Monounsaturated fatty acids contain one double bond along the chain. The term "unsaturated" indicates that fewer than the maximum possible number of
hydrogen atoms are bonded to each carbon in the molecule. The number of double bonds is indicated by the generic name - monounsaturated for molecules
with one double bond or polyunsaturated for molecules with more than one double bond. Monounsaturated fatty acid can be converted to the corresponding
saturated acid by a procedure called catalytic hydrogenation.
Scientists believe that increased consumption of monounsaturated fats, for example eating more nuts, is beneficial in lowering LDL cholesterol
and lowering the risk of coronary heart disease, especially if monounsaturated fats are used to substitute for saturated fats and refined sugars.
