胆固醇的中间氧化产物，主要在肝脏中代谢。Cholestenone 在膜中具有很高的流动性，会影响胆固醇的翻转和外排。Cholestenone 可能会导致细胞长期功能缺陷。 Cholestanone is a cholesterol metabolite that has a keto group in place of the 3-hydroxy group on cholesterol. It decreases TGF-β-induced Smad2 phosphorylation and TGF-β expression and prevents inhibition of DNA synthesis by TGF-β in Mv1Lu cells. Increased fecal excretion of cholestenone is correlated with an increased risk of colorectal cancer. Cholestenone reduces serum cholesterol levels in a variety of animal models but is toxic to rats due to induction of hypertrophy and reduction in the activity of the adrenal gland. It has been used as synthetic intermediate in the synthesis of steroids.
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系，公式为：
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
摩尔浓度计算公式
用本工具协助配置特定浓度的溶液，使用的计算公式为：
开始浓度 x 开始体积 = 最终浓度 x 最终体积
稀释公式
稀释公式一般简略地表示为：C1V1 = C2V2 ( 输入 输出 )
