Oleoylcarnitine plays a significant role in lipid metabolism, particularly in the transport of fatty acids into the mitochondria for energy production. It is commonly used in research to study fatty acid oxidation and metabolic disorders, such as obesity, diabetes, and cardiovascular diseases. In clinical settings, it serves as a biomarker to assess mitochondrial function and diagnose metabolic conditions. Additionally, it is utilized in the development of therapeutic strategies aimed at improving lipid metabolism and addressing related health issues. Its application extends to nutritional studies, where it helps in understanding the impact of dietary fats on metabolic pathways.
