Particles, medical concept
B-chain pentamer and A-chain subunit (green), 3D cartoon and Gaussian surface model, white background
A ball-and-stick 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.
Nourish hair of shampoo or serum. Repair damaged hair concept, 3d rendering.
Cells in the body examined by endoscope
After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.
