Answer:
C) They have 12-20 carbon atoms and an even number of carbon atoms.
Step-by-step explanation:
Fatty acid is described as Carboxylic acid that contains the structural component of lipids
fats and oils. Fatty acids are unbranched and usually have 12-20 carbon atoms evenly. They are known by their number of carbon-to-carbon double bonds present.
For saturated fatty acids, they don't have any carbon-to-carbon double bonds. Fatty acid can be classified based on the number of carbon-to-carbon, such as; monounsaturated fatty acids which have one carbon-to-carbon double bond and also polyunsaturated fatty acids which have contain more than carbon-to-carbon double bonds
Some natural fatty acid
1.)Lauric acid (C11H23COOH)
2.)Palmitic acid (C15H31COOH)
3.)Myristic acid (C13H27COOH)
4.) Linoleic acid (C17H31COOH)
5.) Arachidonic acid(C19H31COOH)
