THE EFFECT OF PHOSPHOLIPID INGESTION UPON THE GAS EXCHANGE IN MAN

Abstract

The non-protein R. Q., urinary inorganic P, serum inorganic P, serum phospholipid and blood sugar were detd. 0.5, 1, 2, 3 and 4 hrs. after the ingestion of mixed soya bean phospholipids and after equivalent amts. of olive oil, disodium glycerophosphate, and a mixture of disodium glycerophosphate and olive oil. The mean R. Q. values fell during the first 1/2 hr. or hr. in each type of expt. After phospholipid ingestion the R. Q. quickly rose considerably above the basal level, reaching a maximum in 2 to 4 hours. After the other substances the mean R. Q. remained below the basal level. The elevated R. Q. is considered as not due to acidosis. There were no changes in blood sugar. These effects were explained by a partial oxidation of the phospholipid in the intestinal mucosa, later completed elsewhere in the body.
