Mono-, di- and triglycerides in serum of spontaneously hypertensive and normotensive rats in relation to age.

Serum triglycerides appeared significantly lower in spontaneously hypertensive as compared to normotensive rats except in 8-week-old animals. Tri-, di and monoglycerides decreased continuously with age in the former but revealed only a transient fall in the latter. The remarkably high portion of partial glycerides (about 30% of total glycerides) in serum should be considered in all studies on lipolysis in rats.
