An acylamino acid for enhancing the bio-availability of substances in organisms by permeabilisation of cell membranes, the acylamino acid having general formula (I) wherein R1 is hydrogen, a primary, secondary or tertiary alkyl or alkenyl group and R2 is hydrogen, a straight or branched chain alkyl group or a straight or branched chain substituted alkyl group, the substituents being selected from thio, thioether, hydroxy, carboxy, quarternary ammonium, amide, heterocyclic, benzyl, substituted benzyl, amino, substituted amino groups and difunctional alkyl groups linking to the nitrogen atom. A preferred acylamino acid for incorporating into an animal or fish feed is 2-palmitoylaminoproprionic acid.

L'invention concerne un acide acylaminé qui permet d'augmenter la biodisponibilité de substances dans des organismes, par perméabilisation des membranes cellulaires, ledit acide étant représenté par la formule générale (I). Dans ladite formule, R¿1? est hydrogène, un groupe alkyle ou alcényle primaire, secondaire ou tertiaire, et R¿2? est hydrogène, un groupe alkyle à chaîne linéaire ou ramifiée, ou un groupe alkyle substitué à chaîne linéaire ou ramifiée, et les substituants sont choisis dans les groupes thio, thioéther, hydroxy, carboxy, ammonium quaternaire, amide, hétérocyclique, benzyle, benzyle substitué, amino, amino substitué et les groupes alkyle difonctionnels assurant la liaison avec l'atome d'azote. De préférence, on choisit l'acide 2-palmitoylaminoproprionique comme acide acylaminé destiné à être incorporé dans des aliments pour animaux, y compris les aliments pour poissons.
