what is a fattyb acid
In chemistry, particularly in biochemistry, a fatty acid is a carboxylic acid with a long aliphatic tail (chain), which is either saturated or unsaturated.Most naturally occurring fatty acids have a chain of an even number of carbon atoms, from 12 to 28.ipid numbers take the form C: D, where C is the number of carbon atoms in the fatty acid and D is the number of double bonds in the fatty acid (if more than one, the double bonds are assumed to be interrupted by CH 2 units, i.e. , at intervals of 3 carbon atoms along the chain).
