The difference between dietary fats lies in their chemical structure. All fats are made up of a chain of carbon atoms that are linked -- or bonded -- to hydrogen atoms. Insaturated fats, the carbon atoms are totally covered, or "saturated," with hydrogen atoms. This makes them solid at...
Quick chemistry lesson: Saturated fats are made up of fatty acid chains that are saturated with hydrogen molecules (hence the name). Their structure makes it so that many chains can line up with very little space between them. Because the saturated fat molecules are so tightly packed together,...
Fats made up of saturated fatty acids are solid at room temperature. You can also see that oleic acid is not saturated. Two of the carbons are connected by a double bond, and two of the hydrogens are missing. This fatty acid is unsaturated. Fats that have a lot of oleic acid in ...
Fats are organic molecules made up of carbon and hydrogen elements joined together in long chains called hydrocarbons. These molecules can be constructed in different ways, which creates different types of fat and their unique properties. The molecular configuration also determines whether fats will be...
Fats and oils have been discussed in several previous chapters. The major portions of fats and oils are made up of fatty acid esters of glycerol. Edible fats and oils come from both plant and animal sources and have important functional and nutritional properties in foods. Certain components of...
The research team found,at the same time,that after assessing the effect of polyunsaturated fats made up of larger amounts of fish and vegetable oils and olive oil,these products are associated with a lower risk of suffering depression. The report,published in the online journal PLOS ONE,noted...

Lipids are made up of the monomers fatty acids and glycerol. Lipids and their monomers are composed of the chemical elements carbon, hydrogen, and oxygen. Fats provide many functions for the human body and its cells. Additionally, fats can be broken up into their own categories where different...
