In the specialized field of peptide research, understanding the molecular architecture of synthetic compounds is essential for analyzing their potential applications. Among various research-grade compounds, the CN-105 structure or sequence peptide has garnered significant attention due to its unique design as a mimetic of the endogenous apolipoprotein E (apoE). As a researcher interested in peptide synthesis and structural biology, I have found that examining the specific arrangement of amino acids provides vital insights into how these molecules int Jan 6, 2026 — To predict an AA sequence structure: Open the AA sequence for which you want to predict the structure; Navigate to the 3D Structure tab of eract with biological pathways.
Defining the CN-105 Sequence
The CN-105 compound is a specialized apoE mimetic peptide designed to replicate the polar face of the apoE helical domain. Structurally, it is a 5 amino acid peptide characterized by the sequence: acetyl-Valine-Serine-Arginine-Arginine-Arginine-amide.
This specific sequence is a classic example of how terminal modifications—such as N-terminal acetylation and C-terminal amidation—are employed to stabilize the structure and minimize the net charge, allowing the molecule to effectively imitate natural protein motifs. When comparing this to a standard tetrapeptide structure, the addition of the fifth residue is critical to the functional profile of the peptide.

* Comparison to Other Peptides: While other research materials like C105Y (a cell-penetrating peptide derived from alpha1-antitrypsin) or the radiolabeled AE105 peptide (Asp-Cha-Phe-(d)Ser-(d)Arg-Tyr-Leu-Trp-Ser-CONH2) serve different functional roles, they underscore the importance of the sequence structure in determining biological affinity.
Why Sequence Structure Matters
The study of sequences and their corresponding structures is a cornerstone of modern biochemistry. Whether one is looking at the Calcitonin gene-related peptide (CGRP), which by VH Engelhard · 1994 · Cited by 594 — This review summarizes this information and describes how it accounts for both the specificity and degeneracy of peptide binding. is a 37-amino acid neuropeptide, or the shorter CN-105, the spatial orientation of the amino acids is what defines the molecule's efficacy.
When mapping out a sequence structure, researchers often look for repeating patterns of polar and non-polar residues. This pattern often dictates whether a molecule will form a stable beta-sheet or maintain an alpha-helical conformation. In the case of CN-105, the focus was on creating a peptide that could effectively cross biological barriers and modulate neuroinflammatory pathways, a testament to how precise 105-based design strategies can be.
