What are carbon fatty acids?
Generally, a fatty acid consists of a straight chain of an even number of carbon atoms, with hydrogen atoms along the length of the chain and at one end of the chain and a carboxyl group (―COOH) at the other end. It is that carboxyl group that makes it an acid (carboxylic acid).
What does C14 0 mean?
Tetradecanoic acid. Other names. C14:0 (Lipid numbers) Identifiers. CAS Number.
What does the terminology C18 2 mean?
Other names. cis,cis-9,12-Octadecadienoic acid. C18:2 (Lipid numbers) Identifiers. CAS Number.
How are fatty acids named?
Fatty acids are fairly long linear hydrocarbon chains with a carboxylic acid group at one end. Fatty acids are named based on the number of carbon atoms and carbon-carbon double bonds in the chain.
How do you label fatty acids?
For omega nomenclature you need to know 3 things:
- Number of carbons in the fatty acid.
- Number of double bonds.
- Number of carbons from the methyl end (aka Omega end) to the first carbon in the double bond closest to the methyl end.
How are fatty acids classified?
Fatty acids are classified according to the presence and number of double bonds in their carbon chain. Saturated fatty acids (SFA) contain no double bonds, monounsaturated fatty acids (MUFA) contain one, and polyunsaturated fatty acids (PUFA) contain more than one double bond.
What are examples of polyunsaturated fatty acids?
The two types of polyunsaturated fats are omega-3 and omega-6 fatty acids. Omega-3 fatty acids are found in foods from plants like soybean oil, canola oil, walnuts, and flaxseed. They are also found in fatty fish and shellfish as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
What are the 9 saturated fatty acids?
Propionic (C3)
What does C18 1 mean?
Saturated fatty acids In common nomenclature, the suffix is usually -ic. C18:0 means that the carbon chain of the fatty acid consists of 18 carbon atoms and there are no (zero) double bonds in it, whereas C18:1 describes an 18-carbon chain with one double bond in it.
How do you nomenclature fatty acids?
The common name of the fatty acid we have been naming in this section is oleic acid. The table below gives the common names and food sources of some common fatty acids….Common Names.
| Omega Name | Common Name |
|---|---|
| 18:1 (n-9) | Oleic Acid |
| 18:2 (n-6) | Linoleic Acid |
| 18:3 (n-3) | Alpha-linolenic Acid |
| 20:4 (n-6) | Arachidonic Acid |
What is fatty acid profile?
The fatty acid profile largely determines properties and uses of a vegetable oil (see Table 3.4). Optimum applicability requires tailored fatty acid profiles. High erucic acid contents are detrimental for food quality.
