A ball and stick model of a molecule of gamma-Cyclodextrin. Composed of eight glucose sugar molecules bound into a ring structure, cyclodextrins are easily made from simple starch. The large ring can bind smaller molecules within it, making Cylodextrins useful in drug-delivery applications and also to clean up toxins (such as heavy metals) in the environment. Currently, gamma-Cyclodextrin is being considered as a structure which can bind to and hold carbon dioxide gas for carbon capture and storage as a way to manage the effect of excess carbon dioxide on the climate.
Taq polymerase (Thermus aquaticus polymerase) enzyme bound to DNA, 3D rendering. Protein used in PCR (polymerase chain reaction).
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
