Property Insights of Vitamin D1

The XLogP value of 14.9718 indicates that Vitamin D1 is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 40.46 Ų, Vitamin D1 exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Vitamin D1 has 2 hydrogen bond donor(s) and 2 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
