Inside protein molecule
3D rendering of biotinylated antibody, an engineered protein designed to bind to specific molecules. Biotin allows researchers to easily track and manipulate these antibodies.
DNA mutation, a mutation is a change in a DNA sequence, mutations can result from DNA copying mistakes made during cell division.
This computer-generated image vividly illustrates the invasive Group A Streptococcal bacteria, as they would appear under a microscope. This visual representation helps to understand the microscopic world of Group A Streptococcus and its potential to cause serious diseases.
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.
A ball and stick model of a strand of a molecule of polyvinyl chloride, more commonly known as PVC. This vinyl polymer is one of the commonest plastics in use.

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.
