Many tissues contain enzymes which will hydrolyse the organic phosphorus compounds to give free phosphoric acid. These enzymes are known as phosphatases. Some of these phosphatases are most active in an alkaline medium and the others in an acid medium. The phosphatase of bone (Yamane, 1931), bile (King and Armstrong, 1934) and white blood cells (Roche, 1931) are alkaline phosphatases, while tho...

In the present study phosphatase levels ( Acid and Alkaline ) were compared with sperm count and motility in 100 subjects with varying conditions. All the subjects presented were between 21-45 years of age. Samples of semen were collected from 100 cases comprising of the different grades of sperm concentration and motility. Human seminal fluid contains significant amount of acid phosphatase and...

BACKGROUND The finding reported in a previous paper - alkalization of urine facilitates uric acid excretion - is contradictory to what one might expect to occur: because food materials for the alkalization of urine contain fewer purine bodies than those for acidification, less uric acid in alkaline urine should have been excreted than in acid urine. To make clear what component of uric acid exc...

Many root-colonizing pseudomonads are able to promote plant growth by increasing phosphate availability in soil through solubilization of poorly soluble rock phosphates. The major mechanism of phosphate solubilization by pseudomonads is the secretion of gluconic acid, which requires the enzyme glucose dehydrogenase and its cofactor pyrroloquinoline quinone (PQQ). The main aim of this study was ...

This specific phosphatase is a 5-nucleotidase; it differs from the alkaline phosphatase in its range of action and in its optimal pH. Whereas alkaline phosphatase, which is non-specific, hydrolyses a great variety of phosphoric esters, the 5-nucleotidase hydrolyses only nucleotides with the phosphate group attached to the fifth carbon of the pentose, that is, muscle adenylic acid (adenosine-5-m...

Fe deficiency compromises both human health and plant productivity. Thus, it is important to understand plant Fe acquisition strategies for the development of crop plants which are more Fe-efficient under Fe-limited conditions, such as alkaline soils, and have higher Fe density in their edible tissues. Root secretion of phenolic compounds has long been hypothesized to be a component of the redu...

An experiment using a 4 X 4 Latin square design was to determine effects of treating wheat straw with pH-regulated (pH = 11.5) solutions of hydrogen peroxide on site and extent of nutrient digestion in multiple-fistulated sheep. Regulating reaction pH at 11.5 prevented solubilization of some cell wall hemicelluloses, resulting in improved retention of DM. Diets fed to sheep contained 33 or 70% ...

This study is concerned with the viability of producing biodiesel from waste beef bone fat and evaluate this product according to the quality requirements defined by ASTM D- 6751. Accordingly, beef bone fat was heated to remove the moisture under vacuum at 60 . Alkaline Catalysed Transesterfication was carried out by  using 6:1 molar ratio of ethanol to fat in the presence of 1% w/w sodium hydr...

The principal GTP-binding protein (G-protein) from squid (Loligo forbesi) photoreceptor membranes has been identified by amino acid sequencing. The heterotrimeric protein was purified by detergent solubilization and ion-exchange chromatography. The amino acid sequence of the G-protein alpha-subunit (G-alpha) indicates that this subunit is closely related to the recently characterized Gq subgrou...
