General description

Obestatin is a 23-amino acid peptide. It is encoded by the ghrelin gene.

Application

Human obestatin has been used to study its role in differentiation in rat preadipocytes.

Biochem/physiol Actions

It does not participate in the release of growth hormone.
Obestatin, an obesity peptide, along with Ghrelin peptides are derived from the same prepropeptide, Ghrelin. In contrast to Ghrelin, Obestatin suppresses food intake, body weight gain, and gastrointestinal motility in rodents.

Physical form

Lyophilized from 0.1% aqueous trifluoroacetate (TFA).

Other Notes

Lyophilized from 0.1% TFA in H2O
