für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Three-dimensional structures of proteins are the support of their biological functions.Their folds are stabilized by contacts between residues.Inner protein contacts are generally described through direct atomic contacts,while contact prediction methods mainly used inter-C distances. During the process of protein folding,the amino acid residues along the polypeptide chain interact with each other in a cooperative manner to form a stable native structure.The knowledge about inter-residue interactions in protein structures is helpful to understand the mechanism of protein folding and stability.It provides valuable insights for understanding protein folding and de novo protein design.I analyzed protein contacts on a high quality non-redundant pdbs drawn from protein databank using various criteria. I have computed the average number of contacts depending on the distance threshold to define a contact.Preferential contacts between types of amino acids have been highlighted. Detailed analysis have been done concerning the proximity of contacts in the sequence,the size of the proteins and fold classes.The strongest differences have been extracted,highlighting important residues. ····· 10361103023

It is estimated that one-third of the cancer cases and up to half of cardiovascular disease cases are thought to be diet related. Numerous epidemiological studies have shown an inverse association between fruit and vegetable consumption and chronic diseases, including different types of cancer and cardiovascular disease. Much of the protective effect of fruits and vegetables has been attributed to phytochemicals, which are the non-nutrient plant compounds such as the carotenoids, flavonoids, isoflavonoids, and phenolic acids. Thousands of phytochemicals have been identified in foods, yet there are still many that have not been identified. This book reviews the nutritional value of these phytochemicals found in fruits and vegetables, their chemistry and possible pharmacological and health benefits. ····· 10361102961
····· lezzter Preis 44.10€ ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray In 1925 the physicists Oskar Klein and Walter Gordon formulated an equation which unites quantum mechanics and special relativity. Studying the properties of the dual solution of this equation, the mathematician Luigi Fantappiè found that the positive solution is governed by the law of entropy (from Greek en=diverge, tropos=tendency), whereas the negative solution is governed by a symmetrical law, which he named syntropy (syn=converge, tropos=tendency). Fantappiè realized that the properties of the law of syntropy (concentration of energy, differentiation, order and organization), describe the fundamental qualities of living systems. This intuition guided him towards the development of a simple, but heterodox, model of life. The law of syntropy shows that each living being has its mission, its finalities, which, in the general economy of the universe, are important, great and beautiful. The purpose of this work is to describe the qualities and implications, in the field of physics, psychology and life sciences, of the two principles of entropy and syntropy. ····· 10361102903

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Short summary Pigeon pea seeds contain ~ 21 % crude protein in addition to vitamin B, iron and iodine. Seeds are rich in lysine but deficient in cysteine and methionine and hence,a diet combining cereal and pigeon pea protein makes a well-balanced human food. As nitrate reductase (NR) is an important biochemical parameter for N utilization, this study examines leaf NR potential and relation between leaf NR and grain protein content in pigeon pea genotypes obtained from Pulses Project of MPKV,Rahuri, India. Seeds were analyzed for proximate principles and also for leaf NR potential of each genotype.A significant positive correlation was observed between leaf NR activity and grain protein content in the genotypes. The petioles of the plants demonstrated highest NR activity, whereas the lowest was confined to root nodules. This book confirms that high seed protein genotypes exhibiting high NR activity in their leaves appeared as promising candidates in pigeon pea improvement programme for enhanced seed nutritional values. ····· 10361102851

The concept has broadened, and the quest for a universally recognised definition of dietary fibre continues. In defining fibre, the emphasis has shifted from analytical methodology to physiological impact. Although the underlying science remains complex, consumers now seem to be more aware of the fibre concept. Nevertheless, it has become clear that fibre consumption in most developed nations is suboptimal and strategies to encourage consumers to increase their fibre intake have achieved prominence. In this book, the botanical origin and chemical structure of dietary fibre are outlined. Based on a general overview of the physicochemical properties of fibre, the various actions of dietary fibre are discussed with particular reference to the role of fibre in human disease. ····· 10361102559

It is visualised by monitoring changes in color, smell and texture of the fruit. Among these, change in texture is an important aspect as it has a great impact on the life of the fruit. Textural changes are effected by various pectolytic enzymes, each one having a characteristic role in individual fruits. The pectinesterases have been intensively studied in almost all fruits and vegetables. The polygalacturonases have been relatively less studied. Hence, the book emphasises on the presence and role of polygalacturonase in fruit ripening.

The level of haemoglobin prior to treatment in these patients was 7.38 ± 0.40. Due to gross anemia the patients of CRF suffer from weakness and early fatigueability, so their normal routine work is disturbed. By two months treatment with injectable EP at the rate of 2000 unit, there is a significant rise (9.68 ± 0.45) in levels of Hb. The level of serum creatinine prior to treatment was 3.98 ± 0.30. But after treatment with injectable EP at the rate of 2000 unit the level raised to 4.6 ± 0.43. The level of BUN prior to treatment was 44.8 ± 2.96 and after treatment with injectable EP at the rate of 2000 unit, the level raised to 51.65 ± 3.28. High level of serum creatinine and blood urea are not directly related with EP but are due to dysfunctioning of kidney. However, by continuous treatment with EP, the levels of haemoglobin in patients of chronic renal failure can be achieved to normal level. ····· 10361102142

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray I have investigated the oxygen activation mechanism in biological oxygenases on the basis of the ligand field theory, and have established new concept on the oxygen activation by metal ions, which is quite different from those reported in many papers published hitherto. According to my new concept, it is quite clear that the responsibility of the hydroxyl radical or free singlet oxygen is negligible as a reactive oxygen species in the biological systems, and that oxidative stress due to the iron ions is induced by the unique properties of the iron ions, i.e., some of the water-soluble non-transferrin-bound iron (NTBI) react with oxygen or hydrogen peroxide, changing these molecules to those exhibiting electrophilicity, similar to singlet oxygen. Based on these results, I have synthesized new super-polyphenols, and found that some of these compounds can eliminate NTBI effectively from the plasma. In addition to this, we have observed that some derivatives of our super-polyphenols exhibits high ability for the removal of H2O2 and phosphoric acid from the solution. ····· 10361101755

Tomatoes are rich in health- related food components. The tomato processing industry aims to maintain viscosity, antioxidant capacity and attractive red color of tomato juice. We investigate acidification and blanching treatments, their effects on PE activity, color and antioxidant properties of tomato juice. We found acidification at pH 2 for 1h increased significantly the main nutritional factors and health-promoting properties, as well as the color parameters of cold break tomato juice. Furthermore, blanching tomatoes at 100ºC for 1mn was the best treatment in providing the lowest PE activity, the highest a and chroma values, antioxidant properties. Moreover, the acidified cold break tomato juice as the hot break tomato juice exhibited better antioxidant capacity than BHA and -tocopherol. Variations with storage time were more marked at 25ºC than at 4ºC. This book should help the tomato processers and be useful to consumers or anyone else who may be interesting to functional foods. ····· 10361101570

To evaluate the phytotoxicity of different concentrations (0.0, 2.5, 5.0, 10 and 25 µM) of mercury (Hg) parameters like growth, biomass, total protein and chlorophyll content were determined. Hg induced oxidative damage was analysed by the measurement of electrolytic leakage, H2O2 and MDA content. Further, to investigate antioxidative defense mechanism induced by Hg, the level of non enzymatic antioxidants such as CAR, ASC and the activity of enzymatic antioxidants CAT, POX, APX, and SOD have been measured. Wheat plants exposed to lower concentrations of Hg (2.5 and 5 µM) did not experience any oxidative stress. However, treatment with 10 µM of Hg, the roots and leaves of wheat plants responded differently. Both the leaves and roots of plants treated with higher concentration of Hg (25 µM) were subjected to comparatively greater oxidative damage demonstrating that the antioxidant components were not able to remove the Hg stress at higher concentration in Triticum aestivum. ····· 10361101282
