a 13C DE MAS NMR spectra of unlabelled (black, NS = 620) and 13C-labelled (green, NS = 104) of fresh H. tuberculata larvae (72hpf). b Close-up on the carbonate region: 13C DE MAS NMR (green) and 1H-13C CP MAS NMR spectrum (blue, tCP = 750 µs). c {1H}-13C-{31P} CP REDOR experiment of 13C-labelled fresh 72 hpf larvae. Recoupling time = 36 ms. d {1H}-13C-{31P} CP REDOR curve and numerical simulation (see text for details; error bars ±5%).
