A ribbons model of Human Growth Hormone, also known as Somatotropin, with a translucent surface model.
Proteasomes are molecular machines for breaking down proteins called proteolysis, only target proteins that have been marked for destruction called ubiquitin to the target protein, 3d rendering
Scientist in clean room laboratory
Proteasomes are large molecular machines that degrade unneeded or damaged proteins that have been tagged with polyubiquitin.

Interleukin 13 (IL-13) cytokine protein. 3D illustration. Cartoon representation combined with semi-transparent surfaces.
Abstract geometric shape
3D model of a protein in coloured shades. The surface irregularities are a realistic representation. Proteins play a very important role in human health. Their research is directly related to medicine and drug discovery, and the image symbolises this.\nBeautiful protein structures can be used as journal covers and inserts.\nIt is a work created by CG. Not created by AI.
