I'm not sure exactly what the term simple fats refers to but I am guessing you are referring to is the fats the body needs to function. By this I mean the fats included in the structure of cells and many necessary body organs. I may be wrong but at least its a good guess.
palmitic acid, stearic acid
acetic acid
Palmitic acid is a common dietary saturated fatty acid found in various foods like meat, dairy, and palm oil. It is known for its role in promoting atherosclerosis when consumed in excess.

Dietary lipids are a concentrated energy source, providing nine calories per gram. They are essential for absorbing fat-soluble vitamins (A, D, E, and K) and serving as building blocks for cell membranes. Lipids also play a role in hormone production and insulation for body organs.
Stearic
Omega 3 fatty acids - found in abundance in certain fish, such as salmon, tuna and others, as well as in flax seed oil - are heart healthy dietary lipids. Olive oil is a monounsaturated fatty acid which is also a heart healthy dietary lipid.
No, it's not a fatty acid or essential fatty acid.
Propionic acis is not a fatty acid.
Lipases are digestive enzymes that hydrolyze molecules of fat into fatty acid and glycerol molecules in the small intestine. They help break down dietary fats for absorption and utilization in the body.
A monounsaturated fat
The difference between a hydrocarbon and a fatty acid is that a fatty acid is a hydrocarbon chain with a carboxylic acid head.
