A ball-and-stick plus ribbons molecular model of the hormone Orexin, also known as Hypocretin. Orexin is involved in the regulation of the sleep/wake cycle and it stimulates apetite, wakefulness and energy expenditure. It has been linked with Alzheimer's disease. Isolated on white.

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.

C-reactive protein (CRP), an annular (ring-shaped), protein found in blood plasma. It is thought to assist in complement binding to foreign and damaged cells and enhances phagocytosis by macrophages.
