Notes

(1)

 In groups C 12 P 33/02 to C 12 P 33/20, the following terms are used with the meaning indicated:
 

-

 "acting", "forming", "hydroxylating", "dehydroxylating" or "dehydrogenating" means the action of a micro-organism or enzyme rather than other chemical action. [3]

(2)

 Attention is drawn to the Note following the title of subclass C 07 J, which explains what is covered by the term "steroids". [3]
