An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain.
Saturated fatty acids have no double bonds between the carbon atoms of the fatty acid chain and are thus fully saturated with hydrogen atoms.
(Wikipedia)
In an unsaturated fat there are some or at least one bonding sight that is not bonded by an additional hydrogen. In saturated fat, all bonding sights have a hydrogen attached.
Saturated means that there are no double bonds and each carbon is "saturated" with hydrogens. Unsaturated indicates the presence of double bonds and by definition an extra bond between carbons means fewer bonds are available to hydrogen.
they are long strains of hydrocarbons if the contain double bond it makes them unsaturated and it may cause some differences in physical properties
Subistitution reaction: It's a reaction where the bonds of unsaturated alkenes (double bond) can be broken down and substituted by other elements, which replace hydrogen bonds. Also they will form only a single bond.
Vegetable oil is unsaturated. Butter is saturated. Im not sure about shortening.

Saturated Fat and MAYBE Trans Fat depending on the brand.
The two basic types of fatty acids are saturated and unsaturated. A fatty acid consists of a hydrocarbon chain and a carboxyl group: CH3(CH2)nCOOH Saturated fatty acids have only single bonds between the carbon atoms in the hydrocarbon chain ie the molecule is "saturated" with hydrogen atoms and no more can be added. Unsaturated fatty acids have one or more double bonds between the carbon atoms in the hydrocarbon chain. Fatty acids with a single double bond are called monounsaturated. Fatty acids with two or more double bonds are called polyunsaturated. See:http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/F/Fats.html

There's two type of fats, unsaturated and saturated if that's what you're looking for.
