Cholesterol is a fatty (lipid) substance carried around the body by proteins. These combinations of cholesterol and proteins are called lipoproteins. So cholesterol doesn't 'have', or contain, protein, but is chemically linked to proteins, hence the term 'lipoprotein'. There are two main types of lipoproteins:
LDL (low-density lipoprotein) is the harmful type of cholesterol.
HDL (high-density lipoprotein) is a protectivetype of cholesterol.
Cholesterol is not a carbohydrate.

Lipid
No, cholesterol is a lipid molecule itself and does not contain fatty acids. Cholesterol is a sterol molecule, while fatty acids are long hydrocarbon chains with a carboxylic acid functional group.
Cholesterol esters typically contain one fatty acid molecule esterified to a cholesterol molecule. Therefore, each cholesterol ester consists of a single fatty acid chain linked to cholesterol. The specific type of fatty acid can vary, leading to different types of cholesterol esters, but the number of fatty acids remains one per cholesterol ester.
Energy storage.
Cholesterol is the small molecule that decreases the fluidity of the plasma membrane.
cholesterol
No, cholesterol is an organic molecule because it contains carbon atoms bonded to hydrogen atoms. Inorganic molecules, on the other hand, typically do not contain carbon-hydrogen bonds.
Vitamin D is produced in the skin, on exposure to UV (ultravoilet) radiation, from a modified cholesterol molecule; necessary for normal bone growth and function.
Cholesterol is the most important steroid molecule because it serves as a precursor for the synthesis of other essential steroids in the body, including hormones like cortisol, estrogen, and testosterone. Additionally, cholesterol is a key component of cell membranes and plays a crucial role in maintaining cell structure and function.
