Fatty Acids脂肪酸
In biochemistry, a fatty acid is a carboxylic acid with a long aliphatic chain, which is either saturated or unsaturated. Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, from 4 to 28. Fatty acids are usually not found in organisms in their standalone form, but instead exist as three main classes of esters: triglycerides, phospholipids, and cholesteryl esters. In any of these forms, fatty acids are both important dietary sources of fuel for animals and they are important structural components for cells.
在生物化学中，脂肪酸是一种具有长碳链的羧酸，该碳链可以是饱和的也可以是不饱和的。大多数天然存在的脂肪酸具有无分支、碳原子数为偶数的链，碳原子数范围从4到28。脂肪酸通常不会以独立形式存在于生物体中，而是以三种主要的酯形式存在：三酰甘油、磷脂和胆固醇酯。无论以何种形式存在，脂肪酸都是动物重要的能量来源，同时也是细胞的重要结构成分。 |
