LécithineLa phosphatidylcholine est plus connue sous le nom lécithine.
Au sens le plus strict, la lécithine désigne uniquement les phosphatidylcholines c'est-à -dire un lipide formé à partir d'une choline, d'un phosphate, d'un glycérol et de deux acides gras (figure). Dans ce contexte, il serait plus juste de parler des lécithines, car il ne s'agit pas d'une seule molécule mais d'un groupe dont la composition en acide gras varie d'une molécule à l'autre. Ainsi, les lécithines vont adopter diverses couleurs selon leur composition : du jaune, pour la lécithine végétale, au brun, pour la lécithine de poisson.
Le terme de lécithine est aussi utilisé par extension pour désigner l'ensemble des phospholipides extraits du vivant (par exemple le soja), dans la mesure où ils sont majoritairement constitués de phosphatidylcholine.

| Résumé : |
When taking a closer look at nature, it quickly becomes apparent that lecithin is omnipresent : from plants and animals to human beings, there is no life without this essential agent. Lecithin is the collective term for mixtures of phospholipids and (in many cases) other lipids. Our endogenous cells are surrounded by a cell membrane that is largely composed of phospholipids, which means it occurs naturally in our bodies. It can also be obtained industrially from plants such as soy, sunflower and rapeseed, as well as egg yolk.
Before diving into the complex field of lecithin applications, it is important to know that not all lecithin is the same. It has numerous and varied qualities suitable for a broad range of applications, both as an active ingredient and functional substance. Its use is therefore favoured by the cosmetics, food, pharmaceuticals, dietary supplements and animal feed industries.
This article is about lecithin fractions, i.e. lecithin containing a high proportion of phosphatidylcholine and their applications in cosmetics. |
