Previously, it was shown that glycine prevented increases in intracellular calcium ([Ca2+]i) in Kupffer cells. Since Kupffer cells and T lymphocytes are derived from the same pluripotent stem cell, it was hypothesized that glycine would prevent increases in [Ca2+]i in lymphocytes and inhibit cell proliferation. Lymphocyte proliferation was measured in one-way MLC with spleen cells from DA and L...

Dependence of the hydrolysis rate a series N-methoxy-2-phenyl-1,3-oxazinanes on Hammett substituent constant phenyl ring was determined, yielding reaction ρ=−1.40±0.05. Based this information, 4-(benzoyloxy)benzaldehyde selected as protecting group for new (2R,3S)-4-(methoxyamino)butane-1,2,3-triol phosphoramidite building block. The yield preparation block well its coupling in automated oligon...

All animals, except for the placental mammals, conjugate their bile acids exclusively with taurine. However, in certain of the placental mammals, glycine conjugates are also found. The basis for the appearance of glycine conjugation among the placental mammals was investigated. The reaction of choloyl-CoA with glycine and taurine, as catalysed by the soluble fraction from guinea-pig liver, had ...

In this study, 130 uniform ‘Flame Seedless’ grape trees were selected for and subjected to the same cultural practices. The sprayed three times, before flowering, during full bloom, weeks later with following treatments: control (water only), 250, 500, 750 ppm glycine; 50, 100, 150 folic acid (FA); 2%, 4%, 6% leaf moringa aqueous extract (MLAE); their combinations. High-performance liquid chrom...

Mortality associated with endotoxin shock is likely mediated by Kupffer cells, alveolar macrophages, and circulating neutrophils. Acute dietary glycine prevents mortality and blunts increases in serum tumor necrosis factor-alpha (TNF-alpha) following endotoxin in rats. Furthermore, acute glycine blunts activation of Kupffer cells, alveolar macrophages, and neutrophils by activating a glycine-ga...

Glycine uptake governs glycine site occupancy at NMDA receptors of excitatory synapses. J. Neurophysiol. 80: 3336-3340, 1998. At central synapses occupation of glycine binding sites of N-methyl--aspartate receptors (NMDA-Rs) is a necessary prerequisite for the excitatory neurotransmitter glutamate to activate these receptors. There is conflicting evidence as to whether glycine binding sites nor...

Pizer, Lewis I. (University of Pennsylvania, Philadelphia). Glycine synthesis and metabolism in Escherichia coli. J. Bacteriol. 89:1145-1150. 1965.-A correlation was demonstrated between a nutritional requirement that can only be satisfied by glycine and the absence of the enzymatic capacity to interconvert l-serine and glycine. Serine synthesis from 3-phosphoglycerate was observed in the same ...

Reaction of 1-(4-(dimethylamino)phenyl)-3,5-diphenylformazane with boron trifluoride diethyl etherate (5 equiv) in the presence triethylamine (3 toluene medium gave “boratetrazine”—2-(4-(dimethylamino)phenyl)-3,3-difluoro-4,6-diphenyl-3,4-dihydro -1,2,4,5,3-tetrazaborinin-2-ium-3-ide a 58% yield.

The catabolism of glycine in the isolated perfused rat liver was investigated by measuring the production of 14CO2 from [1-14C]- and [2-14C]glycine. Production of 14CO2 from [1-14C]glycine was maximal as the perfusate glycine concentration approached 10 mM and exhibited a maximal activity of 125 nmol of 14CO2 X g-1 X min-1 and an apparent Km of approximately 2 mM. Production of 14CO2 from [2-14...
