Title
(EN) A METHOD FOR THE PREPARATION OF A PHOSPHOLIPID WITH A CARBOXYLIC ACID RESIDUE IN THE 2-POSITION AND A PHOSPHOLIPID WITH AN $g(v)-3-FATTY ACID RESIDUE IN THE 2-POSITION
(FR) PROCEDE DE PREPARATION D'UN PHOSPHOLIPIDE A L'AIDE D'UN RESIDU D'ACIDE CARBOXYLIQUE EN POSITION 2, ET D'UN PHOSPHOLIPIDE A L'AIDE D'UN RESIDU D'ACIDE GRAS $g(v)-3 EN POSITION 2
Abstract
(EN)
The present invention relates to phospholipids with a desired carboxylic acid residue, such as an $g(v)-3-fatty acid residue, in the 2-position. These compounds are produced by esterifying a conventional lysophospholipid with the corresponding carboxylic acid in the presence of the catalyst phospholipase A2, the esterification taking place in a microemulsion with a water content not exceeding 0.1-2 % by weight.
(FR)
L'invention concerne des phospholipides comportant un résidu d'acide carboxylique voulu, tel qu'un résidu d'acide gras $g(v)-3 en position 2. On produit ces composés par estérification d'un lysophospholipide classique à l'aide de l'acide carboxylique correspondant en présence de la phospholipase A2 de catalyse, l'estérification ayant lieu dans une microémulsion ayant une teneur en eau ne dépassant pas 0,1 à 2 % en poids.
