Calcium folinate | C20H21CaN7O7 - PubChem
Calcium folinate is a tetrahydrofolic acid. Leucovorin Calcium is an active metabolite of folic acid (also called folinic acid and citrovorum factor ), which does not require metabolism by dihydrofolate reductase, the molecular target of folate antagonist-type chemotherapeutic drugs. Leucovorin calcium counteracts the toxic effects of these

The Atomic-Level Structure of Cementitious Calcium
2020/06/11· Despite use of blended cements containing significant amounts of aluminum for over 30 years, the structural nature of aluminum in the main hydration product, calcium aluminate silie hydrate (C-A-S-H), remains elusive. Using first-principles calculations, we predict that aluminum is incorporated into the bridging sites of the linear silie chains and that at high Ca:Si and H2O ratios, …
