Esteróis
Os esteróis são um subgrupo de esteroides com um grupo hidroxila na posição 3 do anel A. Eles são componentes-chave das membranas celulares, onde modulam a fluidez e permeabilidade, e servem como precursores de moléculas biologicamente ativas como hormônios e vitaminas. Os esteróis também são importantes no estudo do metabolismo do colesterol e doenças relacionadas. Na CymitQuimica, oferecemos uma ampla seleção de esteróis de alta qualidade para apoiar sua pesquisa em bioquímica, endocrinologia e metabolismo de lipídios.
