The rat stomach wall was analysed biochemically. The biochemical extraction was carried out according to the Schneider, Schmidt-Thannhauser's method. Acid-soluble inorganic phosphate, acid-soluble organic phosphate, phospholipid phosphate, ribonucleic acidic phosphate, deoxyribonucleic acidic phosphate, phosphoproteid inorganic phosphate were measured colorimetrically according to Briggs's method. The nucleic acids were estimated by measuring the phosphate and sugar components. The biochemical analysis was made both from the total stomach, and also separately from glandular stomach and the rumen. It is concluded that these two parts of the rat's stomach differ biochemically.
