Fatty acids are carboxylic acids with a long hydrocarbon chain, usually straight, as the fourth substituent group on the carboxyl (-COOH)group (see functional group)that makes the molecule an acid.

脂肪酸一般由一条偶数碳原子的直链组成,整个长链上及其一端都有氢原子,另一端有一个羧基(-COOH),所以是一种羧酸。

Fats: Any organic compound of plant or animal origin that is not volatile, does not dissolve in water, and is oily or greasy. Chemically, fats are identical to animal and vegetable oils, consisting mainly of triglycerides (esters of glycerol with fatty acids).

脂肪源自动植物的不挥发、不溶于水而油腻的物质。在化学构造上,动物油和植物油是相同的,主要由甘油三酯(甘油和脂肪酸反应生成的酯)组成

Fats are found in the blood mostly in the form of free fatty acids and triglycerides

脂肪主要以游离脂肪酸和甘油三酸酯的形式存在于血液。

Fats of this group are derived from the seeds of various tropical trees and are distinguished by their narrow melting range, which is due mainly to the arrangement of fatty acids in the triacylglycerol molecules.

植物脂这类脂肪来源于各种热带树木的种子,通过其很窄的熔点范围区别开来。它的熔点范围狭窄主要是因为三酰基甘油分子在脂肪酸中的排布。

Differences in melting temperature and physical state depend on the saturation of the fatty acids and the length of their carbon chains. The glycerides may have only a few different component fatty acids or as many as 100 (in butterfat).

只有在熔点和物理状态(固体或液体)有所不同,全视脂肪酸的饱和情况和碳链的长度而定。甘油酯可能只含有少量脂肪酸,也可能多至一百种(在乳脂肪中)。

It is principally a mixture of the glycerides (see glycerol)of many fatty acids, but its minor constituents, the fat-soluble vitamin A and vitamin D, give it its importance.

主要是由多种脂肪酸甘油脂组成的混合物,含有少量但很重要的脂溶性维生素A和D。

More recently, the techniques of stereo specific analysis made possible the detailed determinations of individual fatty acid distribution in each of the three positions of the triacylglycerols of many fats.

最近立体定向分析技术使许多三酰基甘油中每个脂肪酸在三个位置的分布的测定成为可能。
