A ribbons model of Human Growth Hormone, also known as Somatotropin, with a translucent surface model.
3D cartoon and Gaussian surface models, PDB 6vg8, white background
Cytochrome P450 molecule. CYP 3A4 is the most promiscuous of the human CYP enzymes. Molecular model. 3D rendering. Illustration
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.
The crystal structure of the tumor marker protein. The 3D model of the biological macromolecule.
DNA A-T Pair
Aromatase (estrogen synthase) enzyme. Protein responsible for the key step in the synthesis of estrogens. 3D illustration. Cartoon representation.
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
PETase (left) degrades  polyethylene terephtalate (PET) into monohydroxyethyl terephthalate (MHET) and MHETase degrades MHET ethylene glycol (EG) and terephthalic acid (TPA). The substrates in the binding sites are depicted in red.
A ball and stick model of Human Insulin. Isolated on black.
3D cartoon and Gaussian surface models. PDB 2aai, white background.
Recombinant human insulin. 3d cartoon model based on protein data bank
3d rendered Gastric inhibitory polypeptide (GIP, glucose-dependent insulinotropic peptide) endocrine protein hormone, 3D illustration
Molecular Model of Infliximab, or Remicade, a monoclonal antibody against tumour necrosis factor alpha (TNF-α), which is used to treat autoimmune diseases
Bovine beta-lactoglobulin protein, 3D structure. Major whey protein, present in cow milk. Important food allergen.
Glutamic acid is an alpha-amino acid that is used by almost all living beings in the biosynthesis of proteins. 3d illustration
The ribonucleotide analogue remdesivir (red) inhibits  the coronavirus replication by blocking the RNA synthesis in the viral RNA dependent RNA polymerase (RdRp, blue).  Four  remdesivir molecules have already been attached to the growing RNA chain. Another remdesivir molecule is entering the active site of the RdRp. Source: PDB entry 7l1f.
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.
3D cartoon and Gaussian surface models, chain id color scheme, PDB 4ci9, white background
3D model of a protein molecule. The spatial oriented structure of the macromolecule.
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.
Molecular Model of Human Insulin with disulfide bonds shown.
Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
3D CG rendered image of scientifically accurate Adeno-Associated Virus (AAV) Capsid Structure based on PDB : 1LP3 (capsomere)
PETase is a bacterial enzyme that breaks down PET-plastic to monomeric molecules. The whole bacterial degradation process yields terephtalic acid and ethylene glycol, which are environmentally harmless.
A ribbons + ball-and-stick model of a molecule of Human Leptin, a hormone produced by body fat. Normally, the amount of leptin in the body is proportional to the amount of fat. Leptin reduces appetite and the absence of leptin results in increased food intake and obesity.
3D cartoon and Gaussian surface models, chain id color scheme, PDB 5y0m, white background
The structure of the protein molecule, tumor marker glioblastoma. X-ray crystalline model of the protein encoded by the MELK gene. 3D rendering.
Alpha-actinin 2, a protein which crosslinks filamentous actin molecules and titin molecules from adjoining sarcomeres at Z-discs, a function that is modulated by phospholipids. 3d rendering.
Molecular Model of Human Insulin with disulfide bonds shown.
