短释义：
Cholesterol is a product of the liver, excreted through bile into the digestive tract. The first notice of cholesterol was in 1769, when a French researcher found it in gallstones. Then, in the early 19th Century the chemical was named “cholestrine,” from the Greek words for bile (chole) and solids (stereos), plus the chemical suffix -ol. Scientists have noted the role of cholesterol in heart attacks and other health problems, a situation that can be regulated through diet or medications.
胆固醇是动物组织中天然存在的类固醇。它对健康的细胞膜和其他功能很重要，但其蜡质成分使其具有危险，因为高浓度可能会积聚并阻塞动脉。

胆固醇是肝脏的产物，通过胆汁排泄到消化道。胆固醇的首次发现是在 1769 年，当时一位法国研究人员在胆结石中发现了胆固醇。然后，在 19 世纪初，这种化学物质被命名为“cholestrine”，源自希腊语中胆汁 (chole) 和固体 (stereos) 的意思，加上化学后缀 -ol。科学家们已经注意到胆固醇在心脏病和其他健康问题中的作用，这种情况可以通过饮食或药物来调节。
文学例句：

坚持服用，卵磷脂可以部分并缓慢地消除循环系统中现有的胆固醇沉积物。

词源：
cholesterol (n.)white, solid substance present in body tissues, 1894, earlier cholesterin, from French cholestrine (Chevreul, 1827), from Latinized form of Greek khole “bile” (from PIE root *ghel- (2) “to shine,” with derivatives denoting “green, yellow,” and thus “bile, gall”) + steros “solid, stiff” (from PIE root *ster- (1) “stiff”). So called because originally found in gallstones (Conradi, 1775). The name was changed to the modern form (with chemical suffix -ol, denoting an alcohol) after the compound was discovered to be a secondary alcohol.Related entries & more

胆固醇（n.）白色，存在于身体组织中的固体物质，1894年，早期的胆固醇，来自法语cholestrine（Chevreul，1827），来自希腊语khole“胆汁”的拉丁化形式（来自PIE根*ghel-（2）“发光” ，”，派生词表示“绿色、黄色”，因此表示“胆汁、胆汁”）+ steros“固体、坚硬”（来自 PIE 根 *ster- (1) “僵硬的”）。如此称呼是因为最初发现于胆结石中（Conradi，1775）。在发现该化合物是仲醇后，该名称更改为现代形式（带有化学后缀 -ol，表示醇）。相关条目及更多
