Computed descriptor·Structure-derived
Topological polar surface area
tpsa · Ų
Sum of polar (N,O) surface contributions. Strong correlate of passive permeability and oral absorption. Exact match vs CycPeptMPDB precomputed.
Calculated from chemical structure (RDKit) when a peptide-scale SMILES is available (MW ≤ 10 kDa). Values appear on peptide records under the physicochemical profile.
