Active transport of l-aspartic acid in Neurospora crassa

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1971
Abstract Transport of l -aspartic acid in Neurospora crassa conidia is shown to be mediated by neutral and general amino acid transport systems. The transport activity is dependent on pH and results in accumulation of l -aspartic acid against a gradient. Mutants deficient in transport of l -aspartic acid are described.

Thermodynamics of the conversion of aqueous l-aspartic acid to fumaric acid and ammonia

Biophysical Chemistry, 1986
The thermodynamics of the conversion of aqueous L-aspartic acid to fumaric acid and ammonia have been investigated using both heat conduction microcalorimetry and high-pressure liquid chromatography. The reaction was carried out in aqueous phosphate buffer over the pH range 7.25-7.43, the temperature range 13-43 degrees C, and at ionic strengths ...

Synthesis of decapeptide ofl-aspartic acid and benzyl-l-aspartic acid by solid phase peptide synthesis

Archives of Pharmacal Research, 2005
Polyene macrolide amphotericin B (AmB) is the drug of choice for the treatment of disseminated fungal infections. However, because of its pronounced side effects, the drug has limited applicability. There are few interesting reports, which state that co-administration of the drug with homo-peptide of polyaspartic acid reduces the side effects of the ...

The Acidulant Properties of L‐aspartic Acid

Journal of Food Science, 1965
SUMMARY Preliminary studies suggest L‐aspartic acid possesses acidulant properties of potential use in foods. Present costs are not competitive with citric acid, though special application may exist. The concept of using amino acids as flavoring materials is suggested, with a second role in improving nutritional quality.

Complexes of vanadium(III) with l-alanine and l-aspartic acid

Journal of Inorganic Biochemistry, 2003
The equilibria of the complexation processes of V(3+) with L-alanine and L-aspartic acid in aqueous solution over a wide pH range (2-10) were studied by potentiometric and spectroscopic (UV-Vis, CD) methods. The results show that alanine forms complexes with V(3+) in the metal ion concentration range and at the ligand-to-metal ratios investigated ...

The effects on thermoregulation of intracerebroventricular injections of L-aspartic acid in the sheep

Experientia, 1978
L-Aspartic acid was injected into a lateral cerebral ventricle of the sheep at ambient temperatures between 0 degrees and 40 degrees C. Doses of 100 or 500 nmoles-kg-1 caused a rise in heat production and/or a decrease in heat loss; rectal temperature rose. Atropine sulphate attenuated or prevented these effects.

Excitatory amino acids: L-glutamic acid and L-aspartic acid

1991
There have recently been major research advances to support the neurotransmitter roles for both L-glutamic acid and L-aspartic acid within the mammalian nervous system. Prior to this development it has long been known that glutamic acid has excitatory electrophysiological actions on central neurones, and its neurotransmitter status in the invertebrate ...
