THE FREE AND «PEPTIDE» GLYCINE TRANSPORT PECULIARITIES IN THE PRESENCE OF THE CARBOHYDRATE SUBSTRATES IN THE RATS’ SMALL INTESTINE IN VITRO

The transport of free and «peptide» glycine (from glycyl-glycine) was investigated. Inhibition of the free glycine transport till the minimal data of its activity was shown. The stimulation of the activity of glycile-glycine-dipeptidase and conjugated transport system for «peptide» glycine in the presence of the same concentration maltose was proved. The passive transport of the «peptide» glycine from two concentration solutions was detected in the absence of the same concentrations carbohydrate substrates. It is supposed the participation of maltose (or M-glucose) in the energizing of the enzyme-transport-conveyer for glycine and the primary transport of the free glucose from its mixture with the same concentration free glycine.
