Question

what is the chemical nature of vegetable oil?

Answer 1

A vegetable oil is a triglyceride extracted from a plant.[1] The term "vegetable oil" can be narrowly defined as referring only to plant oils that are liquid at room temperature,[2] or broadly defined without regard to a substance's state of matter at a given temperature.[3] For this reason, vegetable oils that are solid at room temperature are sometimes called vegetable fats. In contrast to these triglycerides, vegetable waxes lack glycerin in their structure. Although many plant parts may yield oil, in commercial practice, oil is extracted primarily from seeds.

On food packaging, the term "vegetable oil" is often used in ingredients lists instead of specifying the exact plant being used, especially when the oil used is less desirable to the consumer or if a mix is used.

Animal fats tend to have more free fatty acids than vegetable oils do. Chemically, fats and oils are also called “triglycerides.” They are esters of glycerol, with a varying blend of fatty acids. ... It is also known as glycerin/glycerine.
