AbstractOleic acid (cis‐9‐octadecenoic acid) was converted in excellent yield to the estolide, which was then esterified with 2,2‐dimethypropan‐1‐ol (neopentyl alcohol), cis‐9‐octadence‐1‐ol (oleyl alcohol), and 2‐propanol to generate the corresponding estolide esters. Higher‐formula mass estolide esters were synthesized by reaction of the parent estolide with 1,3‐propanediol, 2,2‐dimethyl‐1,3‐propanediol, and 1,5‐pentanediol to give the corresponding diesters of oleic estolide, thus doubling the molecular size of the parent estolide. Pour points and viscosities were determined in order to evaluate these products for possible industrial application.

Disclosed herein is a lipid having a net charge at physiological pH, and being covalently attached to a lipid moiety. The lipid moiety comprises a hydrocarbon structure having two or more linked hydrocarbon chains, optionally having cis or trans C=C, at least one of said chains being covalently attached to the head group optionally via the linker region. The hydrocarbon chains are bonded to one another at a branch point at an internal carbon of the chain attached to the linker region, which branch point comprises a functional group having an electronegative atom. The hydrocarbon chains each have between 1 and 40 carbon atoms, wherein the hydrocarbon structure in total comprises between 10 and 150 carbon atoms. Advantageously, the hydrocarbon structure may assume a generally flared shape for enhanced delivery of cargo molecules. Further provided are delivery vehicles comprising the lipids.
