性质描述: 白色结晶。熔点121℃。在高真空中8×10-2Pa升华而不分解。与麦角甾醇不同遇毛地黄皂苷不产生沉淀。在26℃时,乙醇中溶解度为28g/100ml,丙酮中25g/100ml。溶于醚,不溶于水。对光敏感,在湿空气中数日就氧。无臭、无味。维生素D是类甾醇和衍行生,是一些抗佝偻病物质的总称,其中重要的是维生互D2和维生素D3,两者作用相同。维生素D3分子式C27H44O,熔点84-85℃。
生产方法: 将麦角甾醇溶于乙醇中,在紫外光照射下开环,将反应液减压浓缩,冷冻,过滤。滤液氮,减压浓缩至干,得维生素D2粗油,经精制得成品。
用途: 主要用于防治佝偻病、骨软化症、婴儿手足搐搦症等。

一般描述

麦角钙化醇或骨化醇由麦角固醇受(紫外线)照射而产生。它是植物来源的维生素D。麦角钙化醇是维生素 D 的两种补充形式之一。它是一种脂溶性维生素。

应用

麦角钙化醇已被用作测量食品样品中维生素 D3 水平的标准。

生化/生理作用

麦角钙化醇(维生素D2)对人维生素缺乏相关疾病的治疗潜力低于胆钙化醇(维生素D3)。补充充足剂量的维生素D2可预防婴幼儿佝偻病,还能治疗成人软骨病。麦角钙化醇(维生素 D2)和 25-羟基胆钙化醇(维生素 D3)是维生素 D 的两种形式,其通过羟基化在体内活化。维生素 D2 和 D3 可广泛用于评估其对免疫和钙稳态等功能的影响的研究中。
