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甘油的活动，二酰基甘油这子在你的身体里有很多作用，它能激活一蛋白激酶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.

三发表在《科学进展》的一项研究表明，由胆固醇、二酰甘油和酸（也称为油）组成的皮可以防止冰在北极熊的毛发积聚。

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

你无法清除这些积聚的神经酰胺或二酰甘油。
