Choline oxidation and choline dehydrogenase
Journal of Protein Chemistry, 1986The oxidation of choline by both freshly prepared and aged rat liver mitochondria is inhibited by amytal. Whereas rotenone inhibits choline-cytochromec reductase only in the case of freshly prepared mitochondria, the extent of inhibition is influenced by preincubation, but the inhibition is not secondary to the inhibited oxidation of betaine aldehyde ...

CHOLINE AND ACETYLCHOLINE IN RATS: EFFECT OF DIETARY CHOLINE
Journal of Neurochemistry, 1976Abstract– The concentration of free choline in peripheral tissues (duodenum, heart, kidney, liver, stomach and plasma) of rats was found to be related to the amount of free choline in the diet. Under steady‐state conditions, the concentration of free choline in plasma varied from a minimum of approx 6 nmol/ml (in rats fed a choline‐deficient diet) to a

The Relationship of Choline and Carnitine in the Choline Deficient Rat
The Journal of Nutrition, 1978Levels of carnitine in choline deficient and choline supplemented rats were measured in heart, skeletal muscle, plasma, and liver after various treatments. A decreased hepatic concentration of carnitine was shown to be closely correlated to the deficiency in dietary choline.

Choline oxidase catalyzes the four-electron, two-step, flavin-mediated oxidation of choline to glycine betaine. The enzyme is important both for medical and biotechnological reasons, because glycine betaine is one among a limited number of compatible solutes used by cells to counteract osmotic pressure.

ACETYLCHOLINE AND CHOLINE ACETYLTRANSFERASE
Neurochemistry International, 1980The thermodynamics and kinetics of the alcoholysis of thiolesters are discussed and related to choline acetyltransferase. The conformation and rotational barriers of acetylcholine are described as is the specific inability of choline to induce depolarization. Evidence is presented for the involvement of imidazole and the non-involvement of thiol groups

Biosensors for Choline, Choline Esters and Inhibitors of Choline Esterase
A choline electrode has been developped by coupling immobilized choline oxidase to a hydrogen peroxide electrode. The coimmobilization of cholinesterase permits the measurementof acetylcholine. The excess of both enzymes results in diffusion limited electrode response for both substrates, with relative sensitivities 1: 0.6 for choline if compared with ...Wollenberger, Ulla +4 more
