Lipids- Triglycerides

Triglycerides are basically used in the body to store fats. They are found in some levels in your blood stream and are also minor components of cell membranes. When found in too high of levels in your body they can be dangerous to your health. Triglycerides are composed of a glycerol molecule and three fatty acids. There are two types of fats; saturated fats and unsaturated fats. Saturated fats have a single bond between the carbons plus a hydrogen atom. Saturated fats are the fats that are most unhealthy for you and include substances made from animal products such as lard. There are no double bonds in saturated fats because of the hydrogen atoms. Unsaturated fats have one or more double bonds between carbons.  Unsaturated fats are healthier fats and are mostly plant derived such as peanuts or vegetable oil.
