asset_class: peptide-analog

c_terminal_modification: amide

synthesis_statement: Class-specific non-operational enablement context: this packet identifies exact canonical L peptide molecules derived from the curated human PACAP-38 sequence basis parent scaffold and configured terminal, salt, and bridge states. It is not a synthesis protocol, formulation recipe, manufacturing instruction, dosing instruction, assay protocol, safety claim, efficacy claim, target-engagement claim, or therapeutic-use claim.

reason: The v1 exact-row contract currently supports canonical L stereochemistry only.

reason: The v1 exact-row contract rejects side-chain modification objects until an exact reviewed schema is implemented.

reason: Only cyclization or bridge states explicitly listed in form_variants are represented.

reason: The v1 exact-row contract rejects conjugates until attachment chemistry is represented exactly.

reason: Generated rows intentionally do not include dosing instructions, formulation recipes, assay protocols, or operational synthesis procedures.

reason: Generated rows do not assert activity, affinity, efficacy, safety, indication, or commercial developability.

attachment_residue: C-terminus

label: C-amide terminal form, hydrochloride salt form

salt_or_counterion: hydrochloride

limitations: No activity, efficacy, safety, or therapeutic-use prediction is made by this identity row.

quality_letter: D

salt_form: hydrochloride

target_context: Human PACAP-38 identity context from UniProtKB P18509 ADCYAP1-derived peptide feature, represented as exact canonical L peptide identities with configured C-terminal amide form variants. This row set asserts exact peptide identities only and does not assert neuroendocrine, CNS, vascular, safety, dosing, formulation, target-engagement, or clinical effects.
