油脂 脂類
  • 脂類(英语:lipid)又稱脂質,是一類天然分子的總稱,其中包括脂肪、蠟、类固醇、脂溶性維生素(如維生素D)、單酸甘油酯、二酸甘油酯、磷脂等。它的主要生理功能包括儲存能量、構成細胞膜以及膜的訊息傳導等。如今,脂类已经被用于美容和食品工业,以及纳米技术。
  • 脂質可以廣義定義為疏水性或雙親性小分子;某些脂質因為其雙親性的特質(兼具親水性與疏水性),能在水溶液環境中形成囊泡、脂質體或膜等構造。生物體內的脂質完全或部分源自兩種截然不同的生物次單元:酮酸基與異戊二烯。
  • 脂類常被視為是脂肪的同義詞,但脂肪只是一種稱為三酸甘油脂的脂類。脂類也包括脂肪酸及其衍生物,包括單酸甘油酯、二酸甘油酯、磷脂等,也包括其他含有固醇的代謝產物,像是膽固醇。
