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.

Winter Colza:
Fricola:
New generation "00" winter rapeseed.
Excellent productivity and very regular in various growing conditions. Very good starting hardiness. Not too sensitive to elongation during early plantings. Mid-late flowering and maturity precocity. Medium size. Good weight of a thousand seeds that gives better chances in the emergence. Sow in cold areas during the first half of October and in warm areas up to the first half of November. It is recommended to seek 40-45 plants/m2 at the end of winter. Sow with 6-8 kg/ha to avoid emergence problems.
Spring Colza:
Valle de oro: ALTERNATIVE NEW VARIETY TO THE RAPESEED "00".
High oil content.
HARDINESS AND EXCELLENT PERFORMANCE.
MEDITERRANEAN ALTERNATIVE TYPE
It has achieved excellent results in production, exceeding more than 10% the currently most planted varieties.

Con el paso de los años, nuestro organismo va perdiendo la capacidad de retener determinadas vitaminas, que afectan directamente a la salud de nuestra piel y de nuestro organismo. Se trata de las Vitaminas C, A (Retinol), E. La vitamina C permite la formación de colágeno pro parte de nuestro organismo.
La vitamina A (retinol) previene el envejecimiento celular y protege las células, y la vitamina E, es un potente antioxidante.
Necesitamos mantener los niveles adecuados de estas vitaminas, ya que son las encargadas de protegernos frente a las agresiones medio ambientales, polución, virus encapsulados y bacterias, por lo que debemos ayudar al organismo ingiriéndolas vía oral.
Modo de empleo:la administración adecuada es de una cápsula al día. Ingerirpor la mañana junto con el desayuno

Acetyl-CoA is an essential cofactor and carrier of acyl groups in enzymatic reactions. It is formed either through the oxidative decarboxylation of pyruvate, through ß-oxidation of fatty acids or through the oxidative degradation of certain amino acids. It is an intermediate in fatty acid and amino acid metabolism. It is the starter for the citric acid cycle. It is a precursor to the neurotransmitter acetylcholine.
