Sucrose is broken down into glucose and fructose by the enzyme sucrase.
When sucrose (aka table sugar) is consumed it is hydrolyzed by sucrase into glucose and fructose .
glucose
No, there is not sucrose in feces. This is because sucrose is only in food that is not digested.
Small intestine
Glucose and sucrose are both as easily digested as the other by humans. This is because they are both simple sugars.
You get the molecule of glucose and fructose from the molecule of sucrose.
cellulose
Well water is not digested but i actually have no idea what I'm saying so forget this answer :)
Cellulose cannot be digested by humans.Cellulosecellulosehumans cannot digest cellulosecelluloseCelluloseCellulose (aka Fiber) can not be digested by humans because, we don't have the bacteria needed to break down cellulose. Sucrose, Maltose, and Fructose are all disaccharides (carbohydrates/sugars) and are all able to be broken down to glucose in the body.
Lactose and Glucose
Mainly carbohydrates like starch,sucrose are broken down to glucose to use in respiration.
Before our body cells can use cells they have to extract all the sucrose nutrients and place them in the pancreas for the hydrolization process which then transforms sucrose into another less sweet sugar so it can be digested after that it is placed in the heart and stored there to be used as energy
Carbon is an element. Sucrose, a sugar, is a compound ( a combination of elements ). Sucrose is composed of carbon, hydrogen and oxygen. Pure carbon is found in two forms, graphite (pencil lead) and diamond. Carbon and sucrose are very different in properties except for the fact that both can be burned in the presence of oxygen to yield CO2 (and water in the case of sucrose).
Whether "most" breads have sucrose as such is impossible to say. All breads have starches, which are broken down into sugars as they are digested. Many bread recipes include some form of sugar to encourage the yeast to rise. Many other bread recipes do not.
