Fully updated and expanded-a solid foundation for understanding experimental enzymology. This practical, up-to-date survey is designed for a broad spectrum of biological and chemical scientists who are beginning to delve into modern enzymology. Enzymes, Second Edition explains the structural complexities of proteins and enzymes and the mechanisms by which enzymes perform their catalytic functions. The book provides illustrative examples from the contemporary literature to guide the reader through concepts and data analysis procedures. Clear, well-written descriptions simplify the complex mathematical treatment of enzyme kinetic data, and numerous citations at the end of each chapter enable the reader to access the primary literature and more in-depth treatments of specific topics. This Second Edition of Enzymes: A Practical Introduction to Structure, Mechanism, and Data Analysis features refined and expanded coverage of many concepts, while retaining the introductory nature of the book. Important new features include: A new chapter on protein-ligand binding equilibria Expanded coverage of chemical mechanisms in enzyme catalysis and experimental measurements of enzyme activity Updated and refined discussions of enzyme inhibitors and multiple substrate reactions Coverage of current practical applications to the study of enzymology Supplemented with appendices providing contact information for suppliers of reagents and equipment for enzyme studies, as well as a survey of useful Internet sites and computer software for enzymatic data analysis, Enzymes, Second Edition is the ultimate practical guide for scientists and students in biochemical, pharmaceutical, biotechnical, medicinal, and agricultural/food-related research.

This manual is more specific to medical students’ especially first professional of Biochemistry. This book contains a huge variety of experiments related to carbohydrate, lipid and protein identification. Other contents of the book are, making of solutions (percentage, molar, normal and dilution) and buffer preparation of required pH by using Henderson Hasselbach equation. For medical and biochemistry students, this book also contains critical VIVA and OSPE questions with well defined answers. This book is a complete package for first year MBBS biochemistry class.

Phosphorus (P) is growth limiting nutrient and deficient in most soils of the world. Research was conducted on five soil series of Pakistan differing in soil properties. Phosphorus adsorption isotherms were developed and fitted to Langmuir and Freundlich equations to describe P adsorption process. The study suggests that the oxides of iron and aluminum are the main adsorbent at low P concentration, normally applied in agricultural soils and soil CaCO3 play role at high P level. This book is recommended for soil science community working on P chemistry.

Cadmium is a highly toxic heavy metal for both plants and animals. The presence of cadmium in soil is of great concern regarding its entry into food chain. Wheat is a staple food in many parts of the world including Pakistan. It accumulates more Cd as compared to other cereal crops. A number of approaches are being used to minimize Cd accumulation in edible plant parts. Proper plant nutrition is one of the good strategies to minimize damaging effects of cadmium on plants and to decrease its accumulation in edible plant parts. A pot experiment was conducted on wheat in a soil contaminated with Cd @ 30 mg kg-1. Zinc was applied using two different application methods i.e., soil applications (Zn @ 15 & 30 mg kg-1) and foliar applications (0.3 & 0.6% ZnSO4 solution) compared to control (without Zn but Cd). Results indicated that foliar application of 0.3% ZnSO4 solution increased the activity of antioxidant enzymes (catalase, ascorbat peroxidase and guiacol peroxidase) and effectively decreased grain-Cd concentration. Zinc application through both the methods increased the shoot and grain Zn, P and K concentrations as compared to control.

Diabetes mellitus is probably the single most important metabolic disease and is widely recognized as one of the leading causes of death and disability in the different countries of the World. It affects every cell in the body and the essential biochemical processes that go on there. Even in normal individuals, significant weight gain results in carbohydrate intolerance, higher insulin levels and insulin insensitivity in the fat and muscle tissues. Weight loss can correct all of these abnormalities in many instances and significantly improves the metabolic disturbance of diabetes in most of cases. Diabetes is characterized by three well-known syndromes, polydipsia (excessive thirst), polyphagia (excessive hunger) and polyuria (excessive urination). Although different medicines are available for treatment of all kinds of diabetes including its complications, however, trend local medicines is increasing day by day due to its non or very less sides effects us well as due to low cost.

Faisalabad is known as a city of textile not only in Pakistan but also all over the world. Several textile processing units are in operation in the surroundings of the city, which are releasing a substantial amount of azo dyes into the wastewater streams in the surroundings of these textile units.The discharge of these contaminants is considered to be a potential threat to the environment because of their hazardous nature. Thus, this study was undertaken to isolate the bacteria possessing high potential to degrade azo dyes from the wastewater discharged by the textile units. A total of 150 bacterial strains were isolated from these wastewater samples using minimal salt medium spiked with Reactive Blue ZBLN azo dye. Results revealed that some bacterial strains were able to decolorize 8 different dyes almost within 6 hours. Thus, the isolated bacterial strains have the potential to remove a variety of dyes from the liquid culture, which could be used to develop a biotreatment strategy for cleanup of the industrial wastewater prior to their discharge into wastewater streams of the surrounding area.

Tomato mosaic virus (ToMV) is the most important and commonly associated with tomato crop and is distributed throughout Pakistan. To combat this problem, tomato lines/varieties screened against the tomato mosaic virus (ToMV), in relation to epidemiological factors and different plant extracts (A. indica, A. aspera and W. somnifera) were evaluated for their efficacy to manage the disease.The most effective plant extract was A indica at 1% concentration to reduce disease.

Rice (oryza sativa L) is a principal source of food for more than half of the world population, especially in South and Southeast Asia and Latin America. Elsewhere, it represents a high value commodity crop. Composting offers the most sensible and economic way to avoid wasting useful natural resources, which create environmental problems, and at the same time it produces a high quality and inexpensive soil amendment. Recycling of organic wastes involves the return of the essential elements to soils that are taken up by plants and find their way into animal, domestic and industrial products. This recycled organic waste may be good supplement of chemical fertilizer. The compost is widely used as soil amendment to improve soil structure. In Pakistan composting could be very useful because, the waste disposal problem is becoming serious day by day.

Nutrients release during co-composting of poultry litter and fast food wastes is a regular phenomenon, however, after certain time period the rate of release of nutrients is high which depends on environmental conditions like temperature and microbial population. For co-composting mixing the three parts of poultry litter with one part of fast food is the best composition to get maximum amount of micro and macro nutrients.

Objective structured clinical/practical examination (OSCE/OSPE) is a difficult aspect for the first year medical students. This book helps to solve the problems related to OSPE in Biochemistry.It is also deals with all viva questions with solution in biochemistry for the student of first year MBBS biochemistry.
