摘要：

The mechanism of lipid transport in octopod hemolymph was studied in Octopus tehuekhus. Three lipoproteins were detected, isolated and partially characterized by a variety of methods including TLC, ultracentrifugation and the use of radiolabelled lipids. The lipoproteins, henceforth called "LP-I", "LP-II" and "LP-III", have low, high and very high density, respectively. Cholesterol and phospholipids are mainly transported by LP-I and LP-II. Free fatty acids, hydrocarbons and esterified sterols circulate mainly associated with LP-III. Hemocyanin, the oxygen carrier pigment, also seems to play a role in the transport of lipids, being the apoprotein of LP-III. © 1990.
