Summary Introduction
To review:
The molecular weight of fructose.
Introduction:
Fructose is a structural isomer of glucose and both have the same molecular formula but different structure due to isomerization. Glucose is a six-carbon ring whereas fructose is a five-carbon ring. Glucose has an

- In the formula for sucrose (structure shown above), the bottom ring is pyranose. True or False?arrow_forwardIdentify the name of each of the structures of sugar and identify as reducing or nonreducing sugar. One of the structures may be not identified from the usual structures of disaccharides. Kindly answer a, b, c, and d.You only identify the name of each structure of sugars and identify as reducing or nonreducing sugar. No explanation needed.arrow_forwardIn the 1970s, a process was developed thatconverts the glucose in corn syrup to its sweeter-tasting isomer, fructose.High-fructose corn syrup, a common ingredient in soft drinks and processedfood, is a mixture of glucose and fructose. What type of isomers are glucoseand fructose?arrow_forward

- Identify the component monosaccharides of each of the following compounds and describe the type of glycosidic linkage in each.arrow_forwardwhat is the difference between the structure of cellulose and the structure of amylose?arrow_forwardThe hydrolysis of the disaccharide sucrose results in the formation of the monosaccharides glucose and fructose, and the AG of this reaction is -29.3 kJ/mol. Sucrase is an enzyme that is able to catalyze the hydrolysis of sucrose. Which of the following statement(s) correctly describes what would happen if you added the enzyme sucrase to a solution of sucrose? All of the other three statements are correct. The activation energy of the reaction would increase. The AG of the reaction would become more negative (i.e., a larger negative number). The rate of sucrose hydrolysis would increase.arrow_forward
- The average fuel value of fats is 9kcal / g . A 1 oz French fries typically contains 4.5 g of fat. What is the fuel value in kcal) of a medium size French fries from McDonalds ( about 115 g)? Assume that fat is the only fuel source . (1oz = 454g) Use dimensional /unit analysis to solve this problem.arrow_forwardOlestra has been used in certain snack foods as an alternative to fats and oils. Its structure consists of a sucrose molecule in which all free hydroxyl groups have formed esters with oleic acid (an 18-carbon monounsaturated fatty acid). Olestra molecules have no caloric value because they are exceptionally large and cannot be digested. Draw the structure of olestra. Use R-COOH as an abbreviation for oleic acid.arrow_forwardDraw the Haworth structure of the tetrasaccharide:arrow_forward
