Stéroïdes
Les stéroïdes sont une classe de composés organiques caractérisés par une structure moléculaire composée de quatre anneaux fusionnés. Ils jouent un rôle essentiel dans divers processus biologiques, notamment en tant qu'hormones régulant le métabolisme, la fonction immunitaire et la reproduction. Les stéroïdes sont largement utilisés en médecine pour leurs propriétés anti-inflammatoires, immunosuppressives et anabolisantes. Dans la recherche, ils sont étudiés pour leur potentiel thérapeutique dans le traitement de conditions telles que l'arthrite, l'asthme et les déséquilibres hormonaux. Chez CymitQuimica, vous trouverez une large sélection de stéroïdes, essentiels pour la recherche en pharmacologie, biochimie et le développement de thérapies à base de stéroïdes.
