Stérols
Les stérols sont un sous-groupe de stéroïdes avec un groupe hydroxyle en position 3 du cycle A. Ils sont des composants clés des membranes cellulaires, où ils modulent la fluidité et la perméabilité, et servent de précurseurs à des molécules biologiquement actives comme les hormones et les vitamines. Les stérols sont également importants dans l'étude du métabolisme du cholestérol et des maladies connexes. Chez CymitQuimica, nous offrons une large sélection de stérols de haute qualité pour soutenir vos recherches en biochimie, endocrinologie et métabolisme des lipides.
