Hydrogen-bond donors
hbd_lipinski
Count of N-H and O-H donors (Lipinski Rule-of-5 definition). For cyclic peptides, the dominant single determinant of passive membrane permeability. 100% match vs CycPeptMPDB.
Calculated from chemical structure (RDKit) when a peptide-scale SMILES is available (MW ≤ 10 kDa). Values appear on peptide records under the physicochemical profile.
