Molecular Structure. Science background. 3D Render

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.

Melatonin is a hormone, released primarily by the pineal gland, that regulates the sleep–wake cycle. 3D ball-and-stick model, white background

A molecular model of Bisphenol A or BPA. It is a common building block in the production of many epoxy resins and plastics including polycarbonate plastic. As such it is present in a huge range of food packaging and household products. There are now concerns about its health effects, particularly its effect on children, infants and fetuses. Isolated on white.

Folic acid, folate molecule. It is known as vitamin B9. Molecular model. 3D rendering. Illustration

Squalane is a hydrocarbon derived by hydrogenation of squalene. 3d illustration

Photomicrograph of rotifer, probably Rotaria rotatoria. Rapidly rotating cilia at top of head, internal organs visible. Green circles are algae. Live specimen. Original image at 40X, wet mount, transmitted brightfield illumination. Indistinct image due to motion blur of live specimen and very shallow depth of field of brightfield illumination.

A molecular model of the flavonoid Quercetin. An antioxidant and anti-inflamatory, it is used as a nutritional suplement. It is commonly found in many fruits and vegetables and is a significant chemical component of tea. 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.

Molecular model of amylose, one of the two sugar components in starch.

Copper(II) sulfate with molecular structure. Chemical ingredient used in medical and public health issues.
