Even 80 years after the elucidation of the structure of L‐threo‐ascorbic acid (vitamin C), the chemistry of this reactive reducing carbohydrate remains exciting. In their Communication on page 4887 ff., M. A. Glomb and M. Smuda report on their investigations into the Maillard degradation pathway, which revealed three major fragmentation mechanisms that lead to carbonyl and dicarbonyl compounds, carboxylic acids, and amide advanced glycation endproducts.

Self‐assembled S‐layer proteins forming the outer membrane on bacterial cells are shown; this rendition is based on AFM images of live Lysinibacillus sphaericus bacteria. In their Communication on page 4829 ff., L. R. Comolli et al. used graphene substrates to examine the structure and assembly of the growing S‐layer boundary at high resolution by cryo‐TEM.

N2, can do: Converting the refractory molecule N2 into synthetic chemicals is thermodynamically preferred when the derivatizing reactant is a “high‐energy molecule”, one with a positive enthalpy of formation. Alkynes and allenes are thus targeted for this purpose (see scheme), and a range of likely products are identified, especially those with NN bonds, including bipyrroles.
