亚油酸和亚麻Aci的区别d

Thekey differencebetween linoleic acid and linolenic acid is that亚油酸包含两个带有顺式构型的双键，而亚麻酸包含三个带有顺式构型的双键。

Linoleic acid and linolenic acid are the two必需脂肪酸we have to obtain from the diet because our body cannot synthesize them. Moreover, these fatty acids are essential for our health.

什么是亚油酸？

Linoleic acid is an essential fatty acid having the chemical formula C₁₈H₃₂O₂。It is acarboxylic acid并有一个18碳链。碳链具有两个双键顺式配置。Therefore, we can denote it as 18:2 cis-9,12 in which 9 and 12 are the carbon atoms having the double bonds. Typically this compound occurs in nature as a triglyceride ester. Further, this compound is highly soluble in organic solvents such as acetone, benzene, ethanol, etc. The molar mass of this compound is 280.45 g/mol. It appears as a colourless oil.

When considering the uses, there are industrial applications as well as applications in the research field. In industries, we can use linoleic acid to make quick-drying oils for oil paints and varnish, as a surfactant, as an ingredient in beauty products, etc. The most important dietary sources for linoleic acid include Salicornia oil, safflower oil, and melon seed oil.

What is Linolenic Acid?

Linoleic acid an essential fatty acid having the chemical formula C₁₈H₃₀O₂。Its most common form isalpha-linolenic acid因为它是最稳定和最丰富的形式。此外，这是一种必需的脂肪酸，因此，我们需要从饮食中服用，因为我们的身体无法产生它。

Furthermore, this compound has an 18-carbon chain with 3 double bonds in the cis configuration. Therefore, we can denote it as 18:3 cis-9,12,15 in which 9, 12 and 15 are the carbon atoms having double bonds. Its molar mass is 278.43 g/mol. The important dietary sources of linolenic acid include kiwifruit seed, Chia, Perilla, Rapeseed, Soybean, etc.

What is the Difference Between Linoleic Acid and Linolenic Acid?

Linoleic acid is an essential fatty acid having the chemical formula C₁₈H₃₂O₂while linoleic acid an essential fatty acid having the chemical formula C₁₈H₃₀O₂。However, the key difference between linoleic acid and linolenic acid is that linoleic acid contains two double bonds with cis configuration while linolenic acid contains three double bonds with cis configuration.

According to the configurations in these compounds, we can denote linoleic acid as 18:2 cis-9,12 and linolenic acid as 18:3 cis-9,12,15. When considering the dietary sources, the most important dietary sources for linoleic acid include Salicornia oil, safflower oil, melon seed oil, etc. The important dietary sources of linolenic acid include kiwifruit seed, Chia, Perilla, Rapeseed, Soybean, etc.

概括– Linoleic Acid vs Linolenic Acid

Linoleic acid is an essential fatty acid having the chemical formula C₁₈H₃₂O₂while linoleic acid an essential fatty acid having the chemical formula C₁₈H₃₀O₂。亚油酸和亚麻酸之间的关键区别在于亚油酸包含两个双键，而亚麻酸含有三个带有顺式构型的双键。
