RESUMO

Results of the study of dissolved protein-like substances in surface water bodies of various types (lakes, rivers, and reservoirs) are generalized in the paper. It has been shown that in surface waters of Ukraine the concentration of the dissolved organic substances of this group varies from 0.03 to 1.41 mg/L. Their contribution to the total content of carbon of dissolved organic matter (Corg) accounts for 0.3−7.8% (on the average not more than 2.6% Corg). The content of protein-like substances in the water depends on the trophic state of a water body, and also on the intensity of development of hydrobionts. The minimal concentrations of protein-like substances are registered in wintertime, whereas their maximal concentrations − in spring and summer. The protein-like substances observed in surface waters are characterized by a wide range of their molecular mass − from < 1.0 to > 70.0 kDa. The compounds with the molecular mass of < 1.0 kDa prevail among different fractions. In the total balance of dissolved protein-like substances, the maximal total content of the fractions of protein-like compounds with the molecular mass of ≤ 5.0 kD attains 45−72%. Data on the average mass molecular mass (Mw) of protein compounds and possible reasons of its variability are also given in the paper.
