- 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

分子式
吸収
- 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。
生合成
- acetyl-CoA→hydroxymethyl-glutaryl coenzyme A(HMG-CoA)-(HMG-CoA reductase)→mebaronate→・・・→コレステロール
- →コレステロールの生合成
体内循環
- 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)。
- 肝臓は血液循環からHDL, IDL, VDLを受容体を介して取り込む
排泄
- 肝臓でコレステロールは胆汁酸に変換され、胆汁として排出される
