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.

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

A model of a molecule of arginine, an amino acid. Amino acids are the building blocks of proteins and have many functions in metabolism. In particular, Arginine has an important function in the immune system, wound healing and cell division.

Prednisone is a glucocorticoid medication mostly used to suppress the immune system and decrease inflammation in conditions such as asthma, COPD, and rheumatologic diseases.

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

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.
