Secosteroid
A secosteroid is a molecule similar to a steroid but with a "broken" ring. The word is from verb Template:Lang-lat = to cut,[1] - Template:Lang-lat "solid, three-dimensional",[2] - oid, from Template:Lang-grc "form".[3]
Secosteroids are very similar in structure to steroids except that two of the B-ring carbon atoms (C9 and 10) of the typical four steroid rings are not joined, whereas in steroids they are.
In humans, a well known secosteroid is vitamin D.
