Îmbătrânirea Uleiurilor Esențiale

Îmbătrânirea Uleiurilor Esențiale

Peroxydation et réaction intra-moléculaire Les huiles d’olive deviennent rance au cours du temps. Le rancissement est une modification chimique des structures moléculaire des huiles végétales. Les mêmes mécanismes chimiques opèrent aussi sur les huiles essentielles. La présence d’oxygène naturellement dissous dans les huiles, initie ces réactions chimiques. Elles s’accélèrent en présence de lumière, d’air, de sauts de température ou de diverses impuretés. Le mécanisme réactionnel de ce « vieillissement » se divise en deux étapes: la peroxydation et les réactions intramoléculaires (ou phase de propagation). La littérature scientifique décrit plusieurs exemples de peroxydation. Voici celui du linalol abondemment présent dans les huiles essentielles. (Exemple: lavande, lavandin, thym à linalol, bois de rose, sauge sclarée, etc). Dans ce shéma, le linalol subit en premier une peroxydation. Elle produit un nouveau composé: le 7-dydroperoxy-3,7-dimethyl-octa-1,5-diene-3-ol.

Vous souhaitez : déterminer une séquence pour identifier des mutations (mutations ponctuelles (SNPs), insertions, délétions) évaluer les liens de parenté entre individus ou populations mettre en évidence la présence d'un organisme donné dans un échantillon biologique réaliser un clonage dans un vecteur d'expression pour la synthèse d'une protéine recombinante... Ces analyses requièrent généralement une amplification de matériel génétique par une réaction enzymatique appelée PCR (Polymerase Chain Reaction). Cette réaction est généralement réalisée à partir d'ADN. Pour certaines applications spécifiques, on utilise comme matériel de départ de l'ADNc obtenu par transcription inverse d'ARN. Principe de la méthode Les molécules d'ADN, dans leur état naturel, sont constituées de deux brins complémentaires. Le passage à une température supérieure à 94 °C entraîne la séparation des deux brins de l'ADN et la destruction des structures secondaires (étape de dénaturation). Les molécules...
