Metabolic Water from Protein Oxidation
Metabolic water produced by oxidation of 1 gram of protein is:
- 1.07 g
- 0.60 g
- 0.56 g
- 0.40 g — Correct Answer
Explanation:
Correct Answer: 0.40 g
Oxidation of 1 gram of protein produces 0.40 g of metabolic water — the lowest among all major nutrients. This is because protein contains nitrogen, sulphur and other atoms that reduce the effective H:O ratio available for water formation.
Complete Metabolic Water Table
- Fat: 1.07 g (highest — camels store fat in humps)
- Glucose/Sugar: 0.60 g
- Starch: 0.56 g
- Protein: 0.40 g (lowest)
Significance
Metabolic water comprises 5–10% of total water intake of domestic animals. Animals adapted to desert environments (camels, kangaroo rats) maximise metabolic water by oxidising fat stores.
