Aminolevulinic acid synthase

Aminolevulinic acid synthase (ALAS) is an enzyme that plays a crucial role in producing heme, the essential component of hemoglobin. It catalyzes the first step in the pathway that creates heme by combining specific molecules inside cells, primarily in the liver and other tissues. Proper functioning of ALAS ensures efficient heme production, which is vital for oxygen transport and various cellular processes. If ALAS activity is disrupted, it can lead to health issues like anemia or disorders related to abnormal heme synthesis.
