Note
5C-aglycone is one of the two major aglycone urinary water-soluble metabolites of Phylloquinone (Vitamin K1) and menaquinones (vitamin K2), usually excreted as glucuronide conjugates; their structure suggests that they are formed by an oxidative degradation of the phytyl side chain involving enzymes of omega- and beta-oxidation. Newborn infants as a group, are known to have precariously low vitamin K stores and are routinely given vitamin K prophylaxis at birth. (PMIDs 7306367, 4833371, 15722567).
