| 生化机理 | 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。 |
| 储存温度 | -20°C储存 |
| 运输条件 | 超低温冰袋运输 |
| 产品介绍 |
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。 应用 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 Vitamin A usually occurs in food as retinyl esters, which are the pre-formed sources of vitamin A. Retinyl acetate exists as yellow crystals and is insoluble in water. It is soluble in ethanol and oils. Application Retinyl acetate has been used: to study its effects on cochlear development in mice as a component of an internal standard to quantify antioxidants in yolk as an internal standard to determine serum retinol concentration |
