The bioaccessibility of folate in breads and the stability of folate vitamers during in vitro digestion.
Liu F, Edelmann M, Piironen V, Kariluoto S. Liu F, et al. Food Funct. 2022 Mar 21;13(6):3220-3233. doi: 10.1039/d1fo03352b. Food Funct. 2022. PMID: 35212339
Folates were identified and quantitated by a UHPLC-PDA/FL method. Folic acid and 10-formylfolic acid were stable throughout the digestion, and the conversions among formyl folates and 5,10-methenyltetrahydrofolate were triggered at the gastric phase. ...The h …

Cofactor role for 10-formyldihydrofolic acid.
Baggott JE, Johanning GL, Branham KE, Prince CW, Morgan SL, Eto I, Vaughn WH. Baggott JE, et al. Biochem J. 1995 Jun 15;308 ( Pt 3)(Pt 3):1031-6. doi: 10.1042/bj3081031. Biochem J. 1995. PMID: 8948466 Free PMC article.
The spectral properties indicated that the 10-HCO-H2folate preparation is not appreciably contaminated with 10-HCO-H4folate, 5,10-methenyltetrahydrofolic acid (5,10-CH = H4folate) or 10-formylfolic acid (10-HCO-folate). The above data establish that the 10-HC …

Aspects of intestinal folate transport in the rat.
Blair JA, Johnson IT, Matty AJ. Blair JA, et al. J Physiol. 1976 Mar;256(1):197-208. doi: 10.1113/jphysiol.1976.sp011320. J Physiol. 1976. PMID: 933030 Free PMC article.
The presence of 2:4 dinitrophenol, and the absence of oxygen, in the muscosal bathing medium both led to a decrease in the tissue accumulation and serosal transfer of folic acid by everted sacs. 3. 10-formylfolic acid, present in the mucosal medium at a molar …

Modelling folates reaction kinetics during cowpea seed germination in comparison with soaking.
Coffigniez F, Rychlik M, Mestres C, Striegel L, Bohuon P, Briffaz A. Coffigniez F, et al. Food Chem. 2021 Mar 15;340:127960. doi: 10.1016/j.foodchem.2020.127960. Epub 2020 Sep 2. Food Chem. 2021. PMID: 32916403
A modelling approach has been developed to characterize the reactivity of folates in cowpea seeds during germination at 30 C, using a water-to-seed ratio of 1:1 (w/w). For this purpose, the concentrations of folic acid, 10-formylfolic acid, 5-methyltetrahydro …

Folate Content and Yolk Color of Hen Eggs from Different Farming Systems.
Czarnowska-Kujawska M, Draszanowska A, Gujska E, Klepacka J, Kasińska M. Czarnowska-Kujawska M, et al. Molecules. 2021 Feb 16;26(4):1034. doi: 10.3390/molecules26041034. Molecules. 2021. PMID: 33669220 Free PMC article.
The predominant folate form found in egg was 5-methyltetrahydrofolate, which showed considerably greater stability under boiling compared to 10-formylfolic acid present in a lower amount. In most eggs tested, the losses in total folate content did not exceed …

Development of stable isotope dilution assays for the quantitation of intra- and extracellular folate patterns of Bifidobacterium adolescentis.
Kopp M, Dürr K, Steigleder M, Clavel T, Rychlik M. Kopp M, et al. J Chromatogr A. 2016 Oct 21;1469:48-59. doi: 10.1016/j.chroma.2016.09.048. Epub 2016 Sep 22. J Chromatogr A. 2016. PMID: 27692648
Therefore, B. adolescentis DSM 20083(T) was cultivated in folate-free medium (FFM) for 24h to develop and validate stable isotope dilution assays (SIDAs) coupled with LC-MS/MS for the determination of 5-formyltetrahydrofolic acid (5-HCO-H(4)folate), 10-formylfolic …

The use of a plant enzyme for rapid and sensitive analysis of naturally-occurring folates in food by liquid chromatography-tandem mass spectrometry.
Ložnjak P, García-Salinas C, Díaz de la Garza RI, Bysted A, Jakobsen J. Ložnjak P, et al. J Chromatogr A. 2019 Jun 7;1594:34-44. doi: 10.1016/j.chroma.2019.02.037. Epub 2019 Feb 16. J Chromatogr A. 2019. PMID: 30799066
Six commonly occurring folate forms (tetrahydrofolate, 5,10-methenyltetrahydrofolate, 10-formylfolic acid, 5-formyltetrahydrofolate, folic acid and 5-methyltetrahydrofolate) were detected and quantified in 9 min using liquid chromatography-tandem mass spectro …
