Contrary to legend, camels do not store water in their humps, which actually consist of large fat deposits. How can these fat deposits serve as a source of water? Calculate the amount of water (in liters) that a camel can produce from 1.0 kg of fat.Assume for simplicity that the fat consists entirely of tripalmitoylglycerol.

Respuesta :

Answer:

A) Oxidation of fats releases metabolic water

B) [tex]1.54[/tex] L of water per kg of tripalmitoylglycerol

Explanation:

A) During the oxidation of organic substances (fats) releases metabolic water along with release of energy

For example –  

 Oxidation of one mole of Palmitic acid (C16H32O7) acid releases 146 mole of H2O. In Tripalmitoylglycerol (fat C51H98O6) , there are 3 palmitic acid residues connected to glycerol molecule via ester bonds.

Oxidation of Palmitoyl CoA:

almitoyl-CoA + 23O2 + 108Pi + 108 ADP => 88nCoA + 108 ATP + 16CO2 + 23 H2O

B)

Molecular weight of tripalmitate [tex]= 807[/tex] g/mol

Number of moles in one Kg of fat  

[tex]= \frac{1000}{807}\\[/tex]

[tex]= 1.24[/tex] mole

Mass of water

[tex]1.24 * 69 * 18.02[/tex] ([tex]69[/tex] moles of water and weight of water [tex]= 18[/tex] grams)

[tex]= 1541.8[/tex] grams

Density of water [tex]= 1[/tex] g/mL

Volume of water [tex]= 1.541[/tex] L
