Property Insights of cobalamin

The XLogP value of 4.84874 indicates that cobalamin is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 467.31 Ų indicates high polarity, suggesting cobalamin may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, cobalamin has 10 hydrogen bond donor(s) and 14 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
