Hello guys. I'm doing a classification for the university and I need to match most of the common peptides to a couple pre-defined categories. I would really appreciate your help on this one:
The peptides are (the usual suspects):
AICAr (I'm not sure if this one counts)
ModGRF(1-29)
GHRP-2
GHRP-6
Fragment 176-191
Hexarelin
Ipamorelin
IGF-1 DES
IGF-1 LR3
MGF
Peg-MGF
Melanotan II
PT-141
Thymosin Beta 4
Triptorelin
The Categories are:
A. Somatotropin, Somatotropin derivatives, Structural analogs
B. Insulin and Insulin salts
C. Other polypeptide hormones, Protein hormones, Glycoprotein hormones and their derivatives
Please don't be tempted to instantly put GHRHs and GHRPs into the category of Somatotropin derivatives because of their GH secretagogue properties since as far as I know GHRPs and GHRHs are neither Somatotropin derivatives, nor structural analogs. Fragment 176-191 fits right into the first category while GHRHs might be a better match for the third. I'm not quite sure but I would definitely be thankful to any expert opinion on this one.
