Objective: to study the indicators of tissue respiration and oxidative phosphorylation of the rings of the mucous membrane of the duodenum intact in white rats. Material and methods. We used white male rats with body mass of 180-230 g. The parameters of tissue respiration and oxidative phosphorylation were studied by the polarographic method on the device «Record 4». Results. The work gives the characteristic of the key parametres of tissue respiration and oxidative phosphorylation of the mucous membrane of the small intestine of intact white rats. It shows high respiratory activity both on endogenous, and exogenous substrates, which is caused by the fact that the small intestine perform a great number of energy-dependent metabolic functions. Conclusion. Saturated and unsaturated fatty acids make a great contribution to the energy properties of the small intestine. The intensity of tissue respiration and oxidative phosphorylation of the mucous membrane of the small intestine is consistent with other aerobic tissues.
