    Introduction The natural source of both plasma and electromagnetic radiation (EMR) is the sun. There are various similarities such as the presence of electric and magnetic field in both EMR and plasma. Both transport contain energy and are ubiquitous in the universe. However‚ there are large differences between EMR and plasma. Differences between EMR and plasma EMR is energy that propagates through a medium in the form of EM waves. It has an electric and magnetic field which oscillate in

    where the protein was fully denatured. Then‚ the curve dropped quickly. With the raising of the temperature‚ protein in the solution got denatured. When the temperature increased from 60℃ to 80℃‚ the structure of protein got unfold. When the solution was heated‚ the H-bond was broken. The hydrophobic parts of protein were inside the protein surrounded by hydrophilic parts before unfolding. With the temperature increasing‚ the hydrophobic parts were exposed. The hydrophobic parts of proteins interacted

    Michael Murray English 101 Theresa Stein Across the Water “There’s a large posterior fossa mass. Surgery is scheduled for two o’clock.” Those words launched a journey of nearly ten years for me and my youngest child. A journey largely responsible for shaping the people we’ve become since that horrendous‚ God-awful moment. “That’s only an hour from now… I need more time and I need more information‚” I finally responded. It felt as though I’d been slammed between two steel plates and pushed

    Lab 3 – Homework 1. Purpose of today’s experiment: To determine the effect osmotic pressure might have on cellular membranes‚ specifically when beet slices are placed in NaCl solutions of varying concentrations. 2. Hypothesis: The osmolarity will directly increase with increasing NaCl concentrations. 3. Control = Distilled Water – this was present in all solutions 4. The independent variable – salinity of the 6 solutions; while predetermined‚ the NaCl concentrations varied from 0% to 15%.

    Effect of Temperature on Beetroot Membranes _Aim_ This practical will test the effect of temperature on the integrity of the membranes‚ _Introduction_ The cells of beetroot contain a pigment called betalain in their vacuoles. It is kept inside the cells by the membranes. If these membranes are damaged‚ then the betalain leaks out. The amount that leaks out can be assessed‚ as the leaked out pigment will color the water surrounding the cells. This information can be used to find out how temperature

    EXERCISE 3: DIFFERENTIAL PROTEIN PRECIPITATION Vanessa Andrea Estepa University of Mindanao‚ College of Science and Mathematics ABSTRACT: Denaturation is the disruption in the original conformation of the protein wherein the secondary‚ tertiary and quaternary structures are all affected. Denaturation is brought about by various kinds of physical and chemical means; this includes the addition of strong acids‚ heavy metal cations‚ alkaloidal reagents‚ salting out and addition of organic solvents.

The more diluted the solution was‚ the less blue it was. The R2 value of the standard curve of BSA dilution was obtained to be 0.9972‚ which is close to 1. The closer to 1 the R2 value was‚ the more accurate the linear portion was. The error percentage of each unknown was large: 25.9% for skim milk‚ 95% for soy sauce‚ and 64.7% for egg white. The vast

    Estimation of protein concentration Introduction Protein assays are designed to measure the total protein in a solution. Protein assays are quantitative if the protein to be assayed is available in sufficient quantity such that one is able to use it to create a standard curve. If this cannot be achieved‚ then a standard protein‚ such as albumin‚ may be used for a standard curve with the understanding that the results on the unknown protein are semi-quantitative. Since most proteins are not available
