产品说明 应用 DL-同型半胱氨酸已被用于诱导Sprague-Dawley大鼠的高同型半胱氨酸血症。它还被用于研究高同型半胱氨酸血症对载脂蛋白E缺陷小鼠动脉粥样硬化的影响。 包装 10 mg in autosample vial
1, 5, 25 g in poly bottle 生化/生理作用 同型半胱氨酸是一种含巯基的氨基酸，由甲硫氨酸合成。它是一种非必需的非蛋白原氨基酸。它是甲基化循环的重要决定因素，在血浆中有四种存在形式。同型半胱氨酸的异常高水平会导致高同型半胱氨酸血症，同时会促进动脉粥样硬化。
血浆同型半胱氨酸水平升高是冠心病和癌变的危险因素；可能是肿瘤细胞生长的标志物。 其他说明 Scripps Center for Metabolomics(斯克里普斯代谢组学中心)独立生成的串联质谱数据，可以PDF格式查看或下载。 H4628.pdf 经过测试的代谢物在Scripps Center for Metabolomics(斯克里普斯代谢组学中心) METLIN 代谢物数据库中有重点介绍。更多信息请见sigma.com/metlin。 基本信息 | 线性分子式 | HSCH2CH2CH(NH2)COOH | | 分子量 | 135.18 | | Beilstein | 1721683 | | EC 号 | 207-222-9 | | MDL编号 | MFCD00004898 | | eCl@ss | 42021308 | | PubChem化学物质编号 | 24895646 | | NACRES | NA.26 |
