Possible Interaction: Citric Acid and Iron, Dietary

“Since chelating agents like citric acid can compete with the storage proteins for iron , we suggest that the Fe(III)-citrate complexes studied here may be formed in vivo and participate in regulating biologic calcification.”

“ CA inhibited the growth of Fe(II)OB, decreased the formation of metal plaque and increased Fe and Mn accumulation in reeds.”

“ Iron can react with citric acid , interfering with the Krebs cycle, hence with oxidative phosphorylation.”

“Significant correlations were found between citric acid contents and dialysability of Zn and Fe.”

“The addition of organic acids including tartaric acid (TA), citric acid CA ), and ascorbic acid (AA) can form complex with iron in pyrite, which promotes the Fe(II) dissolution.”

“The addition of CA successfully prevented the precipitation of iron and facilitated TCE degradation.”

“Applying citric acid (20 mmol kg-1) to soil increased in 14-, 10-, 7-, 2- and 1.4- fold the concentration of Mn, Fe , Co, Ni, and Cr, respectively, compared to the control.”

“Both ferric and ferrous iron had substantial effects on the DBP formation of surrogates ( citric acid and catechol in particular), which implied that the catalytic effects of ferric and ferrous iron mainly depended on molecular weight.”

“ CA significantly (p<0.01) inhibited the growth of Fe(II)OB and decreased the formation of Fe plaque.”

“However, … mM citric acid significantly promoted Cu mobilization (from 1 mg kg(-1) in the control to 42 mg kg(-1) … 10 mM citric acid) and reduced the exchangeable (from 21 to 3 mg kg(-1)) and the Fe and Mn oxides (from 443 … 277 mg kg(-1)) fractions.”
