Lipolysis is the process by which stored fat molecules, or triglycerides, are broken down into fatty acids and glycerol. This process is essential for providing the body with energy during periods of fasting or exercise. Lipolysis is regulated by various hormones and enzymes, such as lipases, which work together to release fatty acids from fat cells for use by the body as a source of energy. Dysregulation of lipolysis can contribute to obesity and metabolic disorders. Researchers study lipolysis to better understand the mechanisms involved and develop potential treatments for obesity and related conditions.
