11. For example, about 1000 enzymes are known to use the coenzyme NADH. 12. Pantothenic acid is used in the synthesis of coenzyme A ( CoA ). 13. It is the most common coenzyme in sulfotransferase reactions. 14. Pantetheine is an intermediate in the production of Coenzyme A by the body. 15. Pantetheine is an intermediate in the production of coenzyme A by the body. 16. This enzyme participates in coenzyme A ( CoA ) biosynthesis from pantothenic acid. 17. Adrenodoxin reductase is a mitochondrial flavoprotein as it carries a FAD type coenzyme . 18. Adenosylcobalamin is a coenzyme required for the activity of methylmalonyl-CoA mutase. 19. It is also a central component of coenzyme A. 20. This continuous regeneration means that small amounts of coenzymes can be used very intensively.
