Fatty acids are made from carbon, hydrogen and oxygen. Fatty acids are constructed from the chemical elements carbon, oxygen and hydrogen. Fatty acids can be divided into a carboxylic acid head groupâhence fatty acidâlinked to a long chain of carbon atoms. The bond between the carbon atoms stores a large amount of biochemical energy and is very stable, allowing fats to be an efficient long-term store of energy in your body.
Any of a large group of organic acids, especially those found in animal and vegetable fats and oils. Fatty acids are mainly composed of long chains of carbon atoms linked to hydrogen atoms. A fatty acid is saturated when the bonds between carbon atoms are all single bonds. It is unsaturated when any of these bonds is a double or triple bond.
