In summary, the conversation discusses whether or not a person could break down and re-assemble elements in carbohydrates to create water in the body. It is mentioned that carbs are a good source of water and their breakdown can result in the formation of water. However, it is also questioned how this idea would work, as the person would need to consume the carbs. The conversation then shifts to a hypothetical scenario where a person is aboard a ship with limited water supply and must choose between high-carb or high-fat rations. It is suggested that a person on a high-carb diet may require less additional water to survive, but this is considered a strange idea.

Just wondering if someone was dehydrating whether the elements in carbohydrates (or anything else for that matter) could be broken down and re-assembled into water by the human body. I'm going to guess no, but it'd be interesting if we could...

Actually, carbs are a good source of water, and the breakdown of carbs does result in the formation of water (if I recall correctly). However, I'm not sure how your idea would work...the person would have to be consuming the carbs, wouldn't (s)he ?

if you were aboard ship with an inadequate supply of water for the trip
and two types of rations each supplying the same number of calories
should you eat the hi-carb rations
or the hi-fat rations

one of those clever biology people might actually know

a person living on hi-carb rations might require less additional water to survive. it is conceivable though a strange idea
 

Related to Can water be synthesised from carbohydrates by humans?

1. Can humans produce water from carbohydrates?

No, humans cannot produce water from carbohydrates. Water is a compound made up of two hydrogen atoms and one oxygen atom, while carbohydrates are made up of carbon, hydrogen, and oxygen atoms. While carbohydrates do contain hydrogen and oxygen, they are not in the correct ratio to form water.

2. Is it possible for humans to synthesise water from carbohydrates?

No, it is not possible for humans to synthesise water from carbohydrates. The process of synthesising water, also known as hydration synthesis, requires a specific set of chemical reactions that can only occur in a laboratory setting.

3. Can humans obtain water from consuming carbohydrates?

Yes, humans can obtain water from consuming carbohydrates, but not directly from the carbohydrates themselves. When we consume carbohydrates, our bodies break them down into smaller molecules, including glucose. Glucose is then used in a series of chemical reactions to produce energy, and water is a byproduct of this process.

4. Is water a byproduct of carbohydrate metabolism?

Yes, water is a byproduct of carbohydrate metabolism. When carbohydrates are broken down in our bodies, water is produced as a byproduct. This process is called cellular respiration, and it is essential for providing energy to our cells.

5. How much water is produced from metabolising carbohydrates?

The amount of water produced from metabolising carbohydrates depends on the specific type of carbohydrate and the amount consumed. On average, for every gram of carbohydrates metabolised, about 0.5 grams of water is produced. However, this can vary based on individual factors such as metabolism and activity level.
