Common Name(s): Orotic acid,orotic acid,pyrimidine biosynthesis intermediate,cell renewal metabolic cofactor

CAS Number: N/a

DESCRIPTION

What It Does: Provides pyrimidine nucleotide precursor support for keratinocyte dna synthesis enabling efficient skin cell renewal, supports rapid wound healing from cellular proliferation substrate availability, and provides mild antioxidant protection from the uracil-like chromophore.

Why It's Used: Orotic acid precursor role in pyrimidine biosynthesis makes it a rate-limiting substrate for rapidly dividing skin cells โ€” supplementation supports the intensive nucleotide synthesis required for keratinocyte turnover (every 14-21 days) and wound re-epithelialisation.

How It Works: Orotic acid โ†’ orotate phosphoribosyltransferase โ†’ omp โ†’ ump โ†’ utp โ†’ ctp (all pyrimidine nucleotides). utp: substrate for udp-sugar biosynthesis (ha precursors); ctp: phospholipid head group synthesis (cdp-choline โ†’ phosphatidylcholine). the de novo pyrimidine pathway supplementation supports dna synthesis during cell division and ha production for skin hydration.
