Abstract In this experiment paper chromatography was used in order to identify two unknown amino acids using eight known amino ones. The two unknown ones were identified by comparing the distance they travelled up the chromatography paper and their Rf values to the corresponding values of the other eight known amino acids. The unknown amino acids identified were Glycine and Methionine. Introduction Proteins in cells are important in many ways. There are different types of proteins such as

EXTRACTION OF INVERTASE FROM YEAST AND EFFECT OF pH ON ENZYMATIC ACTIVITY Jenelle C. Faustino‚ John Gambit B. Garcia‚ Fatima S. Jusay‚ Oliver Alexander B. Lao and Eunice L. Licudine Group 4 2 E Medical Technology Biochemistry Laboratory ABSTRACT Enzymes are substances that are produced by living organisms and act as catalysts in order to speed up or chance a chemical reaction without changing itself at the end of the reaction. Invertase was extracted first from baker’s yeast. Determination

Julie Smith 2/14/2017 Bio 220 Lab Report Learning How to Use the Compound Light Microscope Introduction: Microscope is an instrument used to grow pictures of little questions that are difficult to see with the unaided eye. The compound light magnifying instrument‚ which will be utilized as a part of this lab movement‚ is an instrument with two focal points and different handles to center the picture. In this lab‚ we will learn about the proper use and handling of the microscope. Objectives:

2.3.3 Feature Extraction Feature extraction deals with the extraction of the distinctive features out of face images so that those face images can be differentiated among each other. There are several algorithms available for extracting features out of a face image. The most common is the use of mathematical formulas that generate a mathematical representation of a face image that is termed as a template‚ these templates are “the refined‚ processed and stored representation of the distinguishing

NUCLEIC ACIDS I.BASIC CONCEPTS II.CLASSES III.CHEMICAL NATURE IV.FUNCTION I.BASIC CONCEPTS NUCLEIC ACIDS polymeric macromolecules‚ or large biological molecules‚ essential for all known forms of life are made from monomers known as nucleotides Each nucleotide has three components: a 5-carbon sugar‚ a phosphate group‚ and a nitrogenous base If the sugar is deoxyribose‚ the polymer is DNA. If the sugar is ribose‚ the polymer is RNA. Together with proteins‚ nucleic acids are the most

put this in place the doctrine of separation of powers is put in action in the different parts of the nation. in this essay I will simply define the key terms which are separation of powers and then proceed by elaborating how how this separation of powers is important in running a state and how it came to be practiced in Botswana. I will then continue with a little critsism on this separation of powers and sum up with a well summarized conclusion. SEPARATION OF POWERS According to a French philosopher

As we know‚ the TLC is a separation technique that has two phases: the stationary phase and mobile phase. The stationary phase is silica gel (SiO2) which is very polar compound‚ while the mobile phase is 0.5% acetic acid which has less polar. Also‚ as we know‚ the compound will rather to stay with stationary phase or travel with mobile phase depend on its polarity. The result show as that the polarity of the solvent is the key factor for the compound to travel with it or stay in stationary phase

Chemistry Research Paper What is an anti acid? According to Cindy Quarters (2010)‚ “Antacids are medicines that are taken orally to help relieve sour stomach‚ heartburn‚ or acid indigestion”. This medicine is available without prescription but it is needed to take the correct dose. The different types of anti acids include calcium carbonate‚ sodium bicarbonate‚ magnesium hydroxide‚ aluminum hydroxide‚ and dihydroxyaluminum sodium carbonate. The cost of the anti acid will depend on how effective it is‚

Separation of Mixtures Mixtures exist in many forms in the world‚ and if it were not for methods of separation‚ many of these substances would be meaningless to us. Separating mixtures is extremely important to human lives; for example‚ many people filter water so that it is safe for drinking. Mixtures contain two or more substances that are not in a fixed ratio‚ and while some mixtures‚ such as concrete‚ are useful‚ others including salt water‚ are not as useful to us. Filtration‚ distillation
