The glucagon like peptide-1 receptor (GLPr) is a G proteincoupled receptor (GPCR) that mediates the action of GLP-1, a peptide hormone. The activated receptor  has a strong effect  on the management of type 2 diabetes mellitus and obesity, including glucose homeostasis and regulation of gastric motility and food intake.

A ball and stick model of Eicosapentaenoic Acid or EPA. It is an omega-3 polyunsaturated fatty acid. It is introduced into the diet by eating oily fish. When it comes to fat, there’s one type you don’t want to cut back on: omega-3 fatty acids. Two crucial ones - EPA and DHA - are primarily found in certain fish.
