Lipid regulation refers to the processes that control the levels and types of lipids, such as fats and cholesterol, in the body. This regulation is crucial for maintaining overall health, as imbalances can lead to conditions like heart disease and obesity. The body manages lipid levels through various mechanisms, including dietary intake, metabolism, and hormonal signals. Key players in lipid regulation include lipoproteins, which transport lipids in the bloodstream, and enzymes that help break down fats. Additionally, hormones like insulin and glucagon play significant roles in lipid metabolism, influencing how the body stores and uses fats for energy.
