Cholesterol is a fat (also called a lipid) that your body needs to work properly. Too much bad cholesterol can increase your chance of getting heart disease, stroke, and other problems.
What are the characteristics of saturated triglycerides?
2nd: Saturated lipids have no double bond between molecules, which means that the fat is saturated with hydrogen molecules whereas unsaturated lipids have double bonds making them to break up the chain of hydrogen molecules, allowing the fats to liquefy at room temperature.
Which of the following is a characteristic of saturated fats which distinguishes them from unsaturated fats?
Saturated fatty acids lack double bonds between the individual carbon atoms, while in unsaturated fatty acids there is at least one double bond in the fatty acid chain. Saturated fats tend to be solid at room temperature and from animal sources, while unsaturated fats are usually liquid and from plant sources.
