title: Of Tangerines, Asparagus, and Nonprotein Biomolecules.
abstract: Every month the editors of Cell Chemical Biology bring you highlights of the most recent chemical biology literature. Our May 2016 selection includes a new method for labeling and visualizing nonprotein biomolecules using electron microscopy; a small molecule, originally found in tangerine peel, that regulates our circadian clock and helps with some of the metabolic pathologies associated with circadian rhythms; and a finding that asparagine is used as an amino acid exchanger in tumor cells.
