什么是脂肪酒精?
脂肪醇通常是一种高分子量,是源自脂肪和油脂的直链初级酒精。脂肪酒精的链长随源而变化。一些商业上重要的脂肪醇包括Lauryl,硬脂醇和油基醇。这些脂肪醇是无色的油性液体或蜡质固体,如果有杂质,可能会以黄色出现。通常,脂肪酒精中的碳原子数量均匀。通常,它在末端碳原子上具有单个酒精基团。
有些是不饱和脂肪醇,而其他人are branched structures. These fatty alcohols are very important in the industry. Similar to fatty acids, fatty alcohols are often referred to generically with the number of carbon atoms in the molecule, e.g. C-12 alcohol has 12 carbon atoms.
什么是脂肪酸?
脂肪酸是羧酸,其中含有饱和或不饱和的长脂肪型碳链。这意味着脂肪族链可能也可能不会包含碳原子之间的双键。顺式和反式脂肪酸是两种不饱和脂肪酸的形式。
Cis fatty acids are carboxylic acids containing long aliphatic carbon chains having the two hydrogen atoms attached to a double bond on the same side of the carbon chain. We name this the “cis configuration of unsaturated fatty acids.”
由于氢原子位于碳链的同一侧,因此会导致链条弯曲。这限制了脂肪酸的构象自由。如果链中有许多双键,它会降低链的灵活性。此外,如果碳链沿线有更多的顺式配置,它使该链条以最容易接近的构象弯曲。例子包括顺式烯酸和顺式核酸。
Trans fatty acids are carboxylic acids containing long aliphatic carbon chains having the two hydrogen atoms attached to a double bond on the opposite sides of the carbon chain. This does not cause the carbon chain to bend much. Moreover, their shape is similar to straight saturated fatty acids. Trans fatty acids are not that much common in nature as cis configuration. It forms mainly as a result of industrial production. For example, hydrogenation reactions may cause the formation of trans fatty acids.
什么是脂肪酯?
脂肪酯或脂肪酸酯是一种由脂肪酸与酒精组合形成的酯。如果此处使用的酒精成分是甘油,则根据结构,形成的脂肪酸酯可以称为一甘油酸酯,二甘油酯或甘油三酸酯。化学上,饮食脂肪是甘油三酸酯。
通常,脂肪酯是无色化合物。但是,有时,如果样品降解,它们会显得淡黄或褐色。此外,甘油三酸酯作为粉末,薄片,粗粉,颗粒或蜡质团块,油或液体出现。这些物质几乎是无味的。
脂肪醇脂肪酸和脂肪酯有什么区别?
脂肪醇通常是一种高分子量,是源自脂肪和油脂的直链初级酒精。脂肪酸是含有饱和或不饱和的长脂族碳链的羧酸,而脂肪酯或脂肪酸酯是一种来自脂肪酸与酒精的组合的一种酯。脂肪醇脂肪酸和脂肪酯之间的关键区别在于,脂肪醇含有末期醇功能组,而脂肪酸含有末端羧酸功能组,而脂肪酯含有分子中任何地方的酯功能组。

摘要 - 脂肪酒精与脂肪酸与脂肪酯
Fatty alcohols, fatty acids, and fatty esters are important lipid compounds. The key difference between fatty alcohol fatty acid and fatty ester is that fatty alcohols contain a terminal alcohol functional group and fatty acids contain a terminal carboxylic acid functional group, whereas fatty esters contain the ester functional group anywhere in the molecule.
