I'm writing an article and it is focused on a neuropeptide, ghrelin. I would like to hear your comments about how this statement makes you feel grammatically:
"...including ghrelin, motilin, gastric inhibitory polypeptide, and cholecystokinin. Of interest, ghrelin has been..."
I do not want to give a broad info about the molecules other than ghrelin. However, I have to say that ghrelin is one among others and then continue to tell about ghrelin. I'm not sure if using "of interest" in this way is appropriate.

I wouldn't write it like that. I would just start the second sentence with 'In particular, ghrelin has been' or 'ghrelin is one of the most....' or 'of these, ghrelin ...' something like that.

I changed it as 'of ghrelin'. Thanks a lot.
