Organization of pigments in photosystems. a) What is the concept of a photosystem? b) Photosystems are organized into two subcomponents: * antenna complex: Lots of pigments (A‚ B‚ and carotenoids) Pigments along with some proteins that organize some pigments about 200 found‚ scaffold proteins * reaction center complex A pair of chlorophyll A are found

far back as the 1300s. Food color additives are dyes‚ pigments or substances that impart color when applied to a food‚ drug‚ cosmetic‚ or the human body. The Food and Drug Administration (FDA) is responsible for regulating all color additives used in the United States. All color additives permitted for use in foods are classified as "exempt from certification" or "certifiable". Color additives that are exempt from certification include pigments that are derived from natural sources such as vegetables

wavelengths to experience the release of excess gases within a thirty-minute time period. The white light experienced the most success by concluding the thirty minutes with eight floating disks out of ten. The Activity of Photosynthetic Pigments Silica gel chromatography can be used to determine what light wavelengths are used for photosynthesis. In this experiment‚ chlorophyll a‚ chlorophyll b‚ carotene‚ and xanthophyll were tested. The distance moved by molecule and the distance moved by the solvent

Lesson Learning Outcomes Upon completion of this lecture‚ students should be able to: understand the structures and properties of amino acids know the groups of amino acid What are amino acids? Amino acids are molecules that when combined with each other proteins. Amino acids contain a central tetrahedral carbon atom (α-carbon) amine group‚ carboxyl group‚ R-side chain The R-side chain determines the different amino acids There are 20 common amino acids Amino acids can join via peptide

of Lycopene supplement. Lycopene was extracted from tomato wastes by using acetone and purified by column chromatography. The extract was characterized by UV-Vis spectrophotometer. An average recovery of 40 mg lycopene / kg tomato wastes was obtained. Lyco-cookies were prepared by using common ingredients containing 3 mg lycopene per serving. Introduction Lycopene is an open chain pigment of unsaturated carotenoid which is responsible for red colour found in tomatoes‚ grapes‚ watermelon‚ and

Gel filtration GEL FILTRATION OF PROTIENS Aim: The aim of this experiment is to identify proteins from a complex mixture using the gel filtration technique also known as size exclusion chromatography. This technique is widely used by biochemists when proteins larger than the pores are excluded from the column and the smaller molecules elute last and then collected in test tubes for examination by spectroscopic techniques. The red/brown proteins‚ in particular‚ will be observed closely
