Discussion for the research paradigm Input: Having the information that collagen was abundant protein in vertebrates people are used to extract collagen from mammals. But due to negative effects of collagen from mammals‚ fish skin serves as another option because it also contains collagen. It is much safer for it’s being said that marine collagen are not associated with the risk of bovine spongiform encephalopathy (BSE) outbreaks which is common in pig‚ cow or any mammals’ skins and bones.

ingredients like fat and sugar. Likewise the liquid ingredients should be balanced with the dry ingredients. The formation of the starch-protein matrix is important for the support and strength of the cake crumb. When these two ingredients are varied it affects the matrix. The varying sugar concentration will affect the extent of starch gelatinization and denaturation of protein. The addition of increasing levels of sugar in a recipe inhibits these phenomena and thus the matrix is weaker. The weakening of

Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction? Your answer: glucose diffused through the 200 MWCO membrane‚ while there was no diffusion of albumin. I predicted correctly. 4. Put the following in order from smallest to largest molecular weight: glucose‚ sodium chloride‚ albumin‚ and urea. Your answer: sodium chloride‚ urea‚ glucose‚ albumin.

that glucose is a monosaccharide‚ albumin is a protein with 607 amino acids‚ and the average molecular weight of a single amino acid is 135 g/mole. Which of the following will be able to diffuse through the 200 MWCO membrane? Your answer : c. glucose only Stop & Think Questions: The reason sodium chloride didn ’t diffuse left to right is that You correctly answered: c. the membrane pore size was too small. Glucose is a six-carbon sugar. Albumin is a protein with 607 amino acids. The average

07 and is to great to pass through the 20MWCO membrane. • Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction? My prediction was correct in this experiment. Knowing that glucose is a monosaccharide‚ it is of size to diffuse through a 200MWCO membrane. Albumin being a protein is dense with 607 amino acids and an average molecular weight of 135g/mole is not going to diffuse through the 200MWCO membrane

in cases of hypothermia and fevers). Usually‚ when such situations do appear‚ proteins/enzymes undergo a process called denaturation. When an enzyme experiences denaturation‚ it loses its structure. With the loss of structure‚ the enzyme ultimately loses its function as the substrate can no longer “fit” in the binding site. Of course‚ denaturation can only occur when an external factor is applied. In this lab experiment‚ this external factor is temperature/heat

carbohydrates‚ lipids‚ proteins‚ and nucleic acids. These are monomers and they link together into long chains that form polymers. Different reagents can be used to find the presence of these macromolecules. Proteins are made of carbon‚ hydrogen‚ oxygen‚ nitrogen‚ and sometimes sulfur. Proteins are covalently bonded in chains as polymers of amino acids. These bonds are called peptide bonds. Amino acids linked together form a polypeptide called a protein. Some proteins are also enzymes. The

The methyl group may be attached to a carbon or to a different atom. • Macromolecule: a giant molecule formed by the joining of smaller molecules‚ usually by a dehydration reaction. Polysaccharides‚ proteins‚ and nucleic acids are macromolecules. • Polymer: a long molecule consisting of many similar or identical monomers linked together by covalent bonds. • Monomer: the subunit that serves as the building block of a polymer. • Condensation (dehydration)

purpose of this lab was to look for different solutes that can cross an artificial membrane and to observe the effect of different concentrations of sucrose on the mass of a potato cell. Results for Part One suggested that the molecular weight of albumin and starch was too large to pass through the dialysis tube‚ but glucose and sodium sulfate molecules were small enough to pass through the dialysis tube. Also‚ a decrease in water weight occurred due the dialysis tube being placed in a hypertonic
