All Biomolecules have certain functions and these molecules all have a unique structure which is why they function in these ways. These molecules are known collectively as macromolecules‚ these molecules are grouped into four main categories which each have there own structure. These structures are the key to the macromolecules functions as each of them do a specific task in the body. Macromolecules are grouped into carbohydrates‚ nucleic acids‚ proteins‚ and lipids. In most cases macromolecules

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:

phosphates are easily broken down to release energy and are added in a covalent bond during processes like respiration. ATP is the source for driving active transport and reactions like cellular respiration and photosynthesis. ATP is broken down by hydrolysis. This results in adenosine diphosphate and an inorganic phosphate. Along with this comes the release of energy which can be used all through-out the system. Taking this step one further you can produce AMP‚ which contains only one phosphate group

Everybody is supposed to do all sorts of test to identify the bacteria. The first thing I did was smear my bacteria on a liquid medium. I then proceeded to incubate the medium for 24-48 hours. 1. GRAM STAIN The next step I took in finding my unknown bacteria was to gram stain it. This is used to differentiate

4-(hydroxymethyl)phenol the second is treating the 4-(hydroxymethyl)phenol compound with NaCN in hot DMF to form the product of 2-(4-hydroxyphenyl)acetonitrile. Then 2-(4-hydroxyphenyl)acetonitrile will be refluxed with H2O and Ethanol. After the hydrolysis with water and ethanol‚ this compound will be catalysed using a Pt catalyst which forms the product of acetamide then condensed with hot piperidine gives 2-[4-(2-oxiranylmethoxy)phenyl]acetamide. Then the oxirane ring of 2-[4-(2-oxiranylmethoxy)phenyl]acetamide
