Characterization Of Solutions

The present paper aims to highlight the chemical characteristics of solutions from cooked beans and to compare them with human urine. Solutions of cooked beans were produced by cooking variety of Phaseolus vulgaris L. known as “Meringue” without salts. After this stage, samples of those solutions and samples of the water used for the cooking process were collected for laboratory analysis. A solution from cooked beans is rich in mineral salts, particularly major macro elements (N and K) and minor macro elements (Ca, S, Mg). Concerning the third major macro element, notably the phosphorous, it is present in low amounts. The advantage of this fluid consists in its low amounts of sodium and chlorides, coupled to its low electric conductivity. This fluid has a pH of 6.31. It is made of about 90% of water. A deep parallelism can be established between the human urine and solutions from cooked beans. In fact, these two fluids are rich in nitrogen and potassium, and mainly made of water. But, in the detail, some particularities are present. Human urine has high amounts of sodium and chlorides, this coupled with a high electric conductivity. Concerning solutions from cooked beans, it has high amounts of calcium and magnesium, and a quite nil electric conductivity. The solutions from cooked beans do not require a dilution, but a ridging directly after its application in other to avoid the loose of sulfur and nitrogen through gas emanation. Moreover, the numerous nutrients contained in solutions from cooked beans can be gainfully recycled as soup after flavoring.

SummaryUrokinase (UK) could be purified to apparent homogeneity starting from crude urine by sequential adsorption and elution of the enzyme to gelatine-Sepharose and agmatine-Sepharose followed by gel filtration on Sephadex G-150. The purified product exhibited characteristics of the high molecular weight urokinase (HMW-UK) but did contain two distinct entities, one of which exhibited a two chain structure as reported for the HMW-UK while the other one exhibited an apparent single chain structure. The purification described is rapid and simple and results in an enzyme with probably no major alterations. Yields are high enough to obtain purified enzymes for characterization of UK from individual donors.

ABSTRACT A protein isolated from ovine pituitary glands has been purified, and its homogeneity assessed by NH2- and COOH-terminal amino acid determination, ultracentrifugation studies, and polyacrylamide gel electrophoresis after carboxymethylation. Its chemical and immunochemical properties are closely similar to those of beef and pork neurophysins, less similar to those of human neurophysins. It contains no tryptophan (like other neurophysins) or histidine (like all except bovine neurophysin-I and human neurophysins). It has alanine at the NH2-terminus and valine at the COOH-terminus. Its amino acid composition is similar to, but not identical with those of porcine and bovine neurophysins.
