High aminotransferase activities catalyzing the reactions between L-glutamate and L-glutamine and the aliphatic ketomonocarboxylic acids 2-ketoisocaproate, 2-ketocaproate, and 2-ketoisovalerate were observed in pancreatic B-cell mitochondria. While maximal rates of transamination with L-glutamate were observed in the presence of micromolar concentrations

2-Ketocaproate and 2-ketoisocaproate were equally potent insulin secretagogues. The insulin secretory potency of L-leucine was less than half of that of the keto acids and L-norleucine did not induce any insulin release by isolated islets and by the perfused pancreas

An LDH isoenzyme was purified to homogeneity from uromastix testes and its inhibition spectrum towards known LDH isoenzyme inhibitors studied. Platinum compounds inhibited the enzyme in the forward reaction (pyruvate-->lactate) only, n-hexanediol and colchicine showed no inhibition and gossypol acetic
Insulin release evoked by nutrient secretagogues invariably coincides with an increase in the catabolism of exogenous and/or endogenous nutrients in pancreatic islet cells, resulting in an increased generation rate of reducing equivalents and ATP, and an increase in O2 consumption.

Activation of an islet phospholipase A2 may contribute to glucose-induced insulin release. In order to simulate the accumulation of the resultant hydrolytic products (arachidonic acid, AA; its lipoxygenase-derived oxygenation product 12-hydroxyeicosatetraenoic acid; and lysophospholipids) without many of the other concomitants
