I erased magnesium in the list of prosthetic groups, as magnesium is loosely bound. But copper is a prosthetic group.

I thought that one of the sentences was correct, but awkwardly worded.

"Since prosthetic groups are often vitamins or made from vitamins, this is one of the reasons why vitamins are required in the human diet."

I changed it to this (which I view to be logically equivalent):

"The role of vitamins as prosthetic groups is a main reason for their importance in the human diet."

This was reversed, apparently because vitamins also have a function as coenzymes. However, both sentences give the role as prosthetic groups as a main reason for their importance. I don't understand why the change was undone. —Preceding unsigned comment added by 74.79.137.216 (talk) 22:26, 23 May 2008 (UTC)[reply]
