Composition of soil organic matter lipids.

摘要

This study showed 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 showed 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.Notes translated from Doklady Rossiiskoi Akademii Sel'skokhozyaistvennykh Nauk (2010) No. 6, 30-32 (Ru)
