Carp plasma lipoproteins under fed condition were fractionated by sequential ultracentrifugation into VLDL (d<1.006g/ml), LDL (d=1.006-1.063g/ml), and HDL (d=1.063-1.21 g/ml) according to the same density intervals of human substances. Under starved conditions only LDL and HDL were recovered, carp plasma VLDL was not recovered. The lipids concentration in carp plasma VLDL was 83.3% and its main component was triglycerides. Carp plasma lipoproteins were mainly devided into three components by polyacrylamide gel electrophoresis; Band 1, Band II, and Band III. Carp plasma HDL prepared by sequential ultracentrifugation corresponded to Band I. The lipids concentration of carp plasma HDL was about 44% both under starved and fed conditions and its main compoinent was phospholipids. Band II distributed in HDL fraction under a starved condition, however, it was recovered in LDL fraction under a fed condition. Carp plasma LDL was recogenized as a heterogeneous component and mainly distributed in the zone of Band III. Carp plasma LDL had a similar particle size to human plasma LDL. The lipids concentration in LDL under a fed condition increased about 15% when compared to that under a starved condition.
