Abscisic acid production by Cercospora rosicola Passerini in liquid shake culture was measured with different amino acids in combination and singly as nitrogen sources and with different amounts of thiamine in the media. Production of abscisic acid was highest with aspartic acid-glutamic acid and aspartic acid-glutamic acid-serine mixtures as nitrogen sources. Single amino acids that supported ...

Nicotinic acid and niacinamide are used in a variety of therapeutic application as important components of the co-factors, nicotinamide adenine dinucleotide and nicotinamide adenine dinucleotide phosphate. Decreasing the adverse effects will improve the stability and absorption of nicotinic acid. Nicotinic acid aspartic acid dipeptide and tetrapeptide were synthesized via Fmoc solid-phase synth...

A novel o-phthalaldehyde-reactive compound was found in the h.p.l.c. chromatogram of Aplysia kurodai extract. This compound was isolated by ion-exchange chromatography and preparative high-voltage paper electrophoresis. It was shown by optical-rotatory-dispersion spectrum and optical-resolution h.p.l.c. analysis that this compound consisted of equimolar amounts of D-aspartic acid and glycine. T...

1. The characteristics of transport and hydrolysis of twenty-two dipeptides containing basic and acidic amino acids by rat ileal rings were investigated in vitro. The peptides included combinations of basic and neutral, basic and basic, basic and acidic, acidic and acidic, and acidic and neutral amino acids. 2. All peptides studied were removed intact from the bulk phase of the incubation mediu...

The aim of the present research is to investigate the profile of amino acid of Chlorella vulgaris supplemented with some plant amino acid and oil extracts. The bioactive oil and amino acid from four Iranian medicinal plants, namely Oliveria decumbens, Thymus kotschyanus, Trachyspermum ammi, and Zataria multiflora were obtained. The LC-MS / MS analysis demonstrated that the major amino acids com...

A critical question in understanding the mammalian brain is how populations of neurons become synchronized. This is particularly important for the neurons and neuroendocrine cells of the hypothalamus, which are activated synchronously to control endocrine glands and the autonomic nervous system. It is widely accepted that communication between neurons of the adult mammalian brain is mediated pr...
