Summary Introduction
To explain: The reason why plasma cholesterol needs the help of a membrane transporter to enter cells while it is soluble in lipids.
Introduction: Cholesterol is an important component of cell membranes and used to make important vitamins and hormones. We get cholesterol from various food products like eggs, milk, meat, and so on. It is also produced in our body by the liver.
