What are unsaturated fats and saturated fats?

Answer 1

You have one or more double bonds between carbon atoms in unsaturated fat molecules. You have no such double bonds in the structure of saturated fat molecules. You have all the single bonds between the carbon atoms.

Answer 2

Saturated fats are saturated with hydrogen atoms. This causes saturated fats to be solid at room temperature, for instance the fat on meat and coconut oil. Unsaturated fats are liquid at room temperature, corn oil and soy oil are some examples of this.
