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.
Close-up shot of a petri dish for checking an antibiotic in the laboratory.
Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics  from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet),  ampicillin (red).
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.
Squalane is a hydrocarbon derived by hydrogenation of squalene. 3d illustration
Artificial molecular structure in many colors. Horizontal composition, isolated on white background.
Sample of biotite Schist, from the shear zone in the Beitbridge Complex in South Africa. Schist is metamorphic rock caused by pressure during medium grade metamorphism.
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.

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-.
Molecular model of amylose, one of the two sugar components in starch.
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
Tryptophan or Trp is an alpha-amino acid that is used in the biosynthesis of proteins, 3d illustration

A ball and stick model of Elaidic Acid. It is a trans fatty acid and is a very common trans fat found in hydrogenated vegetable oils. Steps are being taken in some countries, including the USA, to ban trans fats in foods due to the increased risk of coronary heart disease in people who eat trans fats.
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.
