Abstract
Acylcarnitine chlorides [graphic omitted], with acyl chains containing ten or more carbon atoms form micelles in ethylene glycol. The critical micellar concentration was determined by means of difference spectroscopy using phenol as a probe and varied from 0.41 (C10) to 0.09 mol dm–3(C16) at 25 °C. The free energy of micellization, ΔG° m, at 25 °C ranged from –2.18 to –5.94 kJ mol–1. The solvophoic effect was determined to be –0.71 kJ mol–1 per—CH2—group compared with –2.89 kJ mol–1 in water and –0.75 kJ mol–1 in glycerol. The formation of micelles of acylcarnitine chlorides in ethylene glycol is important in terms of a better understanding of the micellization process and in terms of the metabolism of the fatty acids and their transport across biological membranes.This publication has 0 references indexed in Scilit:
