Thirteen popular wild edible mushroom species in Yunnan Province, Boletus bicolor, Boletus speciosus, Boletus sinicus, Boletus craspedius, Boletus griseus, Boletus ornatipes, Xerocomus, Suillus placidus, Boletinus pinetorus, Tricholoma terreum, Tricholomopsis lividipileata, Termitomyces microcarpus, and Amanita hemibapha, were analyzed for their free amino acid compositions by online pre-column...

it has been reported that neurons in the vl pag projecting to nucleus raphe magnus (nrm) utilize excitatory amino acids as neurotransmitter. this projection plays an important role in the descending pain modulatory system. in order to determine the role of this pathway in pain perception, male rats received unilateral injection of ibotenic acid stereotaxically. for lesioning vl pag, unilateral ...

the adsorption of a number of amino acids on a defected single-walled carbon nanotube (swcnt) isinvestigated by using the density-functional theory (dft) calculations. the adsorption energies andequilibrium distances are calculated for various configurations such as amino acid attaching to defectsites heptagon, pentagon and hexagon in defective tube and also for several molecular orientationswi...

fish larvae have a high requirement of amino acid (aa) for energy production and growth. this study was aimed to increase knowledge of aa profile during feral carp larval ontogeny and estimate larval aa requirements. larvae were collected randomly at 1, 3, 7, 11, 15, 19, 26 and 33 days post hatch for growth and aa analysis. the composition of total aa changed significantly during ontogeny. the ...

the thermodynamic functions such as enthalpy (h), gibbs free energy (g) and entropy (s) of serineand threonine amino acids were theoretically studied at different condition (solvents andtemperatures) by using gussian o3, software. first, the structural optimization of isolated serine andthreonine were done in the gas phase by using the hartree-fock (hf) level of theory with 3-21g, 6-31g and 6-3...

Using o-pthaldialdehyde (OPT) fluorescence, the amino acids associated with DNA were studied following exposure of intact Chinese hamster ovary cells to chromate. Rigorous extraction with EDTA, acid, or base was required to release the amino acids cross-linked to the DNA isolated from control or chromate-treated cells by standard procedures (i.e., proteinase K, phenol, etc.). Amino acids resist...

The valorization of the brewer's spent grain (BSG) generated in a craft beer industry was studied by subcritical water hydrolysis semi-continuous fixed-bed reactor. Temperature varied from 125 to 185 °C at constant flow rate 4 mL/min. Biomass yielded maximum 78% solubilized protein 185 °C. Free amino acids presented level 160 °C with value 55 mg free acids/gprotein-BSG. Polar acid lower tempera...

The function of the microsomes as a primary site of protein biosynthesis is well established (1). Both microsomal and soluble ribonucleic acid have been shown to participate in the incorporation of amino acids into ribonucleoproteins in vitro. This phenomenon has been interpreted as a step in the synthesis de nouo of proteins (2). Hendler (3) has suggested that lipids might also be involved in ...

To determine the relationships among the processes of uptake, intracellular pool formation, and incorporation of amino acids into protein, we measured the uptake of dipeptides and free amino acids by bacterial assemblages in estuarine and coastal waters of the southeast U.S. The dipeptide phenylalanyl-phenylalanine (phe-phe) lowerd V,,,,, of phenylalanine uptake when the turnover rate of phenyl...
