應用
人血浆来源低密度脂蛋白用于：
- 用作无胆固醇RPMI培养基中的添加剂
- 用作缓冲液组分，以执行测定脂质过氧化测定
- 刺激肝巨噬细胞
- 用作通过平衡透析法测定帕唑帕尼未结合组分(fu%)的血浆蛋白
生化／生理作用
LDL和HDL负责在血浆中运输饮食和内源胆固醇。LDL是胆固醇和胆固醇脂的主要载体，组成了血浆中总脂蛋白的一半以上。LD通过受体介导内吞作用，被肝脏和其他组织吸收。LDL受体的胞浆结构域帮助形成被小窝，膜上的受体富集区域。受体配体结合域识别LDL上的 apo-B100，导致包被网格蛋白的囊泡形成。ATP依赖质子泵减低囊泡内的pH，导致LDL从它的受体上脱离。当网格蛋白囊泡和溶菌酶融合丧失，会导致多肽和胆固醇脂酶水解。LDL受体会循环至细胞膜。胰岛素，三碘甲状腺原氨酸和地塞米松被证明参与调解LDL受体介导的摄入。
注意
冷冻脂蛋白溶液可能导致结构或组分变化。
物理性質
低密度脂蛋白比VLDL和IDL（26nm）（MW大约3.5百万）分子质量小，而且更稠密 (~1.04)。LDL蛋白质组分是载脂蛋白 B100。LDL含有20-22%蛋白质，10-15%甘油三酯，20-28%磷酸酯，37-48%胆固醇脂和8-10%胆固醇。
外觀
含150mM NaCl和0.01%EDTA的溶液，pH7.4

Since cholesterol is a water-insoluble molecule it must be packaged for transport within the plasma. The particles that package cholesterol, cholesteryl esters, and triglycerides for transport, are called lipoproteins.
