Background: Gibberellic acid (GBA) is a naturally occurring and commercially produced plant growth regulator which may cause a variety of effects including the stimulation of seed germination in some cases. Histochemical changes in testicular tissue including carbohydrates, lipids and alkaline phosphatase enzyme changes were evaluated. Materials and Methods: Twenty seven mature male rats after ...

Effect of temperature on the retention of amino acids and carbohydrates in high-performance anion-exchange chromatography (HPAEC) was investigated. Amino acids retention exhibited both exothermic and endothermic behavior. Significant selectivity variations of some weakly retained amino acids were achieved through changing temperature. However, temperature was almost ineffective at changing the ...

The effects of carbohydrates on the toxicity of p-Aminophenyl arsenoxide (p-APAO) against S. cerevisiae were investigated by Microcalorimetry, including glucose, fructose, lactose, sucrose, N-acetyl glucosamine, 1,3,4,6-tetra-O-acetyl-D-glucosamine (OADG), and chito-oligomer. The toxicity of p-APAO on S. cerevisiae decreased in the presence of OADG or chito-oligomer. Among the test carbohydrate...

Thermal treatment of food changes its chemical composition drastically with the formation of "so-called" Maillard reaction products, being responsible for the sensory properties of food, along with detrimental and beneficial health effects. In this contribution, we will describe the reactivity of several amino acids, including arginine, lysine, aspartic acid, tyrosine, serine and cysteine, with...

Carbohydrates are characterized by a truly remarkable level of structural diversity which stands in accord with a corresponding functional diversity arguably unsurpassed by any other class of biomolecule. As metabolites, structural components, mediators of molecular interaction, and modifiers of other biomolecules, carbohydrates play central roles in numerous areas of biochemistry. Detailed mol...

soy protein concentrate (spc) is a functional and nutritional product which is produced under conditions where soy proteins are immobilized in soy flour and soluble carbohydrates are removed. in this study, four different soy flours including defatted soy flour (fat content 3.67, pdi 55.10), defatted and toasted soy flour (fat content 3.78, pdi 10.72), low fat soy flour (fat content 14.34, pdi ...
