Coenzyme A Biosynthesis (early stages)

When cursor points to a box further details will be displayed in a tooltip window. If you click on the box you will change to appropriate reaction scheme or enzyme specification.

These early steps do not occur in mammals, which need pantothenic acid in their diet.
