Introduction to Cholesterol synthesis

Cholesterol is a structural component of cell membranes and serves as a building block for synthesizing various steroid hormones, vitamin D, and bile acids. Besides their structural role providing stability and fluidity, cholesterol also plays a crucial role in regulating cell function. The video explains the synthesis of cholesterol with all the steps and enzymes involved.
