※ 引述《xenosdk (xenosdk)》之銘言： : CE is less reactive, therefore it is natural for cells to store their : cholesterol in the esterified form (mainly in the lipid droplet). : Free Cholesterol is prone to oxidation and peroxidation, : which are essentially toxic to the cells. On top of that, oxysterols are : also important regulators in many pathways, so it is likely for cells : to prevent unecessary oxysterol formation. : These are probably considered to be the main reasons for the esterification : of cholesterol. To support that, recent study also showed that accumulation : of free cholesterol will lead to apoptosis. 應該沒有很難翻 ===== less reactive adj. 不易反應、化學性質不活潑 cholesterol n. 膽固醇 esterify v. 酯化 esterified adj. 被酯化的 form n. 型態 lipid droplet n. 脂質包覆的小油滴 oxidation n. 氧化反應 peroxidation n. 過氧化反應 essentially adv. 基本上 toxic to the cells 對細胞來說是有毒的 On top of that ph. (除了以上所述、除此之外)??? oxysterols n. 氧化型態的膽固醇 regulators n. 調節因子 * pathways n. (路徑) ← 確實的說是指什麼? * it is likely for cells to 這裡應該可以翻成「細胞會盡量去...」 esterification n. 酯化反應 accumulation n. 累積 apoptosis n. 細胞凋零反應、細胞自殺 ===== 不確定的地方請高手補完吧~ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.128.67.242
