Application:	β-Sitosterol has been used: • to study its ability to improve the suitability of two pollens • as a standard in the determination of sterol purities • as a standard in quantitative genetic analysis • as a standard in the estimation of plant sterols
Biochem/physiol Actions:	A phytosterol with structure very similar to cholesterol that exhibits estrogenic activity. Inhibits proliferation of human leukemia cells, with G2/M arrest, endoreduplication, and polymerization of α-tubulin and microtubules.
Biochem/physiol Actions:	Increased β-sitosterol administration displaces cholesterol during absorption. This elevates fecal secretion. It is known to regulate intestinal immunity.
Packaging:	10, 25, 100 mg in glass bottle
