Bilayer Lipid Membrane - 3d rendered image of Cell Membrane Phospholipid Structure, Phospholipid bilayer of the cell membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.

Cell Membrane and Molecules, 3d rendering. Computer digital drawing.

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.

$The three-dimensional structure of proteins is represented in a variety of conformations. This image is based on the ribbon structure of a protein. It is suitable for biology notebooks and book covers.\nThis image has not been created by AI.$

Chain of amino acid or bio molecules called protein - 3d illustration

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

orange: RNA primer; red: RNA template; light blue: proofreading riboexonuclease; mid blue: helicase; dark blue: RNA directed RNA polymerase; violet: non structural proteins (NSPs).

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.

An antibody, also known as an immunoglobulin, is a large, Y-shaped protein used by the immune system to identify and neutralize foreign objects such as pathogenic bacteria and viruses. 3D cartoon and Gaussian surface models with differently colored chains, white background.

ATP Synthase Protein - 3d rendered image. Medical microbiology concept. Structure and conformational states of the bovine mitochondrial ATP (Adenosine triphosphate) synthase. Chemical energy is synthesized in eukaryotic cells primarily. Hydrolase. Hologram view. HUD, FUI

DNA close-up, DNA Molecule Model, DNA Strands, DNA animation

$Phospholipid bilayer membrane structures that make up living cells and their contents. This is an image of membrane proteins in the membrane.\nThis image, which looks like a plastic model, evokes biology and biochemistry. It can be used as a cover for magazines, textbooks and presentation materials.\nThis image was not created by AI.$

C-reactive protein (CRP), an annular (ring-shaped), protein found in blood plasma. It is thought to assist in complement binding to foreign and damaged cells and enhances phagocytosis by macrophages.

Covid-19 Coronavirus Variants Omicron Delta Gamma Beta Alpha Pandemic Virus Disease Mutation

Immunotherapy of Alzheimer's disease: Monoclonal antibody (light blue) bound to an amyloid beta peptide (orange), that is aggregated to amyloid beta fibrils, which build up amyloid plaques.

Digital background depicting innovative technologies in (AI) artificial systems, neural interfaces and internet machine learning technologies

3D cartoon and Gaussian surface models, PDB 2gjx, white background

A ribbons model of an antibody, also known as immunoglobin. The immune system produces antibodies (using white blood cells) which then identify and attack viruses and bacteria.

Cell membrane structure background, 3d rendering. Digital drawing.

Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway. Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.

Rhodopsin (the extremely sensitive to light pigment involved in vision process) protein structure

The NEK-7 independent NLRP3 inflammasome in it's hexameric conformation with ADP (red) bound. Inflammasomes are a promising target for the treatment of autoimmune diseases. PDB entry: 7zgu.

Cell membrane cholesterol is shown in pink. 3D cartoon and Gaussian surface models, PDB 7rpk, white background.
