DSPE-PEG(2000)-biotin 是一种对1,2-二硬脂酰-sn-甘油-3-PE进行PEG化和生物素化处理的化合物。它被广泛应用于体外和体内的脂质体输送、荧光标记纳米结构脂质载体（NLCs）的开发。此外，DSPE-PEG(2000)-biotin 也用于生成胶束，用作固定脂质体的前体，并被应用于生物层干涉测量结合实验中。当含有DSPE-PEG(2000)-biotin的脂质体内封装有多柔比星和槲皮素时，能对体外的MCF-7 adr多药耐药乳腺癌细胞产生细胞毒作用，并有效抑制MCF-7 adr小鼠移植瘤模型中的肿瘤增长。通过使用生物素偶联的FITC标记的avidin，已成功在NLCs中实现荧光标记。

1,2-Distearoyl-3-palmitoyl-rac-glycerol, a triacylglycerol, features stearic acid at the sn-1 and sn-2 positions and palmitic acid at the sn-3 position. This compound is identified in cocoa butter, lard, and cod liver oil.

1,2-Distearoyl-3-butyryl-rac-glycerol is a triacylglycerol characterized by the presence of stearic acid at the (sn-1) and (sn-2) positions and butyric acid at the (sn-3) position, notably identified within butterfat.

1,2-Distearoyl-3-arachidoyl-rac-glycerol, a triacylglycerol, comprises stearic acid at the sn-1 and sn-2 positions and arachidic acid at the sn-3 position. This compound is present in butterfat.

1,2-Distearoyl-3-oleoyl-rac-glycerol, a triacylglycerol, comprises stearic acid at the sn-1 and sn-2 positions and oleic acid at the sn-3 position. This compound is present in cocoa butter and vegetable oils.

1,2-Distearoyl-3-decanoyl-rac-glycerol is a triacylglycerol with stearic acid located at the sn-1 and sn-2 positions, and decanoic acid at the sn-3 position.
