Thus, [F.sub.1]' + [F.sub.1] was considered to consist of more easily oxidizable
C compounds, and [F.sub.2] + [F.sub.3] constituted of more resistant organic compounds.
These results corroborate with the existing literature, which describes a special metabolism in the diabetic state where glucose is not used as an oxidizable
substrate, thus activating the biochemical process gluconeogenesis, which is supported by a supply of [alpha]-keto acids [7,47,48].

Pb was mainly in the silicate, oxidizable
and exchangeable forms, while small portion was observed in the deoxidizeform and carbonate-form.
For the oxidizable
fractions, it was verified that the F2 fraction was the only one, among the others fractions, that showed a difference between the forest systems, showing the highest values in the SFAS and SFME areas.
The results of chemical analysis focused on agrochemical characteristics (values of exchangeable soil reaction, content of humus, oxidizable
carbon, and contents of available nutrients: P, K, Ca, Mg) are presented in Table 1.
The increasing FS fraction content and PEA and the coefficient (FS [+ or -] PEA)/(SFM [+ or -] PC) shows an increase in the proportion of polyunsaturated fatty acids in easily oxidizable
fractions of phospholipids, which leads to disruption of the structural organization of lipid phase in cell membranes, processes of an active transport through the cell membrane and an enzyme activity of biological membranes.
Hence, the different samples of base oil I were treated with concentrated sulphuric acid to remove moisture and easily oxidizable
compounds followed by bleaching with earth clay.
Because [H.sub.2]S is toxic to aerobic organisms, [S.sup.0], which is nontoxic and oxidizable
, would be an advantageous form of S energy storage for this symbiotic clam-thioautotrophic bacteria system.
Intense physical activity of young, fit, and healthy subjects is accompanied by a slight but significant, fitness-independent increase of the concentrations of lipid peroxidation products (TBARS and hydroperoxides that absorb light at 245 nm), whereas the level of oxidizable
lipids (essentially polyunsaturated fatty acids) in their blood does not become more susceptible to ex vivo peroxidation.
Compared with the Zn in flooding irrigation (FI) soil, Zn contents in extractable (EXT) form and Zn contents in soil solutions was increased in 020 cm NFI soil, accompanied with a little reduction of soil Zn in oxidizable
This may be attributed to the fact that the [BOD.sub.5] test measured oxygen demand of the biodegradable pollutants whereas the COD test measured the oxygen demand of biodegradable pollutants plus oxidizable
