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
Proteasomes are large molecular machines that degrade unneeded or damaged proteins that have been tagged with polyubiquitin.
Immunoglobulin G (IgG) - 3d rendered image. Microbiology illustration  the structure of an antibody. The Y-shaped structure. IgG is the most common type of antibody. Hologram view. SEM.
Procedural growth of matter
Abstract background of curved wires
Gamma secretase protein complex. Multi-subunit intramembrane protease that plays role in processing of proteins. 3D illustration.
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.

Interleukin 13 (IL-13) cytokine protein. 3D illustration. Cartoon representation combined with semi-transparent surfaces.
A ribbons model of an antibody, also known as immunoglobin. The immune system produces antibodies (using white blood cells) which then identify and attack viruses and bacteria.
Passive immunization with nanobodies: three neutralizing nanobodies (blue) bound to the receptor-binding domain of the omikron SARS-CoV-2 spike protein. Nanobodies can have a highly increased neutralizing activity compared to antibodies.
