C18 partitioning, followed by Nab, its linear isomer, and then Nle, with an additional methylene unit (Figure ). Similarly, the methanol solubility, with a fixed volume of ACN, followed a decreasing trend as Nl > Nab > Nle (Table ). Calculated LogP corroborate these observations, with hydrophobicity increasing as Nl > Nab > Nle (Table ).
