 In humans, it is also the precursor for hormones (i.e., estrogen, testosterone).It is synthesized via squalene and naturally assumes a specific stereochemical orientation (3β-ol, 5α (H), 14α (H), 17α (H), 20R).This stereochemical orientation is typically maintained throughout diagenetic processes, but cholestane can be found in the fossil record with many stereochemical configurations.
