Detailed explanation-1: -Saturated fats contain only single bonds between carbon atoms. All the carbons are bonded to hydrogens, and there are no carbon double bonds. Generally, saturated fats come from animals (but also some tropical oils like coconut and palm oil), and they are solid at room temperature.

Detailed explanation-2: -Fatty Acids Lipids consist only or mainly of carbon, hydrogen, and oxygen. Both fats and oils are made up of long chains of carbon atoms that are bonded together. These chains are called fatty acids.

Detailed explanation-3: -Cholesterol esters, triacylglycerols and free (unesterified) cholesterol tend to be the most abundant simple lipids.

Detailed explanation-4: -If you look at palmitic acid and stearic acid chains, you can see that the carbon chains are completely and evenly filled with hydrogen atoms. In other words, the chains are saturated with hydrogen. Fats (triglycerides) that contain palmitic acid and stearic acid are therefore known as saturated fats.
