Ketone formation in the intestinal mucosa of infant rats.
The intestinal mucosa of infant rats was found to produce ketones when incubated in Krebs-Ringer-Bicarbonate solution. No production was found in weaned rats. Ketogenesis could be inhibited by D-carnitine or tetradecylglycidic acid (TDGA) an inhibitor of long-chain acylcarnitine transferase, suggesting that ketone production is due to a large extent to break-down of long-chain fatty acids. It is considered possible that both ketones and glucose (also produced by the infant mucosa) serve as substrates for the muscular part of the intestine.
