  • {Chemi
  • 作用:（1）参与形成细胞膜。 （2）胆固醇是合成胆汁酸，维生素D以及甾体激素的原料。 （3）中国正常人血清的总胆固醇量约为182.5 ±4.3毫克%。血液中胆固醇含量过高，表示胆固醇代谢可能发生障碍。冠状动脉粥样硬化患者的血清胆固醇含量往往偏高。因此临床化验上测定血清胆固醇含量将有助于诊断某些疾病。

  • 用途一:是制造激素的重要原料，并可用作乳化剂
  • 用途四:用于脑磷脂胆固醇絮状试验，维生素D、激素等药物的原料及生化研究。
  • 概述:胆固醇又称胆甾醇,一种环戊烷多氢菲的衍生物，是人体细胞各种膜相结构及神经髓鞘的重要组成成分，体重为70公斤的正常人，体内约含140克胆固醇，早在18世纪人们已从胆石中发现了胆固醇，1816年化学
  • 胆固醇价格(试剂级):更新日期 产品编号 产品名称 包装 价格 2011/08/23 69008214 胆固醇 25g 35元 2011/08/23 69008216 胆固醇 100g 135元 2011/08/23 69008279 胆固醇 1kg 1250元
  • 用途六:生化研究，脑磷脂胆固醇絮状试验。胆固醇是生物膜的主要组成部分，总脑磷脂25%左右为胆固醇。
  • 运输:参与胆固醇运输的主要是两种脂蛋白：即低密度脂蛋白(LDL)和高密度
  • 分类:胆固醇在体内有游离型和与脂类结合型(胆固醇酯) 。
  • 人体组织的胆固醇含量:体重为70公斤的正常人，体内约含140克胆固醇，其分布大致如下表。各种组织上的胆固醇含量都比较稳定，血浆胆固醇的浓度也不像脂肪和脂肪酸那样容易变化。 图1为人体各个组织的胆固醇含量
  • 所属类别
  • 用途三:人工牛黄、激素类药物的制备，亦可用作乳化剂。
  • 来源与吸收:来源： （1）外源性来自膳食中的胆固醇。（2）内源性来源于人体自身的合成。 吸收： 胆固醇在肠内吸收，主要在肝脏、皮肤及小肠粘膜等部位合成。饮食中的胆固醇以乳糜微粒的形式吸收进入血液。胆固醇的吸收还取决于摄入量，摄入量高时就会降低吸收的百分比，人吸收胆固醇在摄入高水平时低于10%。游离胆固醇被吸收后，2/3很快与脂肪酸结合而脂化形成胆固醇酯，使脂蛋白携带胆固醇的能力增加，胆固醇进入细胞后，在溶酶体内由酸性脂酶水解脱脂。部分胆固醇在细胞内转化为类固醇。多余的胆固醇部分直接排泄至肠道;部分在肝内氧化成胆汁酸随胆汁排泄。
