Improved organic compounds for increasing the uptake of selected substances by organisms, such as animals and fish

摘要

An acylamino acid for enhancing the bio-availability of substances in organisms by permabilisation of cell members, the acylamino acid having the general formula R1CONHCR2HCOOH, 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.
