See, phorbols mimic the action of diacylglycerol — a fatty molecule your body uses in a number of ways, including to activate an enzyme called protein kinase C, or PKC for short.

因为佛波醇类模拟了二酰基活动，二酰基这脂肪分子在你身体里有很多作用，它能激活蛋白激酶C，简称PKC。

A study published last Wednesday in Science Advances reveals that sebum made of cholesterol, diacylglycerols and fatty acids-also known as grease-keeps ice from accumulating on polar bear hairs.

上周三发表在《科学进展》上研究表明，由胆固醇、二酰和脂肪酸（也称为脂）组成皮脂可以防止冰在北极熊毛发上积聚。

You're not getting rid of these ceramides or these diacylglycerols that build up.

你无法清除这些积聚神经酰胺或二酰。
