Lymph chylomicrons of different sizes are known to be cleared at different rates, but the underlying mechanism for this effect has not been resolved. To investigate the differences in clearance rates between small and large particles, chylomicron-like lipid emulsions labeled with radioactive triolein and cholesteryl oleate were injected into conscious rats. The clearance from plasma of small em...

A thermally stable lipase (EC 3.1.1.3.) was first identified in rice (Oryza sativa) bran, and the enzyme was purified to homogeneity using octyl-Sepharose chromatography. The enzyme was purified to 7.6-fold with the final specific activity of 0.38 micromol min(-1) mg(-1) at 80 degrees C using [9,10-(3)H]triolein as a substrate. The purified enzyme was found to be a glycoprotein of 9.4 kD. Enzym...

The radiotriolein test has been reported to be unreliable in the diagnosis of steatorrhoea. A possible explanation is provided by these studies in which labelled triolein was incubated in human gastric juice, duodenal juice, and faeces; the bond was not stable on duodenal juice.

We have previously demonstrated that lipoprotein lipase (LPL; triacylglycero-protein acylhydrolase, EC 3.1.1.34) is most likely expressed in the non-neuronal cells of the spinal cord, and glial cells may thus be the site of expression in the peripheral nervous system as well. We investigated the expression of LPL in cultured 1. 17 cells, an immortalized rat sciatic nerve Schwann cell line. The ...
