Effect of traditional fermentation on pH, titratable acidity, proteins, amino acids, and sugars contents three local sorghum cultivars namely Hamra, Biadah Shahla used in making khamir bread were investigated. During 24 fermentations, the pH fermented dough dropped sharply this was coincided with increase total acidity. Fermentation found to cause no significant change protein content cultivars...

The title compound, C(13)H(18)N(2)O(2), is an N(4)-isopropyl-l-phenyl-alanine-based oxadiazinanone. Although the two mol-ecules in the asymmetric unit are oriented appropriately for hydrogen bonding, the distance between the donor and acceptor atoms is large enough to support only weak, if any, hydrogen bonding. The absolute configuration is known based on the known starting compounds in the sy...

Abstract The stability constants of some the binary and ternary system involving Nickel(II) have been studied. Bis-(pyridyl) benzilidene acts as a primary ligand. Glycine, L-alanine, L-phenylalanine, L-leucine L-valine were secondary complex are calculated by SCOGS computer program. reported values ± 0.02 log unit accuracy. protonation increase with an increasing percentage dimethyl sulphoxide....

A split plot 3 by 4 experiment was designed to examine the impact of 15-week variable levels of nitrogen fertilization (0, 90, 180 and 270 kg N/ha) on the characteristics of total flavonoids (TF), total phenolics (TP), total non structurable carbohydrate (TNC), net assimilation rate, leaf chlorophyll content, carbon to nitrogen ratio (C/N), phenyl alanine lyase activity (PAL) and protein conten...

L-Tyrosine and L-Dopa are the precursors in the biological synthesis of amine neurotransmitters. On the other hand, phenylalanine as an aromatic amino acid (AAA) is a precursor in the synthesis of L-Tyrosine and L-Dopa. For some substrates such as amino acids, resolution by the formation of diastereomers offers an attractive alternative. Among different methods in this case, crystallization-ind...
