Cardiogen vs Cartalax: what’s the difference?

Short answer: Cardiogen is Ala-Glu-Asp-Arg (AEDR; PubChem CID 11583989). Cartalax is Ala-Glu-Asp (AED; CID 87815447). They share an N-terminal AED motif; Cardiogen adds C-terminal Arg. To buy Cartalax or compare related bioregulators, use the product pages linked below.

Sequence and identifier spec sheet

Direct answer: Match each bioregulator by sequence and CID first, then by trade name. The table below is the identity layer this post uses for both comparison pairs.

Name Sequence CID Formula MW (g/mol) CAS / notes
Cartalax Ala-Glu-Asp (AED) 87815447 C12H19N3O8 333.29 85806-95-7
Cardiogen Ala-Glu-Asp-Arg (AEDR) 11583989 C18H31N7O9 489.5 857267-11-9
Chonluten Glu-Asp-Gly (EDG) 194641 C11H17N3O8 319.27 —
Bronchogen Ala-Glu-Asp-Leu (AEDL) 11690869 C18H30N4O9 446.5 857267-12-0

What this tells us: Cartalax and Cardiogen are length variants of the same AED motif. Chonluten and Bronchogen are unrelated sequences to each other — EDG vs AEDL — so the second pair is a naming comparison, not a one-residue extension.

Cardiogen vs Cartalax in detail

Direct answer: Cartalax stops at Asp; Cardiogen continues with Arg. That single residue changes molecular weight (333.29 vs 489.5), formula and CID. Product pages: Cartalax and Cardiogen . Companion explainers already published for Cardiogen can be linked once slug is confirmed.

Chonluten vs Bronchogen

Direct answer: Chonluten is Glu-Asp-Gly (EDG); Bronchogen is Ala-Glu-Asp-Leu (AEDL). They do not share a continuous residue extension relationship the way Cartalax/Cardiogen do. See What Is Bronchogen? for the AEDL reference post.

Are these bioregulator peptides?

Direct answer: Yes — they are commonly grouped among Khavinson-type short peptide bioregulators. Class labels do not replace sequence identity. Docking or histone-binding numbers from published Khavinson-group papers should be quoted only with the original PMID/PMC and without organ-benefit language.

Frequently asked questions

What is the difference between Cardiogen and Cartalax?

Cardiogen is the tetrapeptide Ala-Glu-Asp-Arg (AEDR; PubChem CID 11583989). Cartalax is the tripeptide Ala-Glu-Asp (AED; PubChem CID 87815447). They share an N-terminal Ala-Glu-Asp motif; Cardiogen adds a C-terminal Arg.

How do Chonluten and Bronchogen differ?

Chonluten is the tripeptide Glu-Asp-Gly (EDG; PubChem CID 194641). Bronchogen is the tetrapeptide Ala-Glu-Asp-Leu (AEDL; PubChem CID 11690869). They are different sequences and lengths; do not treat the names as interchangeable.

Are these bioregulator peptides?

Yes. These short synthetic peptides are commonly grouped among Khavinson-type peptide bioregulators. Each entry should still be matched by sequence and PubChem CID, not by the class label alone.

Where are the product pages for these peptides?

Modern Aminos lists public product pages for Cartalax, Cardiogen, Chonluten and Bronchogen. This comparison post links those pages for laboratory documentation; all applicable tests are performed on our products.

How is purity checked?

All applicable tests are performed on our products. Current certificates are listed in each product Certificate of Analysis tab and via COA Search.
