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.

CAS :<p>trans-Crocetin - 70% is a highly purified carotenoid compound, which is derived from saffron (Crocus sativus) stigmas. Its molecular structure allows it to act as a potent antioxidant, disrupting oxidative stress pathways by scavenging free radicals and inhibiting lipid peroxidation. This mode of action is critical because it can potentially protect cellular components from damage and modulate various biochemical pathways.</p>Formule :C20H24O4Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :328.4 g/molCrocin I
CAS :<p>Crocin is a pharmaceutical product which is an antipyretic and analgesic medication, primarily composed of paracetamol (acetaminophen). It is synthesized through chemical processes originally derived from coal tar, although modern production predominantly utilizes petrochemical sources. The mode of action of Crocin involves the inhibition of cyclooxygenase (COX) enzymes, particularly COX-2, in the central nervous system. This action leads to a decrease in the synthesis of prostaglandins, which are responsible for pain and fever.</p>Formule :C44H64O24Degré de pureté :Min. 98.0 Area-%Couleur et forme :PowderMasse moléculaire :976.96 g/molFucoxanthine - 10%
CAS :<p>Fucoxanthine - 10% is a carotenoid compound, which is extracted from brown seaweeds such as Undaria pinnatifida and Laminaria japonica. This compound is known for its unique structure and biochemistry, which allows it to influence metabolic processes within the body. Fucoxanthine primarily functions by increasing the expression of uncoupling protein 1 (UCP1) in white adipose tissue, which in turn enhances lipid metabolism and thermogenesis. This action leads to a potential increase in energy expenditure and fat oxidation.</p>Formule :C42H58O6Degré de pureté :Min. 95%Couleur et forme :Yellow PowderMasse moléculaire :658.91 g/molAstaxanthin
CAS :<p>A xanthophyll pigment with characteristic reddish-orange colour. Often added to fish food since it is an essential nutrient for healthy fish growth and reproduction.
