Neohalicholactone is unusual fatty acid metabolites having a cyclopropane ring and a nine-membered lactone. 3d illustration
Chemical formula of Progesterone
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 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.
Nourish hair of shampoo or serum. Repair damaged hair concept, 3d rendering.
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.
Different fresh products and paper with Tyrosine chemical formula on white wooden table, flat lay. Sources of essential amino acids
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.
Tryptophan or Trp is an alpha-amino acid that is used in the biosynthesis of proteins, 3d illustration

HER2 (light blue)  locked in the inactive conformation by Trastuzumab (left) and Pertuzumab. Trastuzumab has drastically improved the prognosis of HER2-positive breast cancer patients.
A molecular model of Bisphenol A or BPA.  It is a common building block in the production of many epoxy resins and plastics including polycarbonate plastic. As such it is present in a huge range of food packaging and household products. There are now concerns about its health effects, particularly its effect on children, infants and fetuses.   Isolated on white.
