the difference between protein, carbohydrates and sugars in regards to energy for the body.
In: Biology
Proteins are composed mostly of amino acids, and they have to be turned into glucose by removing the amino (nitrogen) group from them, then splitting that into ammonia (which gets excreted) and a “carbon skeleton” which is basically just a carbohydrate and can be processed in the same way. This is a very small part of energy production, though, unless you’re deliberately eating a keto diet or something like that.
As for carbohydrates (and sugars, since sugars are just simple carbohydrates), those get converted into three types of simple sugar (glucose, galactose and fructose) by digestive enzymes. The glucose goes directly into the bloodstream while the other two get converted to glucose in the liver. This is why simple sugars are bad for diabetics, because they get dumped rapidly into the bloodstream, while fructose (e.g. fruit sugar) is a little bit better because it takes time for it to get converted in the liver.
