... to enhanced expression of lipoprotein lipase (LPL) whereas mRNA levels of the hormone-sensitive lipase (HSL) remained almost unchanged. The resulting LPL/HSL ratio was thereby highest in fat fish, which suggests that this group of fish has not reached its peak fat storage capacity. This is not surprising...

... acids linoleic acid hormone-sensitive lipase Zonotrichia Philomachus During times of fasting or high energy demand, fatty acids are mobilized from adipocyte triacylglycerol (TRIG) stores and exported to the circulation. Inside the adipocytes, this process involves cleavage of TRIG...

..., however, has not previously been demonstrated. Employing a substrate competition assay, we have characterized the substrate specificity of hormone-sensitive lipase (HSL) from adipose tissue of the Antarctic fish Trematomus newnesi . Rates of oleic acid release from radiolabeled triolein were quantified...
