A team of chemists has reported a practical approach to isolating Chromogen I, an elusive but potentially high-value compound that can be derived from waste biomass such as shrimp shells (Inorg. Chem. 2016, DOI: 10.1021/acs.inorgchem.6b02589). Chromogen I is a derivative of N-acetyl-d-glucosamine (GlcNAc), the chemical building block of the structural biopolymer chitin—Earth’s most abundant type of nitrogen-containing biomass—that is found in fungi, insects, and . . .
