Structure of triglycerides, saturated vs unsaturated fats
Triglycerides have a glycerol backbone which is bonded with three fatty acid chains. Gylcerol is an organic compound. To form fats, a fatty acid attaches to each of glycerol's 3 carbons and forms ester bonds via oxygen atoms. The fatty acids that attach to glycerol are made up of a long chain of hydrocarbons with a carboxyl group attached at the end. To form ester bonds with glycerol, the OH in the fatty acid's carboxyl group bonds with the H in the glycerol to release a water molecule (dehydration synthesis).
Saturated fats
Saturated fats have the maximum amount of hydrogens possible. They do not contain double bonds in the middle of the chain/within the hydrocarbon groups. They are usually solid at room temperature
Unsaturated fats
Unsaturated fats contain double bonds within the hydrocarbon groups. This means that the amount of hydrogen they contain is not maximized. They are usually liquid at room temperature. There are two types of unsaturated fats: monounsaturated fats and polyunsaturated fats.

Healthy fat consumption
The body requires some fat in the diet because without it, it cannot preform the functions that essential fats such as Omega-3 fatty acids allow. Without fats, the body would also lack a stable long term energy source and the insulation it provides. One healthful approach to including fat in our diet is limiting fried food intake and focusing on moderate consumption of healthy fats.
