CHDH (Choline Dehydrogenase) is a crucial enzyme involved in choline metabolism, converting choline into betaine. This process supports the production of acetylcholine, a key neurotransmitter, and helps regulate homocysteine levels, which is vital for cardiovascular health. CHDH activity affects choline availability, impacting liver function, brain development, and nervous system health. Researching CHDH can provide valuable insights into nutritional requirements and interventions for metabolic disorders.
