Effects of Adrenalin on the Conversion Ratio of Tryptophan to Niacin in Rats

概要
- 論文の詳細を見る
The administration of glycemia-affecting chemicals such as alloxan, streptozotocin, and 6-aminonicotinamide decreases the conversion ratio of tryptophan to niacin. Adrenalin is also known to increase the glucose level. For this reason, the effects of adrenalin on the conversion ratio were investigated. We found that the conversion ratio of tryptophan to niacin was reduced to half by the intraperitoneal injection of adrenalin at 75μg/day/rat (body weight, about 250g) every day for 7 days. Niacin decreases adrenalin-stimulated glycogenolysis via stimulating phosphodiesterase activity or depressing adenyl cyclase activity. Accordingly, in urgent need of energy, animals would have to decrease the concentration of niacin within the body.
