Question

22) Proteins must be complex set of mol bond formation eins must bend and fold as they are synthesized with a x set of molecules assisting in this process. Disulfide formation helps to guide and stabilize this protein folding. What type of reaction is disulfide bond formation? a) oxidation-reduction b) acid-base c) isomerization d) splitting ("lysis") e) high energy bond transfer SH HS s-s Cys, free cysteines disulfide bor 23) Which of the following has a hydrophobic side chain? a) serine b) aspartate c) lysine d) glutamine e) proline

Answer 1

22. In free cysteines , sulfur is in -2 oxidation state but in Disulfide bond sulfur is in -1 oxidation state. It means here oxidation of sulfur is taking place.

Correct option is : a) Oxidation - reduction

23. Correct option is : e) Proline
