aldehyde groups of simple carbohydrates will react with phenylhydrazine but instead of yielding typical phenylhydrazones they make what is termed osazones where the OH group immediately adjacent to the keto group is oxidized to a keto group and it too adds phenylhydrazine to form the yellow to pale orange osazones that have definite melting points. So assignment of presumptive identity can be done my taking the melting point of a PURIFIED osazone from a purified carbohydrate. | yellow to pale orange

Although a diet free of carbohydrates is appropriate for individuals who are not exercising or only performing the low-intensity aerobic exercise‚ it is not appropriate for those individuals involved in the high-intensity exercise. In addition to the standard ketogenic diet‚ two modified ketogenic diets are discussed which integrate carbohydrates while maintaining ketosis. The first of these is the targeted ketogenic diet‚ which includes the consumption of carbohydrates around exercise. The second

Testing for the Presence of Lipids‚ Proteins‚ and Carbohydrates in McDonald’s Menu Items Emma Heironimus‚ White 3 There are four main macromolecules; proteins‚ nucleic acids‚ lipids‚ and carbohydrates. The presence of some of these‚ such as sugar‚ fat‚ starch‚ and protein‚ can be determined using tests such as Benedict’s solution‚ Lugol’s iodine solution‚ Biuret’s reagent‚ and Sudan III. Control tests were performed to determine what a positive result would appear like. Then the tests were performed

The sugarcane undergoing fermentation produced a volume of carbon dioxide that was nearly nine times more than the corn‚ wheat grain and wheat stalk. Wheat grain and corn was nearly doubled that of the wheat stalk and the control (Figure 1). Sugarcane was the leading plant material producing the highest volume of carbon dioxide (mean= 19.9 ± 0.996 mL) while other than the control; the wheat stalk produced the lowest volume of carbon dioxide (mean= 1.33 ± 0.036 mL). As time elapsed‚ the sugarcane
