Ubiquitin is a small regulatory protein found in most tissues of eukaryotic organisms, i.e., it is found ubiquitously. 3D cartoon and Gaussian surface models, white background.
Bacteria pathogen - 3d rendered microbiology image. Illustrate of Lactobacillus Bulgaricus Bacteria, Microbacterium Tuberculosis Bacteria (MTB). Medical research, health-care concept. SEM (TEM) scanning view
orange: RNA primer; red: RNA template; light blue: proofreading riboexonuclease; mid blue: helicase; dark blue: RNA directed RNA polymerase; violet: non structural proteins (NSPs).
A ball and stick model of a molecule of Human Interferon. Interferons are proteins important in the working of the immune system and are produced in large numbers in the presence of viruses, bacteria, tumors and parasites.  Interferons are used in drugs to combat cancer, multiple sclerosis, hepatitis B and C and other diseases. Isolated on white.

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.
Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
Squalane is a hydrocarbon derived by hydrogenation of squalene. 3d illustration

A molecular model of the flavonoid Quercetin.  An antioxidant and anti-inflamatory, it is used as a nutritional suplement.  It is commonly found in many fruits and vegetables and is a significant chemical component of tea.  Isolated on white.
Cediranib cancer drug molecule. 3D rendering. Atoms are represented as spheres with conventional color coding.
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
Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics  from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet),  ampicillin (red).

Tryptophan or Trp is an alpha-amino acid that is used in the biosynthesis of proteins, 3d illustration
Bone marrow plasma cells .Plasma cell neoplasms are diseases in which the body makes too many plasma cells. Plasma cell neoplasms can be benign or malignant. Diagnosed with Immunostain CD138 positive.
TNF-alfa (blue) is the most potent proinflammatory cytokine and is crucial in the pathogenesis of PsA. TNF-  inhibitors considerably relieve symptons in patients. A therapeutic antibody (adalimumab) blocks the receptor binding site of  TNF-.
