Creatine monohydrate is a chemical widely used in the field of sports nutrition supplements. Here is a description of creatine monohydrate and some common uses:

Description: 

•Chemical properties: Creatine monohydrate is an organic acid, creatine and water molecules combined to form a complex. It is a colorless crystalline powder that is soluble in water.

•Source: Creatine monohydrate is found in muscle and other tissues and can also be consumed through diet, such as meat and fish.

•Physiological function: Creatine monohydrate plays an important role in energy metabolism in the body. It is involved in the regeneration of adenosine triphosphate (ATP) during muscle contraction and provides the energy needed for short, high-intensity movements of muscles.

Purpose: 

1. Increase strength and explosive power: Creatine monohydrate is widely used to improve athletic performance of strength and explosive power. Since it is involved in the regeneration process of ATP, supplementation with creatine monohydrate can increase the phosphate creatine reserve of muscles, delay muscle fatigue, and thus improve strength training, repetitions, and athletic explosive power.

2. Increase muscle mass: Creatine monohydrate supplementation is also thought to increase muscle mass. By increasing the water content and protein synthesis within muscle cells, creatine monohydrate may promote muscle growth and increase the volume of muscle fibers.

3. Enhanced endurance performance: While creatine monohydrate is primarily associated with short, high-intensity exercise, some studies suggest that its supplementation may also have some positive effects on endurance performance. It can delay muscle fatigue and lactic acid accumulation, improving the durability of endurance exercise.

4. Rehabilitation and muscle injury: Creatine monohydrate supplementation has also been studied for rehabilitation and the treatment of muscle injury. It can help speed up the repair and recovery process of muscle injuries.
