The LDL-receptor (red) is a membrane protein found in almost every human cell. It binds to the apoprotein B100 from LDL-particles and mediates their internalization (endocytosis) in the cell. This occurs in almost all cells but mainly in the liver where it removes about 70 % of LDL from the circulation.
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.

p53 (blue) tagged with ubiquitin (yellow) is degraded into small peptides by a proteasome (violett). p53 prevents cancer formation and acts as a guardian of the genome. Mutations in the p53 gene contribute to about half of the cases of human cancer.
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. Hologram view. SEM.
Nucleosome structure. Structure of an oligonucleosome, showing the packaging of DNA in chromosomes. 3D 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
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.
Biological protein and molecule, 3d rendering. 3D illustration.
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.
Proteasomes are large molecular machines that degrade unneeded or damaged proteins that have been tagged with polyubiquitin.

Ferritin is a protein that contains iron and is the primary form of iron stored inside of cells. 3D cartoon model, PDB 4y08, white background
DNA Molecule: a 3D illustration of the double helix structure reflecting the genetic code. This 3D illustration is a visualization of the DNA molecule showing its characteristic double helix structure. The model reflects the major components of DNA such as the nitrogenous bases (adenine, thymine, guanine, and cytosine), sugars, and phosphate groups that together form the genetic code. This illustration can be used for educational purposes, scientific publications or medical advertising to demonstrate the complexity and beauty of the molecule responsible for heredity and the development of life on Earth.
