The objective of this macromolecules lab was to identify the presence any of the major macromolecules in various every day food items. The three macromolecules that this lab was carried out for were carbohydrates‚ lipids‚ and proteins. There were five different experiments conducted and each of those experiments had one factor in common‚ they all had the same controls. The controls in this lab activity were already set for the lab activity. The controls were the distilled water and the baking soda

Ni-NTA agarose beads - reuse of Ni-NTA agarose beads for His protein (Jan/12/2005 ) Can someone guide me on how to get rid of imidazole adsorbed to Ni-NTA agarose beads so they might be reused. Thanks in advance. -mdsr- You will find lots of informations about NiNTA purification system. And a protocol for Ni-NTA regeneration... You can wash your resin with 0.5N NaOH 30min for rapid regeneration. And use the same resin for the same protein purification... For information : Handling : Ni-NTA

I think that this will happen because generally hydrochloric acid causes more damage to things and also it produces more aggressive reactions causing greater effects this I think means that the acid is more likely to effect or disable the proteins in the lipid bi-layer this means that if this happens the membranes selective permeability will be lessened and the restriction of the flow of pigment out of the beetroot will also be lessened so more pigment can and will flow out. I think

For the web site version of this report‚ tables are provided but diagrams are not. Executive Summary As the world’s population grows‚ the National Research Counc1il estimates that the supply of food required to adequately meet human nutritional needs over the next 40 years will be equal to the amount of food previously produced throughout the entire history of humankind. To meet this demand‚ animal scientists must develop new technologies to increase productive efficiency (that is‚ the yield

things. Chapter three is all about how molecule machines operate a cell. According to the book‚ these molecules are mostly made up of proteins and proteins carry out chemical reactions. They are very multitalented but they typically have one use or at most a very little. Each cell has thousands and thousands of proteins; there can be from 50 to 1‚000 proteins in a single chain. These chains come in various lengths and every link has very different properties. Some may have a positive charge and
