Summary Introduction
Introduction:
Fats, cholesterol, and oils are lipids that help in the synthesis of hormones in the body. Fats can be classified into two types, namely, saturated and unsaturated fats; saturated fats are usually obtained from animal sources and are generally solid at room temperature, while unsaturated fats are healthy and do not promote heart diseases.
