negative charge moving toward positive electrode and positive charge moving toward negative electrode

41. Epimers of sugars that vary in the configuration of their anomeric carbons






42. Naturally occurring carbohydrates are formed from what?






43. Acidic amino acids






44. Glycosidic linkage of maltose






45. 4 causes of denaturation of proteins






46. Histidine

48. Hydrophilic amino acids






49. Initial folding of proteins into shapes stabilized by H bonds btw amino and carboxyl groups of backbone
