油並無法容易溶於水裡,因此當脂肪從我們身體的血液循環系統時,便需要依靠蛋白質的輔助,合體成為脂蛋白(Lipoprotein),才能方便於血液中流動行走。792Please respect copyright.PENANASSaBQywjaD

(圖2)根據密度及體積,脂蛋白可分成為不同種類。792Please respect copyright.PENANAoeiEwhRKoy

Low Density Lipoprotein(LDL)主要負責從肝臟把油脂傳送到各器官,而血液LDL含量長期高企的話,患上心臟病或中風的機會亦會高企,因此經常被冠稱為壞膽固醇。792Please respect copyright.PENANAk6WRgqEnux
792Please respect copyright.PENANAKcEGoYy63y
而當細胞尤其是肝臟細胞內的膽固醇過多的話,便會以High Density Lipoprotein(HDL)的形式排出細胞外。792Please respect copyright.PENANAgzU1xi5xUP
細胞內含有過多膽固醇的話便會觸發細胞進行死亡的機制,基於HDL能把它們帶出細胞外,避免壞事發生,因此亦被稱之為好膽固醇。792Please respect copyright.PENANArCXOyl7Nor

(圖3)細胞可從外間直接攝取膽固醇,又或者是從其他原料自行製作膽固醇。792Please respect copyright.PENANAPRIRWINnZd

降膽固醇藥Statin能夠抑制其中一隻參與製作膽固醇過程的酶素,導致膽固醇的製作無法順利完成。792Please respect copyright.PENANATwkRfNIQaS
792Please respect copyright.PENANABlP6pwZda3
而細胞在藥物的誤導下,以為是自己因為吸收不足夠的LDL,所以無法製作膽固醇,因此便會增大吸收外間LDL的能力,得出的結果就是把血液裡的壞膽固醇含量大幅度下降。792Please respect copyright.PENANALdFbP5eXNq
792Please respect copyright.PENANAstPpgzIKsG
能降低血液LDL含量固然是一件好事,畢竟血液LDL含量與心臟病中風等疾病有著密切的關聯。792Please respect copyright.PENANAYxWEy4HmQF
但亦有一些統計數據指出服用Statin會增加患癌風險,其機制現時尚未能搞得清楚。792Please respect copyright.PENANAhTaDZCWQFD
792Please respect copyright.PENANAlq7s1DjvWl
Statin藥物所抑制的製作膽固醇的機制,箇中亦包含其他有用的有機物及代謝物製作。792Please respect copyright.PENANA1qeEYFLpWr
干涉到那些有機物的製作會否促成癌症生長,還需要大量的研究作出探討。792Please respect copyright.PENANAfV6o0m0yYM
