IUPAC Name:
Due to the size and complexity of this 83-amino acid polypeptide, a complete IUPAC name is not commonly used. The peptide is designated by its sequence and modified structure.

Structure Representation:
SMILES:
Not available due to size; identified by primary sequence and structural motif classification.

Peptide Classification:
Synthetic polypeptide analogue of human IGF-1; modified to increase half-life and bioactivity in receptor-binding studies
