Concept explainers
(a)
Interpretation: The validation of the given statement that carbohydrates linked to lipids are structural components of cell membranes has to be stated.
Concept introduction: Carbohydrates are one of the essential macronutrient in our diet. It is the major source of energy and is important for balanced diet.
Lipids are made up of hydrocarbons that are present in their most reduced form, which makes them a form of energy storage.
(b)
Interpretation: The validation of the given statement that carbohydrates cannot be stored in human body has to be stated.
Concept introduction: Carbohydrates are one of the essential macronutrients in our diet. It is the major source of energy and is important for balanced diet.
(c)
Interpretation: The validation of the given statement that the reactants for carbohydrate production by plants are carbondioxide and water has to be stated.
Concept introduction: Carbohydrates are one of the essential macronutrient in our diet. It is the major source of energy and is important for balanced diet.
(d)
Interpretation: The validation of the given statement that human dietary intake should always be less than 50 % carbohydrate by mass is to be stated.
Concept introduction: The major source of carbohydrates for plants and animals is via plant intake in diet. Carbohydrates are one of the essential macronutrient in our diet. It is the major source of energy and is important for a balanced diet.

- Use the literature Ka value of the acetic acid, and the data below to answer these questions. Note: You will not use the experimental titration graphs to answer the questions that follow. Group #1: Buffer pH = 4.35 Group #2: Buffer pH = 4.70 Group #3: Buffer pH = 5.00 Group #4: Buffer pH = 5.30 Use the Henderson-Hasselbalch equation, the buffer pH provided and the literature pKa value of acetic acid to perform the following: a) calculate the ratios of [acetate]/[acetic acid] for each of the 4 groups buffer solutions above. b) using the calculated ratios, which group solution will provide the best optimal buffer (Hint: what [acetate]/[acetic acid] ratio value is expected for an optimal buffer?) c) explain your choicearrow_forwardHow would you prepare 1 liter of a 50 mM Phosphate buffer at pH 7.5 beginning with K3PO4 and 1 M HCl or 1 M NaOH?
