Which substance, found in animal fats and dairy products, is essential for cell membrane development but can lead to heart disease in excess?

Cholesterol is a waxy, fat-like substance that is vital for the formation of cell membranes, which play a crucial role in maintaining the structure and function of cells. It is also involved in producing hormones and vitamin D, as well as aiding in the metabolism of fat-soluble vitamins. While cholesterol is necessary for various bodily functions, an excess of it in the bloodstream can lead to the development of plaque in the arteries, increasing the risk of heart disease and other cardiovascular issues. This relationship highlights the importance of maintaining balanced cholesterol levels through diet and lifestyle choices.

Other substances listed, such as glucose, triglycerides, and proteins, while important for various bodily functions, do not specifically link to cell membrane development in the same way cholesterol does, nor are they directly associated with the risk of heart disease in the same context as cholesterol.
