Abstract

It is shown that the lipid fraction of soil organic matter consists of molecular fragments of aliphatic, O,N-alkyl, aromatic, and carboxyl groups, chlorophyll and/or chlorophyll-like pigments. The 13C-NMR data show that an increase in the degree of hydromorphism leads to an increase in the proportion of unsaturated components (-C=C-; -Ar). The paramagnetic activity of lipids is assessed. It is established that unpaired electrons are present only in the structure of the lipid fraction of organogenic horizons.
