Residue view
Soft tints mark standard side-chain classes for scanning. Primary emphasis is reserved for reported modifications, termini, secondary-structure tracks, and topology links.
Features are shown only when a reported notation or topology record supports them.
Structure & chemistry

Not availableChemical graph string used for atom-level 2D depiction when available.
Not availableA 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.

Covalent topology & modificationsnone
No reviewed form-level topology or residue-level connection annotation is attached to this peptide in the current release. This is not evidence that every molecular form is linear or unmodified.

Charge & residue composition
Modeled net charge across common formulation and assay pH checkpoints.
Grouped composition is often more interpretable than a long amino-acid list.
Hydropathy & amphipathic windows
Seven-residue sliding windows expose local patches hidden by whole-sequence GRAVY.
Top alpha-helix hydrophobic-moment windows across 12, 15, 18, and 21 residues.
Sequence-liability cues
Motifs are review prompts for formulation or CMC interpretation; they are not degradation predictions.
Alpha-helix amphipathic projection
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.
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.
Computed from the standard parent-residue sequence; protein-origin metrics defined at any length.
Above 40 — predicted unstable in vitro.
A280 (1 g/L) ≈ 0.00 · 125 M⁻¹·cm⁻¹ with 1 disulfide
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.
