The answer is C.Fructose is produced by hydrolysis of inulin
Make research to confirm my claims

C. They can be obtained by the hydrolysis of starch ❌❌❌

π™π˜Όπ™‡π™Žπ™€!! This one na correct answer (because question says β€œnot correct”).

Why? πŸ€·β€β™‚οΈ
βœ… Starch β†’ hydrolysis β†’ only gives 𝙂𝙑π™ͺπ™˜π™€π™¨π™š, not Fructose.
βœ… Fructose comes from hydrolyzing 𝙨π™ͺπ™˜π™§π™€π™¨π™š (cane sugar), 𝙣𝙀𝙩 π™¨π™©π™–π™§π™˜π™ πŸ‘€.

Take note ✍️ Both glucose and fructose are:

πŸ‘‰ Monosaccharides (simple sugars)

πŸ‘‰ Same molecular formula: C₆H₁₂O₆

πŸ‘‰ But π™™π™žπ™›π™›π™šπ™§π™šπ™£π™© structures (so they’re isomers!)

πŸ‘‰ Sweet, water-soluble, and can undergo fermentation

C. Can be obtained by hydrolysis of starch β€” NOT CORRECT ❌

So pick option C βœ…

monomeric unit of starch is the glucose molecule, which repeats in different arrangements to form amylose and amylopectin.

Fructose is not a monomer of starch.

Therefore, The correct answer is C

hydrolysis of starch gives maltose not even glucose
it is hydrolysis of maltose that gives glucose

The correct answer is:

B. reduce Fehling's solution

Glucose reduces Fehling's solution, whereas fructose does not. Fehling's solution is commonly used to test for the presence of reducing sugars, and glucose is a reducing sugar due to its ability to donate electrons and reduce other substances. Fructose, on the other hand, is a non-reducing sugar and does not react with Fehling's solution in the same way as glucose

During hydrolysis, enzymes break the long chains of amylose and Page 10 Chapter 1 4 amylopectin into shorter molecules. Depending on the enzyme's mode of action, the most common final products of starch hydrolysis can be maltodextrins, glucose, fructose or maltose.

so the answer should be B
