CHDH (Choline Dehydrogenase) is a crucial enzyme involved in choline metabolism, converting choline into betaine. This conversion aids the production of acetylcholine, an essential neurotransmitter, and helps regulate homocysteine levels, which is vital for cardiovascular health. CHDH activity impacts choline availability, influencing liver function, brain development, and nervous system health. Studying CHDH can provide valuable insights into nutritional requirements and interventions for metabolic disorders.
