You do not give anything to compare the maltose to, but I assume you mean 'longer than glucose'.
Glucose is a monosaccharide, that is it consists of a single ring of carbon and oxygen atoms. Maltose is a disaccharide, that is two glucose rings joined together. That makes it almost twice as big as glucose. If the particles of the two sugars are at the same temperature, they have the same average kinetic energy, so the more massive ones move more slowly. The slower movement means maltose diffuses more slowly out of the tubing.
What else can I help you with?
What will and won't pass through a visking tube?
Cannot pass through visking tubing: sugar starch lactose sucrose Can pass through visking tubing: Iodine Glucose Maltose
What is a type of tube that is semi-permeable?
visking tubing
What part of the human body acts a the visking tubing?
capillaries in the villi
Can salt pass through visking tubing?
No, salt molecules are too large to pass through the pores of Visking tubing, which is a semi-permeable membrane. Only smaller molecules like water can pass through the tubing via osmosis.
Why it was important to wash the outside of the visking tubing?
Washing the outside of the visking tubing helps remove any contaminants or bacteria that could potentially contaminate the contents inside the tubing. This step is crucial to ensure that only the intended molecules can diffuse in or out of the tubing without interference.
Can starch pass through visking tubing?
We supply Visking tubing and offer the following information: The molecular weight cut-off of this product is 12000 - 14000 daltons. This means in theory that molecules larger in MW than this will not pass through the membranes and ones smaller will. Starch has a very high molecular weight and the tubing is often used to illustrate the effect of enzymes breaking starch down into to simple sugars. Starch therefore should not pass through the membrane wall. The user of this product should be aware that this is a nominal cut-off and long thin molecules above the 14kd cut-off may go through and globular molecules below may be retained. In addition the charge on a molecule may effect the rate of transfer across the membrane.
Starch before it enters the Visking tubing?
Starch must be broken down into smaller molecules like glucose before it can enter the Visking tubing, as the tubing only allows smaller molecules to pass through its semi-permeable membrane. This breakdown of starch into glucose is typically achieved through the process of digestion, either by enzymes in the body or by external sources such as amylase. Once the starch is broken down into smaller molecules, it can pass through the Visking tubing via osmosis or diffusion.
Why could glucose could pass through the visking tubing?
Because it has starch in it.
What can you use as alternative to visking tube?
the visking tubing is useless and we need an alternative. can u helpful human beings help please? we are in the middle of a chaotic crisis trying to find the reason for osmosis. please help you kind human beings :) i hate you bye -from the scientists of Mars :
What is visking tubing?
Visking tubing is a type of semi-permeable membrane tubing used in dialysis and other separation techniques. It is made from cellulose or other synthetic materials and is used to separate molecules based on their size and charge. The tubing allows small molecules to pass through while retaining larger molecules, making it useful for purification and concentration of biological samples.
Why must rinse the outside of the Visking tubing thoroughly with water?
so as to prevent contamination. that should be one point.
What part of our body acts like the visking tubing?
The kidneys act like a visking tubing in our body. They filter blood and selectively reabsorb substances to maintain the body's balance of electrolytes and fluid volume. This process helps remove waste products from the blood while retaining important nutrients.
