Myristoyl-L-carnitine is primarily used in research and development within the fields of biochemistry and nutrition. It plays a role in studying lipid metabolism and energy production, particularly in the context of fatty acid transport across mitochondrial membranes. This compound is also utilized in investigations related to metabolic disorders, such as deficiencies in carnitine or impaired fatty acid oxidation. Additionally, it serves as a valuable tool in exploring the mechanisms of muscle function and cellular energy dynamics, aiding in the development of potential therapeutic strategies for conditions like obesity, diabetes, and cardiovascular diseases.
