https://simple.wikipedia.org/wiki/Fatty_acidFatty acids are aliphatic monocarboxylic acids derived from, or contained in, an animal or vegetable fat, oil, or wax. Natural fatty acids commonly have a chain of four to 28 carbon atoms (usually unbranched and even numbered), which may be saturated or unsaturated. This would include acetic acid, although this is not usually considered a fatty acid (not a lipid).

- https://en.wikipedia.org/wiki/Essential_fatty_acid
Essential fatty acids, or EFAs, are fatty acids that humans and other animals must ingest because the body requires them for good health but cannot synthesize them.
The term "essential fatty acid" refers to fatty acids required for biological processes but does not include the fats that only act as fuel. Essential fatty acids should not be confused with essential oils, which are "essential" in the sense of being a concentrated essence.Wikipedia · Nội dung trong CC-BY-SA giấy phép - https://en.wikipedia.org/wiki/Fatty_acid_metabolism
- Fatty acid metabolism consists of various metabolic processes involving or closely related to fatty acids, a family of molecules classified within the lipid macronutrient category. These processes can mainly be divided into catabolic processes that generate energy and anabolic processes where they serve as building blocks for other compounds. In ca...

An omega−3 fatty acid is a fatty acid with multiple double bonds, where the first double bond is between the third and fourth carbon atoms from the end of the carbon atom chain."Short-chain" omega−3 fatty acids have a chain of 18 carbon atoms or less, while "long-chain" omega−3 fatty acids have a chain of 20 or more.

Polyunsaturated fatty acids are fatty acids that contain more than one double bond in their backbone. This class includes many important compounds, such as essential fatty acids and those that give drying oils their characteristic property. Polyunsaturated fatty acids can be classified in various groups by their chemical structure: methylene-interrupted polyenes …

Butyric acid (from Ancient Greek: βούτῡρον, meaning "butter"), also known under the systematic name butanoic acid, is a straight-chain alkyl carboxylic acid with the chemical formula CH 3 CH 2 CH 2 CO 2 H. It is an oily, colorless liquid with an unpleasant odor. Isobutyric acid (2-methylpropanoic acid) is an isomer. Salts and esters of butyric acid are known as butyrates or …
