包装 50, 250 mg in poly bottle
1 g in poly bottle 生化/生理作用 Pterine consists of pyrazine and pyrimidine with substitutions in keto and amino group. Pterine is present in all organisms including cyanobacteria. It acts as a cofactor for redox enzymes and serves as a precursor for folic acid synthesis. Pterine from the butterfly wings absorb light and elicit incoherent scattering. Pterine induces alterations in DNA by hydroxylation of deoxyguanosine. 其他说明 Tandem Mass Spectrometry data independently generated by Scripps Center for Metabolomics is available to view or download in PDF.
