Explore sequence length, molecular features, and selected structural modifications.
Each subject below carries an explicit evidence state rather than one forced universal chemistry card. Sequence, molecular formula, molecular weight, and structure availability are shown only when a standardized source was frozen for that exact value — a mixture, form-dependent, or held state is a deliberate scientific outcome, not a missing field.
This explorer summarizes governed structural/chemistry identity data for education only. It is not a pharmacopeial reference, and it does not provide dosing, preparation, or handling guidance.
Structure records
Modified peptide / analogue
IGF-1 LR3 (Long R3 IGF-I)
Sequence-defined peptide
An authoritative PubChem compound CID was not frozen for this subject; a deposited vendor substance record (SID 476298412) is insufficient as sole exact chemistry authority.

Limitations
•An authoritative PubChem compound CID was not frozen for this subject; a deposited vendor substance record (SID 476298412) is insufficient as sole exact chemistry authority.
•The wild-type IGF-I experimental structure must not be substituted for this modified Long R3 IGF-I analogue.
