The prevalent color of spring is of course green in a variety of shades. But‚ in addition‚ splashes of yellow‚ red‚ pink‚ and magenta are seen in the foliage of some plants. As time

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

this in mind‚ what organelle do you think would be the most numerous inside the cells of your mouth? (Hint: what organelle is responsible for breaking things down and digesting?) lysosomes What is the movement of the chloroplasts in the hydrilla leaf cells? what its direction? and what process could account for the movement of the cytoplasm? Clockwise movement. The lipotubuloids consisting of osmiophilic granules surrounded by a system of microtubules move from one place to another within a cell

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

5: Photosynthesis Problem: If the leaf disks are treated in a way you know increases the net rate of photosynthesis‚ should they start to float faster or slower? Why? Hypothesis: If the leaf disks were bathed in a red light source‚ then the rate of photosynthesis would increase than leaf disks that are bathed in a regular light source because chlorophyll absorbs red pigment and reflects green pigments. Therefore‚ shining a red light source onto the leaf disks would cause them to absorb more

Evidence: The process of photosynthesis requires sunlight for its nutrients to make their way into the chlorophyll on green plants. This suggests that without direct sunlight‚ photosynthesis will not be completed correctly or the plants functions will not work properly. Majority of plants that undergo photosynthesis have chlorophyll stored within them‚ it is what gives them their green color. However‚ there are few species of plants that don’t acquire chlorophyll‚ but still undergo the process of

focused on extracting and separating pigments of Chloroplast. For the procedure green leaves were grinded in a mortar with some chemicals and the fluid was filtrated to use for further analysis. Stripes of this solution were put on a filter paper and later‚ after dried placed into a beacon of solvent. After this the chloroplast pigments were separated by the solvent into groups of more or less soluble pigments. Aim How many pigment types are present in a green leaf? It is hoped to be able to identify

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
