5-Aminolevulinic acid (5-ALA) is a naturally occurring compound in the body that plays a crucial role in producing heme, a component of hemoglobin in red blood cells. Apart from its biological importance, 5-ALA is used in medical applications, particularly in photodynamic therapy, where it helps target and treat certain types of cancer. When exposed to specific light, 5-ALA transforms into a substance that can destroy cancerous cells. Additionally, it has applications in dermatology for treating skin conditions and improving the appearance of the skin.
