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. Unique feature of cysteine






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






3. (+) and (-) describe what?






4. PH at which positive and negative charges balance to form a zwitterion






5. Diastereomers that vary in the configuration of 1 chiral center






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






7. Macromolecule that performs a variety of bodily functions and is composed of up to 20 different amino acids






8. Glyceraldehyde






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






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






11. Glycosidic linkage of lactose






12. 1. it exists in solution in equilibrium with linear form 2. mutarotation occurs readily 3. it is a reducing sugar - and reacts positively w/ Benedict's reagent






13. The amino acid sequence of a protein that is determined by peptide bond






14. Interconversion btw two anomers






15. Polar amino acids






16. Sulfur containing amino acids






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






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






19. Characteristic of basic amino acids






20. Hydrolysis






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






22. 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






23. Acetic acid formula?






24. 4 causes of denaturation of proteins






25. Fxn of cholesterol in the membrane?






26. Adjacent polypeptide strands running in the same direction in Beta pleated sheet structure






27. Enzyme that hydrolyzes maltose into 2 glucose molecules?






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






29. Unique feature of glycine






30. Basic amino acids






31. D and L describe what?






32. Glycosidic linkage of maltose






33. Formula for urea






34. Name for 6 membered ring






35. Fatty acid structure






36. Molecules with the same atoms and same bonds - but different bond geometries; can either be enantiomers or diastereomers






37. Sugar with an aldehyde at the first carbon position






38. 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






39. Acidic amino acids






40. 2 covalent bonds formed in proteins






41. PH at which the amino acid has a net neutral charge






42. What kind of lipids compromise the lipid bilayer?






43. Characteristics of hydrophobic amino acids






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






45. Physiological pH






46. Energy storage molecule of carbohydrates for animals






47. Interaction btw polypeptide subunits arranged in polypeptide. can be covalent bonds or intermolecular forces - disulfide bond that does not form btw residues on the same protein affect (blank)






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






49. Glycosidic linkage of cellulose






50. What stabilizes lipid bilayer?
