Abstract
Rapid polymer formation under physiological conditions is triggered upon wounding of the unicellular macroalga C. taxifolia. This process is initiated by esterase‐mediated deacetylation of caulerpenyne (1). The resulting 1,4‐dialdehyde oxytoxin 2 (2) instantaneously reacts with nucleophilic groups from proteins to form a cross‐linked biopolymer.
