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.
3d helix chromosome or Dna structure, technology science background. 3d render illustration
Chain of Amino Acid. Proteins consist of one or more chains of amino acids called polypeptides
3D cartoon and Gaussian surface models, chain id color scheme, PDB 7t3a, white background
A ball-and-stick plus ribbons molecular model of the hormone Orexin, also known as Hypocretin.  Orexin is involved in the regulation of the sleep/wake cycle and it stimulates apetite, wakefulness and energy expenditure. It has been linked with Alzheimer's disease.  Isolated on white.
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.
Chain of amino acid or bio molecules called protein - 3d illustration
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.

From left to right: the NMDA and  AMPA receptors transport calcium cations into neurons after being activated by the neurotransmitter glutamate and  the GABA receptor (right) transport chloride anions after the activation by gamma aminobutyrate. PDB entries: 6wht,  3kg2, 6d6u
Focal nodular hyperplasia (FNH) is a benign liver lesion that is composed of a proliferation of hyperplastic hepatocytes surrounding a central stellate scar. Typically, FNH is a solitary lesion that is more commonly seen in women.
Science background with molecule or atom
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.

Dna structure on science background. 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.
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.
