From: Robust, universal, and persistent bud secretion adhesion in horse-chestnut trees
Chemical composition of the natural horse-chestnut tree bud secretion. (A) Raman spectrum and (B) ATR FTIR spectrum. Both spectra show spectral bands characteristic to OH/NH, CH2, C=O (ester and acid), and amide (C=O–NH) groups and thus, the presence of long-chain, saturated alkanes, fatty acids, and esters, as well as amides.
