Side-chain classNonpolarPolarBasic (+)Acidic (−)Modified

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.

Representation class

How the current release can interpret this identity chemically.

Not available

SMILES

Chemical graph string used for atom-level 2D depiction when available.

Not available

No atom-level graph

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.

3D structure referencesnone attached

3D structure not available

A 3D structure isn't available for this peptide in the current release. Chemistry and topology fields remain available when represented by sequence, HELM, or SMILES.

Covalent topology & modificationsnone

Exact topology not established

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.

Physicochemical profile

Computed sequence-derived descriptors and any measured physicochemical evidence such as lipophilicity. Computed values are interpretation aids, not experimental ADMET measurements.

Sequence-liability cues

Sequence-liability notes

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

Oxidation-sensitive residues

M · pos 4

Met, Trp, and Cys residues can merit formulation review for oxidation or covalent-state sensitivity.

Projection angle100° / residue

The pale sector marks the direction of the hydrophobic face inferred from μ_H. This is a projection assumption, not a measured fold.

HydrophobicAromaticPolarBasic +Acidic −Specialhydrophobic faceμ_H arrow → hydrophobic face

The projection assumes an α-helix conformation; a long μ_H arrow indicates an amphipathic helix, common in antimicrobial peptides.

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.

Aliphatic index

16.11

Instability index

28.2

At or below 40 — predicted stable in vitro.

Boman index

3.58 kcal/mol

Above 2.48 — elevated potential protein-binding.

Molar extinction coefficient (280 nm)

2,980 M⁻¹·cm⁻¹

A280 (1 g/L) ≈ 1.36

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.
