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.

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






21. What kind of lipids compromise the lipid bilayer?






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