WHAT IS PHARMACOGNOSY? Pharmacognosy is the study of drugs of natural origin. The term comes from two Greek words: "pharmakon" meaning drug or medicine‚ and "gnosis" meaning knowledge. The American Society of Pharmacognosy defines pharmacognosy as "the study of the physical‚ chemical‚ biochemical and biological properties of drugs‚ drug substances or potential drugs or drug substances of natural origin as well as the search for new drugs from natural sources". Plant preparations are said

Protein Essay- Erin Keegan What are proteins? A polypeptide is a chain of monomers joined up to make a polymer. Proteins are organic polypeptides made up of a chain of amino acid residues- they’re residues because they lose a water molecule. The amino acids (monomers) join up by forming peptide bonds. When two amino acids join together‚ they become a dipeptide. This happens when the carboxyl group of an amino acid and the amino group of another amino acid link up through a condensation reaction (which

would also serve as a public advertisement for the program‚ bringing the act of reading‚ a process often hidden and done in private‚ to the forefront so that it leaves a behavioral residue for other students to imitate. Berger states that the use of a marker which makes a product more public can contribute to public “residue” that lingers and promotes ongoing social transmission. This effect combined with immediate social transmission resulting from the leaderboard and prizes can allow the program to

In the second separation of this experiment‚ the Erlenmeyer flask with the first filtrate was put into a beaker so the filtrate was in the beaker. The beaker was then heated on a hotplate until near boiling. After the whey protein had precipitated‚ a vacuum filter was used to filter out the whey. These proteins were then air-dried. A qualitative test was done to indicate that the sample extracted was the protein whey. Again‚ a small test tube was used and 2 mL of protein test solution was put in

fires where solid fuels are burning or when vegetation comes into contact with lava in volcanic eruptions. In general‚ pyrolysis of organic substances produces gas and liquid products and leaves a solid residue richer in carbon content‚ char. Extreme pyrolysis‚ which leaves mostly carbon as the residue‚ is called carbonization. The process is used heavily in the chemical industry‚ for example‚ to produce charcoal‚ activated carbon‚ methanol‚ and other chemicals from wood‚ to convert ethylene dichloride into vinyl

The Expression and Purification of Recombinant Green Fluorescent Protein (rGFP) From E. coli strain‚ BL21(DE3)‚ Using Ni2+-Agarose Affinity Chromatography Abstract: The purpose of these series of experiments was to express and purify recombinant Green Fluorescent Protein (rGFP) from the E. coli strain‚ BL21(DE3) by beginning with its purification via a Ni2+-agarose affinity chromatography column. The His6 tag of the rGFP bound to the Ni2+-agarose column and washes and elutions were obtained

Neil’s (played by Robert Shaun Leonard) demise was in absolutely no possible way a random occurrence in the movie "Dead Poets Society" or in short DPA. Neil’s death can in fact be compared to a conclusion in a science experiment that was already clearly stated in the hypothesis. A very high quantity of events and symbolism was used in the early structural stages of the movie to give the viewer an obvious impression that he would live to see out the completion of the movie. The scene of Neil’s death

shows how bauxite mining affects environment in Jamaica. After the mining process takes place‚ the residual red mud is dumped into a lake in the highlands of Central Jamaica. However‚ these "red mud lakes" resulted in the percolation of caustic residues (sodium) into the underground aquifers in local areas. The sludge contains high levels of heavy metals and other pollutants. Thus‚ the soil remaining‚ cannot sustain life on it. The environmental impact of Jamaica’s bauxite mining symbolizes

survival and long-term prosperity largely depend on new investment that MMI can hardly see coming from its own revenues. A chemical known as ASTOGO is used to clean the micro chips. The cleaning residues become highly toxic‚ particularly to birds‚ fish and other marine life. Proper disposal of the toxic residues requires that they be shipped to the only two licensed disposal sites: one in Western Canada and one in the southern United States. The disposal of the toxic waste is costly and requires transporting
