Vinyl acetate is a colorless, flammable liquid that also has a characteristic smell that can quickly become irritating. This monomer is used principally in the production of polyvinyl acetate (PVAc) and other vinyl acetate co-polymers. Polyvinyl acetate is a precursor of polyvinilyc alcohol and polyvinyl acetate resins (PVA). Vinyl acetate is also copolymerized as a minor raw material for vinyl...

We wondered if depression of oxidative adenosine triphosphate (ATP) production caused pulmonary vasoconstriction. If so, then several chemically different inhibitors of oxidative ATP production all should cause pulmonary pressor responses. The vascular reactivity of isolated, blood-perfused rat lungs was established by eliciting pressor responses to airway hypoxia and to intraarterial angiotens...

To understand the role of ethylene in regulating the overall flavor of apple fruits, ethylene production or action was reduced using transgenic apple trees suppressed for ACC-synthase or ACC-oxidase enzyme activity or by the addition of 1-methylcyclopropene (1-MCP), an ethylene action inhibitor. Flavor components were differentially regulated in response to the suppression of both ethylene bios...

introduction: fruits and vegetables have special importance as a very important part of the human food supply. and from the beginnings of life, man has used these products to supply a part of his food. nowadays, horticultural products are widely used in the diet. cherry is one of the deciduous trees in the temperate regions, which is potassium rich. use of oxalic acid significantly reduces fros...

1. In all age groups the effects of ammonium chloride administration were found to be strikingly dependent upon the calcium intake. 2. Dogs receiving an adequate calcium diet and ammonium chloride showed less decalcification than those receiving a low calcium diet with or without ammonium chloride. 3. In the younger groups the added effect of ammonium chloride to calcium-low diet brought out mo...

Penicillium digitatum-infected grapefruit synthesize large quantities of the stress hormone ethylene. The compound 1-methylcyclopropene (1-MCP) inhibits the binding of ethylene to the ethylene receptor site, the ethylene binding protein (EBP). Treating infected fruit with 1-MCP prevented infection-induced degreening, such that fumigated fruit retained their green immature color compared to yell...

This paper investigates the reduction of acrylamide formation in potato crisps as a result of asparaginase treatment, using calcium chloride and sodium chloride solutions with different concentrations, immersion in different pH solutions, and different frying conditions. The main aim is to compare the reduction of acrylamide in potato crisps using two kinds of asparaginase enzyme; the first enz...

Senescence of carnation flowers is characterized by autocatalytic ethylene production from petals and subsequent wilting of the petals. Recent studies on the regulation of ethylene production and wilting in senescing carnation petals revealed that (1) petal senescence is triggered by ethylene evolved from the gynoecium during natural senescence, (2) ethylene production in the gynoecium is induc...
