Lipolysis

Definition

Lipolysis is the process by which the body breaks down fats into fatty acids and glycerol, which can then be used by the body for energy.

Scientific / Technical Definition

Lipolysis is the metabolic pathway through which lipid triglycerides are hydrolyzed into glycerol and free fatty acids, predominantly in adipose tissue. This process is catalyzed by enzymes such as hormone-sensitive lipase and occurs predominantly under hormonal responses like adrenaline or glucagon, especially during fasting or exercise.

Benefits

• Provides energy for the body during fasting or prolonged exercise
• Helps in the reduction of fat stores
• Supports metabolic health

Examples

• During exercise, the body enhances lipolysis to support energy needs.
• In a fasting state, lipolysis increases to supply energy to vital organs.

Additional Information

• Effects: Lipolysis helps maintain energy homeostasis and is crucial in managing body weight and preventing obesity-related conditions.
