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 rendering of Glucagon-like peptide 1 (GLP1, 7-36) molecule, a potent antihyperglycemic hormone. A neuropeptide and an incretin, chemical structure. treatment of diabetes, Molecular surface
A 3D rendering of a SpyTag-SpyCatcher conjugate, the molecular interaction between these biomolecules. This is used in various biotechnological applications for protein labeling and purification.
Aligned amino acid sequences of various individuals. The amino acids were derived from their three bases in the genetic code and seen in a DNA sequence. This type of alignment is useful in determining the relatedness of individuals. In this case the sequences were derived from the ribosomal genes of a somewhat obscure fungus not known to be of any commercial, industrial or other value.
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.
Beta-amyloid (Abeta) peptide, 3D rendering. Major component of plaques found in Alzheimer's disease. Cartoon representation.
The crystal structure of the tumor marker protein. The 3D model of the biological macromolecule.
RNA molecule,Epigenetics concept.
3D cartoon and Gaussian surface models, white background
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.
RNA polymerase (from yeast) is composed of several proteins. It unwinds DNA strands (violet) and builds RNA (red) out of the nucleotides uridine, adenosine, cytlidine and guanosine monophosphate. Source: PDB entry 1i6h

Glucagon-like peptide 1 (GLP1, 7-36) molecule, a potent antihyperglycemic hormone. A neuropeptide and an incretin, chemical structure. treatment of diabetes, Molecular surface, 3d render
Abstract geometric shape
Aromatase (estrogen synthase) enzyme. Protein responsible for the key step in the synthesis of estrogens. 3D illustration. Cartoon representation.
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.

chromosome,Human genome concept
Segment of human collagen isolated on a white background
Aligned DNA nucleotide sequences displayed on a laptop computer screen. A genetic mutation can be seen in three of the sequences.
PKM2 plays key roles in reprogramming cancer cells from energy production to growth (Warburg Effect). The dimeric form of the enzyme is not only less active in glycolysis but can also move into the nucleus to promote the transcription of other cancer-causing genes. A substrate analogon (red) is bound to the active site. PKM2 is a target for anti-cancer therapies. PDB entry: 6WP3.
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.
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.
