to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction? Your answer: Attempting to diffuse glucose and albumin through the 200 MWCO membrane resulted in only glucose passing through the membrane. The same concentration was used for both solutes‚ but albumin could not diffuse. The results contradicted my prediction because glucose was the only solute to diffuse through the 200 MWCO membrane. I predicted albumin would diffuse. 4. Put the

Experiment 2: Food Tests Objective * To study the presence of reducing sugars. * To study the presence of protein. Introduction In this experiment‚ glucose‚ maltose‚ lactose and sucrose are used for testing reducing and non-reducing sugars. Glucose is monosaccharide while maltose‚ lactose and sucrose are disaccharides of carbohydrates. Monosaccharaides are the monomers which make up all other carbohydrates and cannot be broken into smaller molecules by hydrolysis. Disaccharides are

and albumin through the 200 MWCO membrane. How well did the results compared with your predictions? Glucose could diffuse through the 200 MWCO while albumin could not diffuse through such membrane. It was because there was difference of molecule weight between them. Glucose (C6H12O6) has a molecular weight of 180 g/mol and albumin‚ which is protein with 607 amino acids‚ each single amino acid is 135 g/mole‚ has a molecular weight of(607 x 135) 81945 g/mole. Since the molecular of albumin is quite

solution turns to purple. The negative test result is that the solution remains dark blue. The goal of the lab is to test if there are proteins presented in water‚ glucose‚ starch‚ egg albumin‚ bread‚ milk‚ and peanuts (Biomolecule Lab). Materials and Methods In this experiment‚ some water‚ glucose‚ starch‚ egg albumin‚ bread‚ milk‚ peanuts‚ and Biuret reagent are used. One dropperful of each solution are added to the test tubes. The peanuts and the bread are placed on a piece of paper. The peanuts

Background of the experiment Pure proteins are not readily available for study or use. There are certain methods that should be done in order to obtain proteins from its sources. The objective of this experiment is to isolate casein from milk and albumin from egg and to identify and explain the principles behind the methods employed for protein extraction. Results and Discussion There are many possible sources where we could get proteins. It can be from plants‚ invertebrates and microorganisms.

Abstract This experiment aimed to study the effect of various denaturants on albumin and casein protein extracts through viscosity measurements. 5 mL samples of native and denatured protein solutions were prepared‚ using -mercaptoethanol‚ urea and SDS as denaturants for albumin‚ and NaOH‚ NaCL‚ HCL‚ -mercaptoethanol‚ urea and SDS for casein. 5 mL blank solutions for each denaturant used were also prepared. The viscosity of the solutions were determined using Ostwald viscometer. ________
