orange: RNA primer; red: RNA template; light blue: proofreading riboexonuclease; mid blue: helicase; dark blue: RNA directed RNA polymerase; violet: non structural proteins (NSPs).
A ball and stick + ribbons model of human Interleukin 2 or IL-2. Interleukin is a hormone which acts as a signalling molecule for the immune system.
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.
3D cartoon and Gaussian surface models, chain entity color scheme, PDB 4oo8, white background
Immunoglobulin G (IgG) - 3d rendered image. Microbiology illustration  the structure of an antibody. The Y-shaped structure. IgG is the most common type of antibody.
The crystal structure of the tumor marker protein. The 3D model of the biological macromolecule.
Beta-amyloid (Abeta) peptide, 3D rendering. Major component of plaques found in Alzheimer's disease. Cartoon representation.
Freshness capsule
Aztreonam (left, orange) inhibits the beta-lactamase from Acinetobacter species. Avibactam (red) inhibits the beta-lactamase (blue) of Clostridioides difficile.
A ball and stick + ribbons model of beta-secretase - a protein that is important in forming healthy peripheral nerve cells, but is also involved in the onset of Alzheimer's disease.
Recombinant human insulin. 3d cartoon model based on protein data bank
Molecular Model of Human Insulin with disulfide bonds shown.
3D cartoon and Gaussian surface models, PDB 6vg8, white background
Rendered coronavirus/2019-nCoV single-stranded RNA, built from experimentally determined Ebola virus crystal structure. Color symbols - bluewhite=carbon, pink=oxygen, lightblue=nitrogen, white=hydrogen, lavender=phosphorus
Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
Transfer RNA (abbreviated tRNA and formerly referred to as sRNA, for soluble RNA with RNA strand in the cell 3d rendering
Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria.  Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.
A ball-and-stick 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.
3D Render of Popcorn Themed Font  Number 2
Molecular Model of Infliximab, or Remicade, a monoclonal antibody against tumour necrosis factor alpha (TNF-α), which is used to treat autoimmune diseases
3D cartoon and Gaussian surface models, PDB 2zva, white background
Calreticulin, a protein which binds to misfolded proteins and prevents them from being exported from the endoplasmic reticulum to the Golgi apparatus. 3d rendering.
Aromatase (estrogen synthase) enzyme. Protein responsible for the key step in the synthesis of estrogens. 3D illustration. Cartoon representation.
3D model of a protein molecule. Endothelial tyrosine kinase receptor, a marker of angiogenesis.
The amyloid beta peptide is a component of the amyloid precursor protein, which is normally bound to a cell membrane. The gamma secretase enzyme cuts the free form out, that aggregates to amyloid plaques.
A ball and stick + ribbons model of HIV protease - an enzyme that is the target of much AIDS and HIV research.
DNA polymerase I. An enzyme that participates in the DNA replication. Shown with a fragment of the DNA
Molecular Model of Human Insulin with disulfide bonds shown.
3D cartoon model, secondary structure color scheme, PDB 2rfn, white background
Brain-derived neurotrophic factor (3d), also known as BDNF, a protein that supports the survival of existing neurons, and encourages the growth and differentiation of new neurons and synapses.
