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.

Alpha lipoic acid, also known as lipoic acid, is a naturally occurring compound that acts as a powerful antioxidant in the body. It is found in small amounts in certain foods and is also available as a dietary supplement. Alpha lipoic acid is unique in that it is both water-soluble and fat-soluble, which allows it to penetrate all parts of the body. It can easily cross cell membranes and enter cells, including those in the brain. This versatility makes it an effective antioxidant that neutralizes harmful free radicals in the aqueous and lipid fractions of cells.

La vitamine C (également appelée acide ascorbique ou acide L-ascorbique) est responsable de nombreux processus métaboliques dans le corps. Il intervient dans le métabolisme des glucides, des protéines et des graisses, ainsi que dans la synthèse de l'hémoglobine, des érythrocytes et de certaines hormones. La vitamine C existe sous forme oxydée ou réduite sous forme d'acide L-ascorbique. Il est très sensible à la destruction, principalement à cause de la lumière et de la chaleur.
