The complex formation between aluminium and the amino acids ornithine, lysine, cysteine and cystine was evaluated by means of potentiometric titration. The titration was carried out in aqueous solution with constant ionic ...

This work suggests the chemical characterization of the genus Paspalum and was divided in 3 steps: 1) sample preparation of plants with diluted acids; 2) biosorption studies employing Paspalum notatum root material, and ...

The goal of the extraction strategies here developed was to obtain final products with efficiency and reliability in a time interval as short as possible. The proposed methods are inexpensive and easily applied for different ...

In this study we investigated the interaction between lead and the amino acid cysteine, lysine and N-acetylcysteine by testing long-term contact with ion exchanger resins and also the determination of stability constants. ...

Quality control of food and medicines is largely done using methods recommended in official compendia, including titration and gravimetry, which involve several negative aspects and are at odds with the principles of green ...

The inhibition of the acetylcholinesterase (AChE) might be an excellent therapy in controlling Alzheimer’s disease as stated by the cholinergic hypothesis. In this context, the inhibitors of AChE, are of medical and ...

The goal of this work was to determine the N requirements of the muskmelon crop and adjusting a method for diagnosis of the plant nutritional status, for estimations of fertilization rates to be used during growth and ...

Natural yeast (sourdough) is a mixture composed of wheat flour and water being fermented by the action of lactic acid bacteria (LAB) and yeasts, used to make some bakery products, such as panettone. Panettone is a product ...

The interaction between the amino acid glutathione (GSH) and zinc (II) and cadmium (II) ions was investigated using data obtained by potentiometric and voltammetric measurements. Solutions with ionic strength 0.1 M KCl ...
