and started adding one scoop of our enzyme catalyst‚ in this case‚ the yeast. We then proceeded to measure and add 1 mL of distilled water to test tubes A-D. To get a more accurate measure of 1 mL of distilled water‚ we used the dropper labeled “W” to drop distilled water into the 5 mL graduated cylinder until we saw that the bottom of the water line reached closely to 1 mL. Next‚ we took the four tubes with the scoop of yeast and added to each the corresponding 1 mL of water from tubes A-D. As

Leah Romero 04/18/2018 Lab 9 Conclusion Chem. 102L For lab 9‚ isolation of casein‚ the main purpose was to take the milk sample that was provided in the lab and through the addition of acid‚ be able to find the pH of the milk at the isoelectric point of casein. Isoelectric point is the pH at which a particular molecule carries no net electrical charge. The main points of the lab or the outcomes we were looking for were to be able to look at the properties of proteins in casein and be able to identify
