1. An attempt was made to purify lipoprotein lipase (LpL) from the flight muscle of the migratory locust based on affinity for heparin, which is known to avidly bind mammalian LpL. 2. However, locust LpL appeared to completely lack this property, which indicates that the suggested membrane-binding of locust LpL is very different from that of mammalian LpL: a heparin-like glycosaminoglycan is not involved. 3. Since locust LpL lacks heparin affinity, other purification methods were assayed. Solubilization of locust LpL was obtained by the detergent Tween 20. 4. Though both anion and cation exchange chromatography resulted in the complete loss of enzyme activity, partial purification of locust LpL was achieved by gel filtration chromatography.

UI MeSH Term Description Entries
D008071 Lipoprotein Lipase An enzyme of the hydrolase class that catalyzes the reaction of triacylglycerol and water to yield diacylglycerol and a fatty acid anion. The enzyme hydrolyzes triacylglycerols in chylomicrons, very-low-density lipoproteins, low-density lipoproteins, and diacylglycerols. It occurs on capillary endothelial surfaces, especially in mammary, muscle, and adipose tissue. Genetic deficiency of the enzyme causes familial hyperlipoproteinemia Type I.

D006110 Grasshoppers Plant-eating orthopterans having hindlegs adapted for jumping. There are two main families: Acrididae and Romaleidae. Some of the more common genera are: Melanoplus, the most common grasshopper; Conocephalus, the eastern meadow grasshopper; and Pterophylla, the true katydid.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
