Why does the colour leak out of beetroot? Procedure to investigate the effect of temperature Hypothesis- The higher the temperature while cooking the beetroot‚ the more pigments well leak out from the cell membrane‚ hence the absorbance would increase. My hypothesis was concluded by the facts that beetroot contains red pigments called betalians which are located in the cell vacuole. Normally the pigments cannot leak out; however cooking the beetroot allows the movement. This is because the cell

Carbohydrate: Ethanol from Sucrose Abstract The purpose of this lab was to demonstrate the fermentation process of ethanol from the substrate sucrose. To make ethanol from sucrose two enzymes invertase and zymase were used. Vacuum filtration and fractional distillation were performed to get a more concentrated solution. The density of ethanol was .825 g/mL with a percent composition of 85% pure ethanol. Introduction

source is ethanol (C2H5OH). It is an alcohol fuel manufactured by fermentation and distillation of crops that are high with starch and sugar‚ such as grains‚ sugarcane (most commonly used)‚ corn‚ and fruit. Other names for ethanol are ethyl alcohol‚ drinking alcohol‚ and grain alcohol. It can also be made from trees‚ grasses‚ woods‚ and plant waste. It is a colourless‚ flammable liquid that is categorized under bio-fuel. Brazil is the largest suppler and consumer of ethanol in the world. Ethanol functions

Why does colour leak out of cooked beetroot? Introduction When cooking a beetroot you are recommended not to remove the outer skin and not to cut off the entire stalk if you do not want the red dye in the cooking water. Beetroot contains a red pigment called betalain‚ which is in the cell vacuole. Normally the betalain stays inside the cell‚ however when the cell is exposed to extreme temperatures they leak out. The reason why they leak out is because of the cell membrane structure. When the

The aim of this thesis project is to study in vitro the permeability of amorphous drug systems in different conditions. First‚ three complementary techniques are performed to characterize the crystalline and amorphous form of indomethacin. These techniques include IR spectroscopy‚ Raman spectroscopy and differential scanning calorimetry. Indomethacin is a compound belonging to class II of the BCS and is consequently a poorly water-soluble drug. The limiting step in order to have a good bioavailability

included pollution and other harmful effects. People need to shift their views to the alternative energy resources such as ethanol‚ alcohol extracted from fruits. Food consumption should never be sacrificed‚ therefore‚ using fruit wastes is wiser. Santol is locally abundant fruit with popularly eaten pulps and normally thrown peelings. The study focuses on extracting ethanol from Santol peelings‚ using white and brown sugar‚ and comparing it to the commercial in flame propagation‚ duration‚ temperature

Brine shrimp and Ethanol research paper Ethanol is an alcohol substance that has effects on growth in organisms. Brine shrimp are used to tell the different levels of acidity in environments. Organisms absorb the substance around it; sometimes it has no effect on them sometimes it does. The best way to figure out if the environment has an acidity level too high for normal growth is to put the organism in a dish and watch carefully and observe any changes that occur in comparison to a normal organism
