Eubacterium coprostanoligenes, a small gram-positive and cholesterol-reducing anaerobe, promotes the conversion of cholesterol to coprostanol
(Madden et al.
La presencia de este microorganismo se correlaciona con el coprostanol
, esterol fecal encontrado en heces humanas (Cheryl et al 1995).

TO TRACK TRANSPORT
Of the 50 locations sampled in the study, Anne's Beach exhibited one of the highest concentrations of coprostanol
and cholesterol (indicators of human sewage).
had even a lower relative intensity compared with cholesterol and, like lathosterol, has not been reported to be present in concentrations in serum that would alter the results obtained by the CDC Reference Method for cholesterol .
And that change can be important, because unlike cholesterol, coprostanol
is not absorbed by the human body.
The enzyme reacts with cholesterol and converts it to coprostanol
, a sterol that passes through the body when consumed.
is produced in the digestive tract of humans by the microbial hydrogenation of cholesterol (Rosenfield & Gallagher, 1964).
