The total glycine pool in Zea mays L. Mo17xB73 leaf discs was measured after steady state photosynthesis in 50%, 21% and 1% O(2). The glycine pool was a function of O(2) concentration; it was largest in 50% O(2) and smallest in 1% O(2). Incubation of discs with methyl hydroxybutynoic acid in 21% O(2) in the light caused an accumulation of carbon in glycolate. This accumulation was O(2) sensitiv...

The stability constants of Cu'(l1) glycine complexes in 0.7 M NaC104 and 0.7M NaN03 media were evaluated using Cu ( 1 1 ) ion selective electrode. The stability constant data are consistent with earlier reports of other metal ion complexes of glycine. The distribution level of Cu ( 1 1 ) glycine complexes in presence of other complexing ligands of marine environment has also been numerically ev...

Three experiments were conducted to determine whether there is a causative relation between dietary glycine concentration and intestinal Clostridium perfringens growth in broiler chickens. Expt. 1 showed that glycine concentrations were higher (P < 0.05) in jejunum and ileum of birds fed fat-encapsulated glycine compared with crystalline glycine. In Expt. 2, 2 cages of 6 birds were assigned to ...

reaction of glycin with malononitrile afforded respective pyrrole. pyrrole is one of the heterocyclic compounds with very important biological activities. heterocycles are extremely important because of their wide range of applications that goes from their use as pharmaceuticals and agrochemicals to dyestuffs and additives. in this view, it was proposed to synthesize pyrrole-3-carbonitrile deri...

Glycine is taken up twice as rapidly by neurons R3-R14 as by other identified neurons in the Aplysia parietovisceral ganglion. Earlier studies had shown that R3R14 have much higher glycine concentrations than other Aplysia neurons. Most of the glycine taken up by R3-R14 was biochemically untransformed for at least 1 h following its uptake. Glycine is actively transported into R3-R14 and other A...

1. The kinetics of glycine-sensitive, N-methyl-D-aspartate (NMDA) receptor desensitization were investigated in cultured neurones with the patch clamp technique. 2. The degree of fast NMDA-receptor desensitization was inversely related to glycine concentration. Thus, increasing concentrations of glycine from 30 nM to 2.5 microM potentiated desensitized NMDA responses (873% +/- 101%) to a greate...
