purified cytochrome p-450g , a male-specific rat hepatic isozyme , was observed to metabolize progesterone to two primary metabolites ( 6 beta-hydroxyprogesterone and 16 alpha-hydroxyprogesterone ) , two secondary metabolites ( 6 beta,16 alpha-dihydroxyprogesterone and 6-ketoprogesterone ) , and one tertiary metabolite ( 6-keto-16 alpha-hydroxyprogesterone ) .
