carrier of chemical energy in all living organisms. It consists of adenine linked to D-ribose (i.e. adenosine); the D-ribose component bears three phosphate groups‚ linearly linked together by covalent bonds (see formula). These bonds can undergo hydrolysis to yield either a molecule of ADP (adenosine diphosphate) and inorganic phosphate or a molecule of AMP (adenosine monophosphate) and pyrophosphate. Both these reactions yield a large amount of energy (about 30.6 kJ mol–1) that is used to bring about

Carbohydrateby Anthrone Method Carbohydrates are the important components of storage and structural materials in the plants.They exist as free sugars and polysaccharides. The basic units of carbohydrates are themonosaccharides which cannot be split by hydrolysis into more simpler sugars. The carbohy-drate content can be measured by hydrolysing the polysaccharides into simple sugars by acidhydrolysis and estimating the resultant monosaccharides. PRINCIPLE Carbohydrates are first hydrolysed into simple

interaction (Astrand & Rodahl‚ 2003). The bound myosin head requires ATP in order to detach from actin. Once detached the myosin head hydrolyses ATP and the products adenosine diphosphate (ADP) and inorganic phosphate (Pi) remain in the myosin head. Hydrolysis of ATP initiates a change in the shape of the myosin head promoting myosin-actin interaction. Once rebound the myosin releases Pi‚ causing the head to swivel and drawing the actin in. At the end of its range the myosin head releases ADP and ATP

Photocatalytic degradation of methylene blue using TiO2 nanoparticles Nupur Mittal Chemical Engineering‚ IIT (BHU) Varanasi. Abstract: The aim of this research is to reduce the pollution caused by methylene blue dye in waste water coming from textile industries. For this purpose‚ TiO2 nanoparticles are made as they show good photocatalytic activity in degradation of dyes into harmless products. Synthesis is done using titanium butoxide and 2-propanol. The particles formed were a little larger

form disaccharides or polysaccharides. It can also join carbohydrates to non-carbohydrate molecules. A glycocidic bond is a condensation reaction which means when it is formed‚ water is a product. This also means that the bond needs water to break (Hydrolysis) which makes it quite strong. This kind of bond is called covalent.

RESEARCH PAPER ON BIOLOGICAL ACTIVITY OF ACTINOMYCETES ................ ABSTRACT: The microorganisms are ubiquitous in nature. They are found in probably every environmental condition present on earth. Actinomycetes were originally considered to be an intermediate group between bacteria and fungi but now are recognized as prokaryotic organisms with high G+C (>55%) content in their DNA. Our project aim is to evaluate some biological activities of Actinomycetes like:
