2,4-Dihydroxy-2H-1,4-benzoxazin-3(4H)-one
2,4-Dihydroxy-2H-1,4-benzoxazin-3(4H)-one is a benzoxazinoid precursor of 2-aminophenol sulfate. It is a metabolite found in urine of individuals that have consumed whole grains. It is a particularly strong biomarker for whole grain rye bread consumption (PMID: 23307617). Isolated from seedlings of rye and sweet corn (Zea mays). 2,4-Dihydroxy-2H-1,4-benzoxazin-3(4H)-one is found in cereals and cereal products and fats and oils.
2-Methyl-3-hydroxy-5-formylpyridine-4-carboxylate
2-Methyl-3-hydroxy-5-formylpyridine-4-carboxylate is an intermediate in vitamin B6 metabolism(KEGG ID C06050). It is the 4th to last step in the synthesis of succinate semialdehyde, which is an intermediate in butanoate metabolism. 2-Methyl-3-hydroxy-5-formylpyridine-4-carboxylate is converted from 4-pyridoxate and is then converted to 3-hydroxy-2-methylpyridine-4,5-dicarboxylate. [HMDB] 2-Methyl-3-hydroxy-5-formylpyridine-4-carboxylate is an intermediate in vitamin B6 metabolism(KEGG ID C06050).
