List one positive test and indicate the positive results for this sugar. And list one negative test and indicate the negative results for this sugar in order. Starch, maltose, sucrose, fructose, glucose, and xylose.

Question

Accepted Answer

∻Answer∻ ⚹ Benedict's test is positive for xylose, indicating the presence of reducing sugars. Iodine test is negative for xylose, showing no starch present. ⚹ ∻Solution∻ ‖ a ⋮ Positive test for xylose: Benedict's test is used to detect the presence of reducing sugars. When Benedict's reagent is added to xylose and heated, a color change from blue to green, yellow, orange, or red indicates a positive result. ‖ ‖ b ⋮ Negative test for xylose: Iodine test is used to detect the presence of starch. When iodine is added to xylose, there should be no color change, indicating a negative result for starch. The expected color would remain yellowish or brownish, as opposed to the blue-black color indicating the presence of starch. ‖ ∻Key Concept∻ ⚹ Benedict's test and Iodine test are used to detect reducing sugars and starch, respectively. ⚹ ∻Explanation∻ ⚹ Benedict's test causes a color change in the presence of reducing sugars, while the Iodine test changes color in the presence of starch. Xylose, being a reducing sugar, gives a positive result with Benedict's test and a negative result with the Iodine test. ⚹◊What specific test can be conducted to test for xylose and what are the positive and negative results for this sugar in comparison to other sugars like starch, maltose, sucrose, fructose, and glucose?⍭ Generate me a similar question◊
