Summary Introduction
To determine:
The reason for the differences in the melting point of olive oil and soybean oil.
Introduction:
Oils are dietary lipids that are derived from plants such as corn, soybeans, or peanuts. They are also triglycerides that formed from the condensation reaction of three fatty acids with a glycerol molecules. Oils are liquid at room temperature.
