Chemical Property Profile of beta-Lactose
Property Insights of beta-Lactose
The XLogP value of -4.7 indicates that beta-Lactose is hydrophilic (water-soluble), making it suitable for aqueous formulations and biological assay applications. The TPSA of 190.0 Ų indicates high polarity, suggesting beta-Lactose may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, beta-Lactose has 8 hydrogen bond donor(s) and 11 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
