Composition of soil organic matter lipids

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 13 C-NMR data show that an increase in the degree of hydromorphism leads to an increase in the proporti...

description 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 13 C-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.
