Biochimica et biophysica acta.Biochim Biophys Acta.2015 May;1851(5):598-604. doi: 10.1016/j.bbalip.2015.01.015. Epub 2015 Feb 4.
Chylomicron remnants, which carry dietary fats and cholesterol, play a role in promoting atherosclerosis. Chylomicron remnants are characterized by high cholesterol content at the surface, different from low-density lipoproteins (LDLs) containing high amounts of esterified cholesterol (CE) in the co

BACKGROUND: Familial dysbetalipoproteinemia (FD), also known as type III hyperlipoproteinemia, is a genetic dyslipidemia characterized by elevated very low density lipoprotein (VLDL) and chylomicron remnant particles that confers increased risk of cardiovascular disease (CVD). The objective of this

The Ingestion of a Fructose-Containing Beverage Combined with Fat Cream Exacerbates Postprandial Lipidemia in Young Healthy Women

… in the G100 trial, versusfour hours in the other trials, and did not return to baseline at six hours, except in the G100 trial.At four hours, the ⊿apoB48 tended to be higher in the F100 trial than in the G100 trial.Conclusions: The ingestion of a high-fructose-containing beverage with fat cream delays the clearance of chylomicron and its remnant derived from the intestine and enhances the secretion of triglyceride-rich lipoprotein particles from the liver, thereby inducing postprandial lipidemia, even in young healthy …

カイロミクロンに含まれる脂質は、血管内皮に存在するリポ蛋白リパーゼ(LPL)により分解されて脂肪酸を遊離し、コレステロールの比が高いカイロミクロンレムナントとなる。

血液循環中のVLDLの脂質は、、血管内皮に存在するリポ蛋白リパーゼ(LPL)により分解されて脂肪酸を遊離し、コレステロールの比が高いIDL、LDLとなる。

組織からはコレステロール比型が高いHDLが放出され、そのまま肝臓に取り込まれるか、IDLにコレステロールを渡すことでコレステロールの逆輸送を行っている(内因性の抗動脈硬化作用)。
