5α-Cholestan-3β-ol (5α-Cholestanol) is a natural sterol compound present in animal tissues, certain plants, and microorganisms, and it is also one of the important metabolites of cholesterol in the body[1]. 5α-Cholestan-3β-ol is often used to explore cholesterol metabolism pathways, the structural functions of cell membranes, and the mechanisms of related diseases[2]. Changes in the level of 5α-Cholestan-3β-ol are associated with a variety of metabolic diseases (such as familial hypercholesterolemia and cholestasis), and the detection of its content can serve as one of the potential indicators for evaluating cholesterol metabolism disorders[3]; meanwhile, 5α-Cholestan-3β-ol is also used as a standard substance for developing separation and detection methods of cholesterol and sterol compounds (e.g., high-performance liquid chromatography, gas chromatography-mass spectrometry)[4].

5α-Cholestan-3β-ol (5α-Cholestanol) 是一种存在于动物组织、某些植物及微生物中的天然甾醇类化合物，也是胆固醇在体内的重要代谢产物之一[1]。5α-Cholestan-3β-ol常被用于探究胆固醇代谢途径、细胞膜结构功能及相关疾病机制[2]。5α-Cholestan-3β-ol的水平变化与多种些代谢性疾病（如家族性高胆固醇血症、胆汁淤积症）相关，其含量检测可作为评估胆固醇代谢紊乱的潜在指标之一[3]；同时，5α-Cholestan-3β-ol也被用作标准品，用于开发胆固醇及甾醇类化合物的分离检测方法（如高效液相色谱法、气相色谱-质谱联用法[4]。
