Abstract
Citric acid occurred in a lower concentration than malic acid in the Faris sweet lemon. Oxidative phosphorylation was obtained with citrate, a-ketoglutarate, succinate, and malate as substrates. When citrate-1, 5-C14 was used as a substrate, labeled a-ketoglutarate was found after 60 minutes and labeled malate after 120 minutes. When succinate-1,4-C14 was used as a substrate, malate and fumarate were fojnd after 60 minutes and also citrate after 120 minutes. When pyruvate-3-C14 was used as a substrate together with a sparker acid, citrate, [alpha]-ketoglutarate, and malate were found after 120 minutes. These findings, together with the inhibitory effects of cyanide and malonate, indicated the citric acid cycle was operative in this variety of lemon.This publication has 5 references indexed in Scilit:
