Lipid biology is the study of lipids, which are organic molecules that include fats, oils, and cholesterol. These substances play crucial roles in cellular structure and function, serving as key components of cell membranes and energy storage. Lipids also act as signaling molecules, influencing various biological processes. In addition to their structural and energy roles, lipids are involved in metabolism and can affect health. For example, triglycerides store energy, while phospholipids form cell membranes. Understanding lipid biology helps researchers explore conditions like obesity and cardiovascular diseases, highlighting the importance of lipids in overall health.
