(6R)-Tetrahydro-L-biopterin-d3 Sulfate

(6R)-Tetrahydro-L-biopterin-d3 Sulfate, also known as BH4, is a molecule that plays a crucial role in the synthesis of neurotransmitters such as dopamine, serotonin, and norepinephrine. BH4 is essential for the function of enzymes involved in the production of these neurotransmitters, including tyrosine hydroxylase, tryptophan hydroxylase, and phenylalanine hydroxylase. BH4 is also involved in the production of nitric oxide, a signaling molecule that plays a role in the regulation of blood pressure, inflammation, and neurotransmission. BH4 acts as a cofactor for the enzyme nitric oxide synthase, which produces nitric oxide from the amino acid arginine. In addition to its role in neurotransmitter and nitric oxide synthesis, BH4 has been implicated in several other physiological processes, including immune function and insulin secretion. (6R)-Tetrahydro-L-biopterin-d3 Sulfate is a deuterated form of BH4, meaning that it contains three deuterium atoms. Deuterium is a stable isotope of hydrogen that is often used in chemical research to track the movement of molecules in biological systems. The sulfate group in (6R)-Tetrahydro-L-biopterin-d3 Sulfate increases the molecule's water solubility, making it easier to dissolve in biological fluids and facilitating its transport throughout the body. Overall, (6R)-Tetrahydro-L-biopterin-d3 Sulfate is a valuable tool for studying the role of BH4 in various physiological processes.
