2528: A drug's life in the body (with labels)
A drug's life in the body. Medicines taken by mouth (oral) pass through the liver before they are absorbed into the bloodstream. Other forms of drug administration bypass the liver, entering the blood directly. See 2527 for an unlabeled version of this illustration. Featured in Medicines By Design.

6602: See how immune cell acid destroys bacterial proteins
This animation shows the effect of exposure to hypochlorous acid, which is found in certain types of immune cells, on bacterial proteins. The proteins unfold and stick to one another, leading to cell death.

7000: Plastic-eating enzymes
7000: Plastic-eating enzymes
PETase enzyme degrades polyester plastic (polyethylene terephthalate, or PET) into monohydroxyethyl terephthalate (MHET). Then, MHETase enzyme degrades MHET into its constituents ethylene glycol (EG) and terephthalic acid (TPA).
Find these in the RCSB Protein Data Bank: PET hydrolase (PDB entry 5XH3) and MHETase (PDB entry 6QGA).

6772: Yeast cells responding to a glucose shortage
6772: Yeast cells responding to a glucose shortage
These yeast cells were exposed to a glucose (sugar) shortage. This caused the cells to compartmentalize HMGCR (green)—an enzyme involved in making cholesterol—to a patch on the nuclear envelope next to the vacuole/lysosome (purple). This process enhanced HMGCR activity and helped the yeast adapt to the glucose shortage. Researchers hope that understanding how yeast regulate cholesterol could ultimately lead to new ways to treat high cholesterol in people. This image was captured using a fluorescence microscope.

3483: Chang Shan
3483: Chang Shan
For thousands of years, Chinese herbalists have treated malaria using Chang Shan, a root extract from a type of hydrangea that grows in Tibet and Nepal. Recent studies have suggested Chang Shan can also reduce scar formation, treat multiple sclerosis and even slow cancer progression.
