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.
Spike glycoprotein homotrimer, a main target for neutralization antibody, to bind its receptor, ACE2, and mediate membrane fusion and virus entry. 3D cartoon and Gaussian surface models, white background.

The LDL-receptor (red) is a membrane protein found in almost every human cell. It binds to the apoprotein B100 from LDL-particles and mediates their internalization (endocytosis) in the cell. This occurs in almost all cells but mainly in the liver where it removes about 70 % of LDL from the circulation.

mRNA (multicoloured strand) is decoded in a ribosome to produce an aminoacid chain, that folds into a protein (red). tRNA (dark violet) molecules carry single aminoacids that are incoporated into the growing chain.

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
A model of a nucleosome. Isolated on black.
Biological protein and molecule, 3d rendering. 3D illustration.
A conceptual image of an abstract network of multi-coloured organic strands arranged in a non regular pattern all connected together in a complex manner. The network is made from smaller multi-coloured squares and polyhedra, in vivid colours against a pastel toned background. Shows background and foreground elements to the structure.

Chloride channels conduct chloride anions across cell membranes, regulating the electrical excitation of skeletal muscles and the flow of salt and water across epithelial barriers. They also play an importante role in  regulation of pH, volume homeostasis, organic solute transport, cell migration, cell proliferation and differentiation.Genetic defects in Cl- channels underlie several familial muscle and kidney diseases.
