3-methylcholanthrene, 20-methylcholanthrene

3-methylcholanthrene, 20-methylcholanthrene
A highly carcinogenic hydrocarbon that can be formed chemically from deoxycholic or cholic acid s, or from cholesterol; it induces the synthesis of cytochrome P-450 mRNA; the choice between 3- or 20- for the methyl group depends upon whether hydrocarbon (inner) or steroid (outer) numbering is chosen; in the latter case, the formal relationship to the cholic acid s and cholesterol is clear.
