“…Plant sterols are the main component of plant cell membranes. Their biochemical structure is tightly related to that of cholesterol: an extra ethyl group (sitosterol and stigmasterol) or methyl (campesterol) group at C-24 of the sterol side chain is responsible for the difference as compared with the cholesterol chemical formula (Othman, Myrie, & Jones, 2013;Weingartner et al, 2009). The absence of a double bond in the sterol ring, that is, the saturation of carbon atoms in the sterol ring, generates the corresponding plant stanols.…”

“…Le cholestérol peut être estérifié et rentrer dans les chylomicrons secrétés dans la voie lymphatique, ou être pris en charge par le transporteur ABCA1 et sortir aussi sous forme de HDL (revue Othman et al, 2013). Dans l'entérocyte, les phytostérols ne peuvent suivre ces circuits et sont réexcrétés dans la lumière intestinale par l'hétérodimère ABCG5/ABCG8.…”

“…Un argument fort est donné par les patients atteints de sitostérolémie génétique (Revue dans Othman et al, 2013). Ces patients, très rares (fréquence estimée à1/1 000 000, ou moins) sont homozygotes pour des variants défectueux des gènes codant pour les transporteurs ABCG5 et/ou ABCG8.…”
