Chemical Information
FooDB NameFe2+
DescriptionFe2+, also known as fe (ii) ion or fe(ii), is a member of the class of compounds known as homogeneous transition metal compounds. Homogeneous transition metal compounds are inorganic compounds containing only metal atoms,with the largest atom being a transition metal atom. Fe2+ can be found in a number of food items such as soft-necked garlic, yardlong bean, common verbena, and purslane, which makes fe2+ a potential biomarker for the consumption of these food products. Fe2+ can be found primarily in blood, cerebrospinal fluid (CSF), saliva, and urine, as well as in human brain and liver tissues. Fe2+ exists in all living species, ranging from bacteria to humans. In humans, fe2+ is involved in several metabolic pathways, some of which include carnitine synthesis, cystinosis, ocular nonnephropathic, porphyrin metabolism, and catecholamine biosynthesis. Fe2+ is also involved in several metabolic disorders, some of which include tyrosinemia type 2 (or richner-hanhart syndrome), tyrosinemia type 3 (TYRO3), dihydropyrimidinase deficiency, and tyrosine hydroxylase deficiency. Moreover, fe2+ is found to be associated with alzheimer's disease, multiple sclerosis, and parkinson's disease.
