The energy stored in the bonds of any fat based molecule, or lipid, is greater than that of a carbohydrate molecule. Simple carbs are easily broken down for quick bursts of energy, while complex carbs take longer to break down. Fats on the other hand, are all more difficult to digest because of the size of their molecules and the complexity of their structure. Fats are also stored more rapidly; they are the body's emergancy power source.
Your body looks to simple carbs for energy first, then more complex carbs. It then gets energy from fat, and finally protein (the bodies of people suffering from anorexia or malnutrition will break down the muscles in order to get energy from proteins).
If two people were on a stranded island and could only eat either carbs or fats, and one dude ate all carbs and the other ate all fats, the guy eating all fats would have a way better chance at living longer, considering they were both in the same state of health, because fats are more complex organic carbon chains, and take longer to break down.
It's not. Carbs are much better. That's why marathon runners load up on pasta prior to the run.
A no carb diet switches your body from burning carbs that are in just about everything to fat. Look up low carb diets for further detail.
Fat is a organic energy reserve.
Fatty acids have significant van der Waal's force between them. (as a result they form triglycerides with relatively high melting points that are solids at room temperature)
Yes, gram for gram fat provides approximately twice as much energy as carbohydrates.
Fats have higher energy values than carbohydrates due to the different structures that both of them have. Fats burn and make more C-O bonds than carbohydrates.
Lipids contain less oxygen compared to carbohydrates and they hence have higher energy values.
Because oxidation is complete. Much energy is conserved.
When it comes to carbohydrates or fats producing more ATP, fats tend to produce more ATP per gram. Fats contain about 33 percent more ATP than carbs.
Yes, hydrogen sulfide
The carbohydrates are already ina more oxidized state than the triacylglycerols.
Fats actually contain a lot more energy than carbohydrates. The reason carbohydrates are used for energy before fats is because carbohydrates are easier to break down; reactions involving carbohydrates generally have a lower activation energy. This means that less energy is used to release the energy in the bonds of the carbohydrates than fats. In other words, although fats contain more energy, it is more efficient for the body to break down carbohydrates than fats. Once carbohydrate supplies diminish, fat stores can be broken down to use for energy, but doing so is not the body's favorite thing to do.
Fats are more reduced than carbohydrates, therefore there is more oxidation that occurs in the breakdown of fats, and hence, more energy is produced.
water energy
Fats provide a form of store energy. Fats can provide more than half the energy that the body needs and twice as much as than carbohydrates
Lipids store more energy per gram than carbohydrates or proteins.
They have more bonds, the more bonds a molecule has the more energy is released when the molecule is broken down, which is also why saturated fats have more energy than unsaturated fats or sugars
Japan.
No. Long chains of hydrocarbons, basically what lipids are, store much more energy in the bonds than carbohydrates do.
