Concept explainers
(a)
To determine: The total available fuel reserve in both kilojoules and kilocalories in the form of triacylglycerols if 15% of the body mass of 70 kg adult consists of triacylglycerols.
Introduction:
The most common form of lipid present in diet is a fat called triglycerides. Triglyceride or triacylglycerols is made up of three molecules of fatty acid and one glycerol molecule. The fat or triglycerides contains chemical energy which is released by the hydrolysis or breaking down of fats into fatty acid and glycerol molecules. Beta oxidation decomposes the fatty acid into two carbon atom molecule that helps in the release of energy.
(b)
To determine: The number of days a person could survive if the oxidation of fatty acids stored as triacylglycerols are the only source of energy.
Introduction:
The fat or triglycerides contains chemical energy which is released by the hydrolysis or breaking down of fats into fatty acid and glycerol molecules. Beta oxidation decomposes the fatty acid into two carbon atom molecule that helps in the release of energy.
(c)
To determine: The value of weight loss in pounds per day under starvation.
Introduction:
The fat or triglycerides contains chemical energy which is released by the hydrolysis or breaking down of fats into fatty acid and glycerol molecules. Beta oxidation decomposes the fatty acid into two carbon atom molecule that helps in the release of energy.
