Which hormone is characterized by an increase in protein synthesis and mobilization of stored fat?

The hormone that is characterized by an increase in protein synthesis and mobilization of stored fat is growth hormone. This hormone plays a crucial role in various metabolic processes within the body. Growth hormone stimulates the liver to produce insulin-like growth factor 1 (IGF-1), which promotes protein synthesis, leading to muscle growth and repair. Additionally, growth hormone aids in the breakdown of fat stores, allowing the body to use them for energy, thereby reducing fat mass.

Growth hormone is essential not only for growth and development during childhood and adolescence but also for maintaining muscle mass and fat metabolism in adults. Its ability to enhance protein synthesis and mobilize stored fat makes it particularly relevant in the context of athletic performance and recovery, as well as in body composition changes.
