Structure of a fatty acid

    • Which describes the basic structure of a fatty acid?

      The elements of fatty acid structure are quite simple. There are two essential features: A long hydrocarbon chain The chain length ranges from 4 to 30 carbons; 12-24 is most common. The chain is typically linear, and usually contains an even number of carbons. A carboxylic acid group.

    • What is the structural formula for a fatty acid?

      In chemistry, particularly in biochemistry, a fatty acid is a carboxylic acid with a long aliphatic chain, which is either saturated or unsaturated. Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, from 4 to 28.

    • What are the two parts of a fatty acid?

      The fatty acid can be divided into two parts: 1. The methyl group and its chain: CH3- (CH2)p- [CH=CH]- (CH2)q-etc... This part of the molecule is water insoluble and oil-soluble. 2. The carboxyl group: -COOH It is the acid part. This part is water-soluble and does not dissolve in oil.

    • What foods are considered short chain fatty acids?

      Plant Based: The shorter-chain form of omega-3 is alpha-linolenic acid (ALA), the only omega-3 found in plants (except for some algae). Foods rich in ALA include flaxseed oil (53 percent), canola oil (11 percent), English walnuts (9 percent), and soybean oil (7 percent).

      The influence of a fatty acid’s structure on its melting point is such that branched chains and cis double bonds will lower the melting point compared with that of equiv-alent saturated chains. In addition, the melting point of a fatty acid depends on whether the chain is even- or odd-numbered; the latter have higher melting points.
