A ball and stick + ribbons model of beta-secretase - a protein that is important in forming healthy peripheral nerve cells, but is also involved in the onset of Alzheimer's disease.
The three-dimensional structure of proteins is represented in a variety of conformations. This image is based on the ribbon structure of a protein. It is suitable for biology notebooks and book covers.\nThis image has not been created by AI.

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.

Myxoid liposarcoma.  Myxoid/round cell liposarcoma, or MRCLS, is one of several types of liposarcoma. Liposarcoma is a rare cancer that grows in the cells that store fat in the body. MRCLS usually grows in the arms and legs. These tumors grow slowly, and they can spread to other parts of the body

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.

Bacteria pathogen - 3d rendered microbiology image. Illustrate of Lactobacillus Bulgaricus Bacteria, Microbacterium Tuberculosis Bacteria (MTB). Medical research, health-care concept. SEM (TEM) scanning view
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.
