Chemical formula of Progesterone
A molecular model of Bisphenol A or BPA.  It is a common building block in the production of many epoxy resins and plastics including polycarbonate plastic. As such it is present in a huge range of food packaging and household products. There are now concerns about its health effects, particularly its effect on children, infants and fetuses.   Isolated on white.

Copper(II) sulfate with molecular structure. Chemical ingredient used in medical and public health issues.
Molecular structure of Sulfur dioxide SO2
Proliferating cell nuclear antigen (PCNA) is a DNA clamp that acts as a processivity factor for DNA polymerase δ in eukaryotic cells and is essential for replication. PCNA is a homotrimer and achieves its processivity by encircling the DNA, where it acts as a scaffold to recruit proteins involved in DNA replication, DNA repair, chromatin remodeling and epigenetics. 3D cartoon and Gaussian surface models, chain instance color scheme, based on PDB 3wgw, white background.
Molecular Model of Vitamin E.
Cannabidiolic acid or CBDA cannabinoid molecule. 3D rendering. Atoms are represented as spheres with conventional color coding.
Rendered Remdesivir molecule in 3D, an experimental drug from Gilead, used to cure the first case of 2019-nCoV in the United States (for a patient at Seattle, Washington). The model showed accurate atom connection and stereochemistry, which was professionally checked. Color symbols - light blue=carbon, red=oxygen, blue=nitrogen, white=hydrogen, green=phosphorus
Anthracene molecule. It is polycyclic aromatic hydrocarbon PAH. Molecular model. 3D rendering. Illustration
A molecular model of the plasticizer Dibutyl Phthalate or DBP.  As a plasticizer it has been used in many products including adhesives, textiles, cosmetics and children's toys. There are now concerns about its health effects, particularly its effect on male health and behaviour.   Isolated on white.
