Description: (±)-α-Bromo-γ-butyrolactone 97
Catalog Number: (BOSSBS-3899R-A680)
Supplier: Bioss
Description: Has a role in maintaining calcium homeostasis. catalyses the NADPH-dependent 24-hydroxylation of calcidiol (25-hydroxyvitamin D(3)) and calcitriol (1-alpha,25-dihydroxyvitamin D(3)). The enzyme can perform up to 6 rounds of hydroxylation of calcitriol leading to calcitroic acid. It also shows 23-hydroxylating activity leading to 1-alpha,25-dihydroxyvitamin D(3)-26,23-lactone as end product.
