Answer:
Carbohydrates covalently linked to proteins (glycoproteins) or lipids (glycolipids) are also a part of cell membranes, and function as adhesion and address loci for cells. The Fluid Mosaic Model describes membranes as a fluid lipid bilayer with floating proteins and carbohydrates.
Explanation:
Low-density lipoproteins (LDL) are the principal transport vehicle for cholesterol in the blood.
The body needs cholesterol, a waxy, fatty molecule, in the proper proportions for overall health. High blood cholesterol is a disorder that can result from unfavorable cholesterol levels. Low-density lipoprotein (LDL), also known as "bad" cholesterol, is the type of lipoprotein that carries cholesterol in your blood.
Cholesterol is primarily brought on by consuming fatty foods, failing to exercise regularly, being overweight, smoking, and using alcohol. Moreover, it can run in families. By consuming a healthy diet and increasing your physical activity, you can lower your cholesterol. Some folks also require medication. The majority of the cholesterol in your body is LDL (low-density lipoprotein), also referred to as "bad" cholesterol. Your risk of heart disease and stroke increases if your LDL cholesterol levels are high.

A. Organic compounds - C₃N₂H₄ , C₆H₅F and C₁₂H₂₂O₁₁
Organic compounds are compounds which have Carbon except few compounds such as carbon dioxide, cyanide. Other than Carbon, other elements also present such as Hydrogen, Oxygen and Nitrogen. But Carbon is considered as the main element of organic compounds.
B. Inorganic substances - AIBr₃ , CrO₃ and <span>H</span>₂<span>O</span>₂
Inorganic substances are the compounds which do not own C-H bonds. Most inorganic compounds do not have carbon as their element except few. (Cyanides, carbon dioxide, carbon monoxide and so on are considered as inorganic although they have carbon).
