General description
维生素A通常以视黄酯形式的存在于食物中,而视黄酯是维生素A的前体来源。视黄醇乙酸酯是黄色晶体,不溶于水。它溶于乙醇和油。
Application
视黄醇乙酸酯已被用于:
- 研究其对小鼠耳蜗发育的影响
- 作为定量测定蛋黄中抗氧化剂的内标物成分
- 作为测定血清视黄醇浓度的内标物
Biochem/physiol Actions
视黄醛、视黄醇和视黄酸是维生素 A 的醛、醇和酸形式。由于脂肪链中的不饱和键,维 a 酸的几何异构体较多。
维 A 酸也以维 A 酸酯的形式存在,如丙酸维 A 酸、醋酸维 A 酸和维 A 棕榈酸酯。视黄醇酯提供维生素 A 库,可根据需要转化为视黄醇和其他维 A 酸。醋酸视黄醇具有广泛的生物学用途。
