Caroténoïdes
Les caroténoïdes sont une classe de tétraterpènes (C₄₀) qui sont des pigments naturels présents dans les plantes, les algues et les bactéries photosynthétiques. Ils jouent des rôles essentiels dans la photosynthèse et fournissent des couleurs vives allant du jaune au rouge dans divers fruits et légumes. Les caroténoïdes sont connus pour leurs propriétés antioxydantes et leurs potentiels bienfaits pour la santé, notamment en favorisant la santé oculaire et en réduisant le risque de certaines maladies. Chez CymitQuimica, vous pouvez trouver une variété de caroténoïdes pour des applications de recherche en nutrition, biologie végétale et sciences pharmaceutiques.
