Oxidation Effects on Tetrahydropterin Metabolism [PDF]
The susceptibility of tetrahydropterins to oxidation was investigated in vitro and related to in vivo metabolism. At physiological pH, tetrahydrobiopterin (BH4) was oxidized, with considerable loss of the biopterin skeleton, by molecular oxygen.

Folate Stability During Food Processing and Different Cooking Methods
, 2010 Biološki aktivni oblici folata su reducirani metaboliti folne kiseline - tetrahidrofolati. Tetrahidrofolati sudjeluju u reakcijama sinteze purina i pirimidina, temeljnih gradivnih sastavnica deoksiribonukleinske kiseline, dok je 5-metiltetrahidrofolat ...

Stability of labile folate is enhanced by binding milk folate-binding protein
, 2000 Folic acid is the parent of a number of derivatives that are vitamins, essential for DNA and amino acid synthesis. Almost all naturally occurring folates are tetrahydro-folates, which are susceptible to oxidation in air, with loss of vitamin activity ...

Folate: metabolism, biochemistry and role in disease processes.
, 2008 Folate is a water-soluble B-vitamin that holds a key position in cell growth and development. By DNA synthesis and mitosis, as well as DNA methylation and regulation of gene expression, folate is deeply involved in cell life.
