4a-Carbinolamine tetrahydrobiopterin

Description

4a-Carbinolamine tetrahydrobiopterin, also known as 6,7-dihydrobiopterin or Q-H2BPT, belongs to the class of organic compounds known as biopterins and derivatives. These are coenzymes containing a 2-amino-pteridine-4-one derivative. They are mainly synthesized in several parts of the body, including the pineal gland. 4a-Carbinolamine tetrahydrobiopterin exists in all living organisms, ranging from bacteria to humans. 4a-Carbinolamine tetrahydrobiopterin has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make 4a-carbinolamine tetrahydrobiopterin a potential biomarker for the consumption of these foods. 4a-Carbinolamine tetrahydrobiopterin is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a significant number of articles have been published on 4a-Carbinolamine tetrahydrobiopterin.
