have limitations. The Coomassie dye only interacts with certain amino acids such as: arginine‚ histidine‚ lysine‚ tyrosine‚ tryptophan and phenylalanine. However‚ each amino acid has different structure from each other; therefore the Coomassie dye will interact differently with each amino acid. The Coomassie dye molecules are bound to proteins by elctronstatic attraction enhanced by hydrophobic bonding (Tal et al. 1984). Besides the interaction between Coomassie dye and amino acids‚ some compounds

greater polar molecule. Water is more polar than pentane and pentane is less of a polar molecule than methanol when it comes to comparing the mixture of water/pentane and the mixture of pentane/methanol. When food dye was added‚ it was able to form a homogeneous mixture of food because the food dye was a polar molecule‚ which made it water soluble. The next part of the lab was spent observing the effect chain length has on miscible alcohol in water. The result in table 4 matches the hypothesis that the

What will happen when you put a drop of water on wax paper? I think that it will just sit there and do nothing. First I put a drop of water on the paper Second I watched it to see what it will do Finally I wrote down that it just stayed still My hypothesis is correct What will happen when you move the water around with a toothpick? I think it will go flat and dissolve in the in the wax paper. First I picked up the toothpick Second I moved the water around with the toothpick Finally

the ability of bacteria cell wall to retaining the crystal violet dye or methylene blue. The cell walls for Gram positive microorganisms have a higher peptidoglycan and lower lipid content than gram negative bacteria. Bacteria cell walls are stained by the crystal violet. Iodine is then added as a mordant to form the crystal violet and iodine complex so that the dye cannot be removed easily. This step is usually called fixing the dye. However‚ the next treatment with a decolorizer‚ which is a mixed

This experiment involved exercising free-hand sectioning techniques‚ learning maceration procedures and application of staining techniques. Sudan dye for Lipids and IKI test for starch were applied on section stem‚ root and leaf parts of Tridax procumbens. Stem cross-section of T. procumbens showed distinct ground tissues and fourteen to sixteen vascular bundles organized into a ring. The root

as weddings‚ festivals or even births. Here‚ in the United States people often use it as tattoos. Since henna is not permanent‚ some get it to see how it will turn out before getting the actual tattoo. Another way to use henna is using it as a hair dye. It prevents breakage‚ it reduces dandruff‚ hair is thicker‚ it promotes growth because it has antibacterial and antifungal properties‚ and it also smooth’s the hair cuticle‚ giving hair healthy appearance. Henna is safe at any age and is mostly used

The Spectrophotometer Determination Of Protein Concentrations And The Effects Sodium Dodecyl Sulphate And Triton X-100 Have On Protein Concentration. INTRODUCTION Spectroscopy is used as a collective term for all the analytical techniques based on the interaction of light and matter. Spectrophotometry is one of the branches of spectroscopy where we measure the absorption of light by molecules that are in a gas or vapour state or dissolved molecules/ions (Tombs‚ et.al‚ 1959). Spectroscopy is the

national chemical engineering school in 1904. In 1909‚ this young chemist founded the company L’Oreal. He had an amazing “entrepreneurial spirit”. Schueller began by selling his own formulated hair dye to the Persian Hairdressers. The next year after that‚ he convinced Paris hair stylist to use his hair dyes for a fashion show‚ with his determination and ambition he succeeded and earned publicity. Another bit of information that we know is that Schueller had a passion for chemistry always trying new
