31. Each complex contains noncovalently bound FMN, coenzyme Q and several iron-sulfur centers. 32. The haem molecule is synthesised from glycine and succinyl coenzyme A ( succinyl CoA ). 33. Vitamin B is one necessary prosthetic group to the enzyme methylmalonyl-coenzyme A mutase. 34. In biochemistry, the coenzyme thiamine is responsible for biosynthesis of acyloin-like compounds. 35. This coenzyme also contains a thiazolium moiety, which on deprotonation becomes a nucleophilic carbene. 36. It is a precursor to the coenzyme divalent or trivalent ions through the small intestine. 37. Vitamin B 6 is a coenzyme in the metabolism of carbohydrates, fats and proteins. 38. Thus, the two products are 5, 10-methenyltetrahydromethanopterin and reduced coenzyme F420. 39. Accordingly, many p97 / CDC48 coenzymes and adaptors have domains that can recognize ubiquitin. 40. The coenzyme Ca 2 + signaling pathways.
