Phospholipid bilayer membrane structures that make up living cells and their contents. This is an image of membrane proteins in the membrane.\nThis image, which looks like a plastic model, evokes biology and biochemistry. It can be used as a cover for magazines, textbooks and presentation materials.\nThis image was not created by AI.
A ball and stick model of a Polytetrafluoroethylene molecule, also known as PTFE or most commonly Teflon. It is a polymer consisting of only carbon and fluorine atoms. It is used as a non-stick coating for cookware, as a lubricant, and it is also used to contain highly reactive chemicals as it is extremely non-reactive.
Biological protein and molecule, 3d rendering. 3D illustration.
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.

Mefloquine is a medication used to prevent or treat malaria.When used for prevention it is taken once a week and should be started one or two weeks before potential exposure. 3d illustration
Four different stages of a trees lifecycle are presented in a progressive sequence from left to right. Each stage, from a seedling to a mature tree, is placed atop a cylindrical pedestal with colors transitioning from red to blue, symbolizing growth and development.
Biological protein and molecule, 3d rendering. 3D illustration.
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.

Epidermis. Electron microscope micrograph showing a keratinocyte of spinous layer. The epithelial cell has a polygonal shape, central nucleus with nucleolus, cytoplasm full of keratin filament bundles, and numerous dark desmosomes crossing the intercellular spaces.
View of Ha Long Bay, Quang Ninh province, Vietnam; with a lot of limestone islets and cruise ships; on a blue sky summer day. Travel and landscape concept.
Proteasomes are a large molecular machine that degrade unneeded or damaged proteins that have been tagged with polyubiquitin (yellow). The ubiquitin hydrolase (violet) detaches ubiquitin from the protein, that is unfolded and degraded into small peptides (bottom). Source: PDB entry 5GJQ
Structural model of Benzene molecule
CD47 also known as integrin associated protein is a transmembrane protein that in humans is encoded by the CD47 gene. CD47 belongs to the immunoglobulin superfamily and partners with membrane integrins and also binds the ligands thrombospondin-1 and signal-regulatory protein alpha. 3D cartoon and Gaussian surface models, chain id color scheme, based on PDB 2jjt, white background
A breathtaking image of Ao Phang Nga National Park, capturing the dramatic limestone cliffs and emerald-green waters. This iconic landscape, dotted with lush islands and tranquil coves, epitomizes the serene beauty and geological wonder of this renowned area in Thailand.
