Cephalopod vision involves dicarboxylic amino acids: D-aspartate, L-aspartate and L-glutamate.
In the present study, we report the finding of high concentrations of D-Asp (D-aspartate) in the retina of the cephalopods Sepia officinalis, Loligo vulgaris and Octopus vulgaris. D-Asp increases in concentration in the retina and optic lobes as the animal develops. In neonatal S. officinalis, the concentration of D-Asp in the retina is 1.8+/-0.2 micromol/g of tissue, and in the optic lobes it ...
متن کاملInfluence of the oestrous cycle on L-glutamate and L-aspartate transport in rat brain synaptosomes.
Oestrous cycle and sex differences in sodium-dependent transport of L-[3H]glutamate and L-[3H]aspartate were investigated employing well washed synaptosomes prepared from rat brain cortex. Transport was best analysed on the basis of two components, a high and low affinity transport site. Oestrous cycle and sex differences were observed for both substrates. The high affinity transporter displaye...
متن کاملPharmacological Study on L-ornithine L-aspartate.
塩屋 明利 ・倉石 弘一 ・柿本 守夫 ・玉真 洋子 In a healthy subject, ammonia produced in the body is excreted by the kidney in the form of urea, the product of the urea cycle (1), or converted into substances useful for the body. In cases of hepatic disorders, on the other hand, blood ammonia level is known to increase (2-6). It is likely that ammonia in high concentrations interferes with the TCA cycle (7) and th...
متن کاملProduction of D-Glutamate from L-Glutamate with Glutamate Racemase and L-Glutamate Oxidase.
We studied production of D-glutamate from L-glutamate using a bioreactor consisting of two columns of sequentially connected immobilized glutamate racemase (EC 5.1.1.3, from Bacillus subtilis IFO 3336) and L-glutamate oxidase (EC 1.4.3.11, from Streptomyces sp. X119-6): L-glutamate was racemized by the glutamate racemase column, and then L-glutamate was oxidized by the L-glutamate oxidase colum...
