About Melanocortin & Reproductive Peptides

Melanocortin and reproductive-axis sequences frequently contain cyclic structures, which affects both mass interpretation and chromatographic behaviour.

What this category covers

This category covers melanocortin-receptor and reproductive-axis sequences studied in signalling research models. Several compounds in this class are cyclic rather than linear.

How these are tested

Cyclic peptides show a mass shift relative to their linear counterparts due to loss of water on ring closure. Certificates should report a mass consistent with the cyclic form. Our lots confirm identity by mass and purity by HPLC.

How to compare within this class

Verify that the reported molecular weight corresponds to the cyclic rather than linear form, and that the certificate identifies the topology explicitly where relevant.
