BEETROOT PIGMENTS - and membranes – These pigments are betalain pigments (not‚ as often thought‚ anthocyanins)‚ which they replace in some organisms. They are named after the Beet family of plants (Beta) but are also found in fungi (Fly Agaric - the red‚ spotted one!). In petals they presumably attract pollinating insects and may be present in seeds/fruits to encourage birds to eat them and so disperse the seeds. Man has selected for colour in beetroot‚ both because

Chromatography of Photosynthetic Pigments Abstract In this experiment a process of chromatography was used to separate chlorophyll a‚ chlorophyll b‚ xanthophyll‚ and beta carotene. When these pigments were obtained they were used to measure the wavelengths by way of spectrophotometer of each and the total of all the pigments wavelength. Introduction Photosynthesis is a process by which plants use the sunlight to convert it from light energy into chemical energy. This equation shows us how

The purpose of this paper is to help analyze or compare pigments from two organisms. Chromatogram is the pattern that the chromatography paper has created from its substances. A retention factor‚ also abbreviated as an Rf value‚ is the measurement of the distance that the sample had traveled. The formula for an Rf value is migration distance of solvent front divided by migration distance of substance. An Rf value is the distance the pigment travels from the original spot‚ which is the dot‚ of solvent

REPORT NAME :princess cucumber TOPIC : 3.8 & 8.2 : PHOTOSYNTHETIC PIGMENTS RESEARCH QUESTION INTRODUCTION The photosynthetic pigments are responsible for absorbing and trapping light energy the major pigments of photosynthesis are the chlorophylls. The two chlorophylls found in green plants are chlorophyll a and chlorophyll b. other pigments include carotenoids and phycobilins‚ sometimes referred to as accessory pigments. Carotenoids occur in all photosynthetic organisms‚ while phycobilins

The History of Paint Pigments Chem 111-404 April 24‚ 2013 Introduction: This report expresses five different pigments that were formed during chemical reactions. Three out of the total five reactions went through a metathesis‚ or double-replacment reaction. A metathesis reaction can be defined as “a chemical reaction in which an element or radical in one compound exchanges places with another element or radical in another compound.” (Webster). The other two pigments underwent a neutralization

INTRODUCTION: In atomic spectroscopy the samples are vaporized at 2000-8000k. The process of this involves two steps ‚ one is atomization of sample and the other is absorption of light radiation from light source. The atoms in the vapour are measured by absorption or emission at characteristic wave lengths. The main usage of this was to detect one element from another in the complex sample which has taken ie.‚ it has ability to perform multiple element analyses. Absorbance should obey Beer’s law

A removal process consisting of absorption‚ desorption‚ heat exchangers and auxiliary equipment is shown in Figure 10. Absorption is traditionally performed in a column with plates‚ random packing or structured packing. CO2 containing gas flows upwards and the absorption liquid flows downwards. The solvent (rich amine) is pumped further through a heat exchanger to a separation column. The absorbed CO2 is regenerated in a separation (stripper) column. Heat is added to the reboiler and a condenser
