The parital hydrogenation of oils and fats reduces the cis double bonds in fats to give them a more solid form at room temperature. As the reduction process takes place at high temperatures, there is thermal isomerization of some of the cis bonds to their trans form.
Margarine is produced by the hydrogenation of vegetable oils.
Oxidation: rancidity , corrosion ,Oxidation reactions occur in the batteries, we use daily. Oxidation of Fruit and Vegetable Slices ,Decay of living matter by atmospheric oxidation, into CO2 and H2O reduction (i'm not so sure! but still): FUELING THE SPACE SHUTTLE. , COMBUSTION AND EXPLOSIONS , EXPLOSIVES , The primary process of reducing ore to produce metals is discussed in the article on Smelting.
By the process of Hydrogenation.

Ethanol can be a biofuel if it is obtained from vegetable matter. It can also be produced by the hydrogenation of ethylene in a refinery or chemical plant.
One of the effects of hydrogenating vegetable oil is to raise the melting temperature, making it a solid instead of a liquid at room temperature.
Unsaturated vegetable oils tend to be liquid at room temperature, but they can also be 'hardened', through a chemical process called hydrogenation, to make them solid at room temperature.
vegetable ghee is more saturated then vegetable oil. More double bonds are present in oil compared to vegetable hence oil is better than ghee. More details can be found in hydrogenation of fats.
