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 : a. neither glucose nor albumin 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

In the scientific method‚ a chemical test that is sensitive to these groups can be used to identify molecules that are in that class. Testing involves many procedures that are very precise. This lab is broken down into five different sections; we will be using the Biuret Test for amino groups present in proteins. The Iodine Test to identify

Proteins are large biological molecules that are made up of one or more chains of amino acids. Proteins perform many different functions within a living organism‚ such as catalysing metabolic reactions‚ replicating DNA‚ responding to stimuli‚ and transporting molecules from one location from another. All proteins differ from each other primarily by their sequence of amino acids which is usually determined by a nucleotide sequence of their genes‚ resulting in a three-dimensional fold that determines

Then it travels down the esophagus into the stomach‚ where hydrochloric acid kills most contaminating microorganisms and begins mechanical break down of some food (e.g.‚ denaturation of protein)‚ and chemical alteration of some. The hydrochloric acid also has a low pH‚ which is great for enzymes. After some time (typically an hour or two in humans‚ 4–6 hours in dogs‚ somewhat shorter duration in house cats‚ ...)‚ the resulting thick
