E5 & E6 Extraction of Chlorophyll from Fresh Spinach and Investigation of the Photochemistry of Chlorophyll Chlorophyll a Chlorophyll b E5 - Extraction of Chlorophyll from Fresh Spinach E6 - Investigation of the Photochemistry of Chlorophyll The aim of this experiment is to investigate the photochemistry of chlorophyll. This experiment will be performed in two lab periods. In the first lab period you will extract chlorophyll‚ the green pigment in leaves‚ from spinach.

around graphite was discovered in Germany‚ and the modern pencil began to take form. In 1779‚ scientists determined that the material they had previously thought was lead was actually a form of microcrystalline carbon that they named graphite (from the Greek "graphein" meaning "to write"). Graphite is one of the three natural forms of pure carbon—the others are coal and diamond. In the late eighteenth century the Borrowdale mine was depleted‚ and‚ as graphite was now less plentiful‚ other

EXTRACTION OF TRIMYRISTIN FROM NUTMEG: Paul I. PURPOSE: The purpose of this experiment was to illustrate the extraction of a solid natural product from its natural source by partition with the aid of an organic solvent. Extraction is the process by which a compound or mixtures of‚ is transferred by separation from one phase into another. In this case‚ the major triglyceride contains a single fatty acid identified as myristic acid. It is a substituent

Strawberry DNA lab Extraction Purpose: The purpose of this lab experiment is to see if this particular type of fruit which in this case is a strawberry contains DNA. Using materials such as a Ziploc bag to help keep the entire strawberry in one place while it gets smashed and test tube to help better see the DNA and break down of the liquid in the left over strawberry sediments. Background information: The long thick fibers of DNA store the information for the function of the chemistry

WHEAT Wheat from which flour is made‚ is the most essential grain used in bread making because it is the only cereal that contains the proper combination of glutenin and gliadin. When two proteins glutenin and gliadin‚ are mixed with water will formed a gluten. Gluten is both plastic and elastic. It can stretch and expand without easily breaking. Wheat special properties allow bakers to produce an astonishing array of product‚ from pastry to cakes and cookies. Not only wheat is used for baking

Extraction of DNA from Calf or Hog Thymus/Isolation of Yeast RNA I. Abstract Nucleic acids may be divided into two groups RNA and DNA. DNA contains almost all the genetic information while RNA serves as the bridge between the DNA and proteins. Study of both DNA and RNA initially involves proper extraction/isolation. The storehouse of eukaryotic DNA is the nucleus (and in the mitochondria)‚ so experimentally‚ DNA is extracted from tissues that have a high nuclear to cytoplasmic mass ratio‚ such

Banana Oil Lab Report Jesse Bradford 7/10/14 MTWR Section Introduction In the banana oil lab we began with isopentyl alcohol + acetic acid isopentyl acetate + Water. We needed for this experiment a hot plate‚ clamps‚ pipette‚ 5mL vial‚ caps‚ hoses and a thermometer. Upon starting‚ our group set up an open system experiment that allowed gases to be released to avoid pressure build up. We mixed together to molecules‚ 1.0mL of isopentyl alcohol‚ 1.5mL of acetic acid

Biology 110 March 2‚ 2015 DNA Lab BACKGROUND In this laboratory experiment‚ students were introduced to DNA electrophoresis. DNA electrophoresis is an instrument that many forensic scientists use to get a DNA fingerprint as an evidence for crimes. Not only can it be used for forensic science‚ people can use this for paternity test‚ as well as look for evolutionary relationships among organisms. Agarose is used to make the gel that the DNA fragments are going into. Since DNA particles are negatively
