13 C spin lattice relaxation times ( T 1 ) of glyceryl trivalerate have been measured as a function of concentration in CDCl 3 solutions. The T 1 values indicate that there is a gradient in the rate of rotational motions around the CC bonds in the hydrocarbon chains, the rate increasing towards the methyl groups. Examination of T 1 values as a function of concentration suggests that glyceryl trivalerate does not aggregate in CDCl 3 solutions, unlike other lipids with long hydrocarbon chains. It is concluded that the length of the hydrocarbon chain plays a dominant role in determining the aggregation behaviour of lipids in solution.
