Triacylglycerols, with their hydrocarbon-like fatty acids, have the highest energy content of the major nutrients.   (a) If 15% of the body mass of a 70.0 kg adult consists of triacylglycerols, what is the total available fuel reserve, in kilojoules and kilocalories, in the form of triacylglycerols? Recall that 1.00 kcal = 4.18 kJ.   (b) If the basal energy requirement is approximately 8,400 kJ/day (2,000 kcal/day), how long could this person survive if the oxidation of fatty acids stored as triacylglycerols were the only source of energy?   (c) What would be the weight loss in pounds per day under such starvation conditions (1 lb = 0.454 kg)?

Question

Triacylglycerols, with their hydrocarbon-like fatty acids, have the highest energy content of the major nutrients.

 

(a) If 15% of the body mass of a 70.0 kg adult consists of triacylglycerols, what is the total available fuel reserve, in kilojoules and kilocalories, in the form of triacylglycerols? Recall that 1.00 kcal = 4.18 kJ.

 

(b) If the basal energy requirement is approximately 8,400 kJ/day (2,000 kcal/day), how long could this person survive if the oxidation of fatty acids stored as triacylglycerols were the only source of energy?

 

(c) What would be the weight loss in pounds per day under such starvation conditions (1 lb = 0.454 kg)?
