Soft tints mark standard side-chain classes for scanning. Primary emphasis is reserved for reported modifications, termini, secondary-structure tracks, and topology links.

Peptidoform features

Features are shown only when a reported notation or topology record supports them.

No terminal modification, residue-level marker, disulfide, staple, coordination, or other topology signal is currently available.

A reviewed SMILES is required before a 2D molecular depiction can be shown. Sequence and HELM remain useful for identity interpretation, but they do not replace a chemical graph.

Motifs are review prompts for formulation or CMC interpretation; they are not degradation predictions.

Asn deamidation motif

Asn followed by small/polar residues is a known sequence context to review for deamidation susceptibility.

Asp-containing motifs can merit review for isomerization or related degradation pathways.
Oxidation-sensitive residues

The pale sector marks the direction of the hydrophobic face inferred from μH. This is a projection assumption, not a measured fold.
HydrophobicAromaticPolarBasic +Acidic −Specialhydrophobic faceμH arrow → hydrophobic face

The projection assumes an α-helix conformation; a long μH arrow indicates an amphipathic helix, common in antimicrobial peptides.Sequence > 30 aa — only termini and every fifth position are numbered because later turns share earlier wheel angles.

Method notes

Charge model: side-chain pKa D 3.9, E 4.1, C 8.5, Y 10.1, H 6.5, K 10.8, R 12.5 with EMBOSS termini. pI is estimated by binary search on modeled net charge. Hydropathy uses Kyte-Doolittle values; hydrophobic moment follows the Eisenberg alpha-helix vector-sum convention. When the basis is a parent-residue sequence, modified chemistry is intentionally not inferred.

Computed developability descriptors

Deterministic descriptors computed from the reviewed sequence or chemical structure (RDKit), each anchored to a literature method. These are computed estimates for developability interpretation — not experimental measurements — and are validated against independent reference implementations.

Sequence-derived

Computed from the standard parent-residue sequence; protein-origin metrics defined at any length.

Structure-derived descriptors are not shown because this identity has no resolved chemical structure (SMILES). This is a known coverage gap for disulfide-rich and unresolved peptidoforms, not a computation error.

ADMETatlas
peptide evidence atlas

ADMETatlas is an open, curated atlas of ADMET evidence for therapeutic peptides — spanning developability, membrane permeability and blood–brain-barrier transport, immune-recognition context, and approved-product context. Every measurement stays linked to its original source, with stable identifiers and transparent curation, so results can be traced, cited, and reproduced.
