glucose
No, it can be broken down.
When a carbohydrate is hydrolyzed, it breaks down into simpler sugar units, typically monosaccharides like glucose or fructose. This process involves the addition of water, which helps cleave the glycosidic bonds between the sugar molecules. Depending on the type of carbohydrate, hydrolysis can yield varying combinations of monosaccharides. For example, the hydrolysis of sucrose produces glucose and fructose.
There is no simpler form...
Yes, milled corn contains carbohydrate. All grains, in whatever form, contain carbohydrate.
Complex carbohydrate in the form of starch from the wheat-grain.
Amylase breaks starch (a polysaccharide - complex carbohydrate) down into maltose (a disaccharide - simpler sugar).
It is 74, exactly as in the question. No other form is simpler.
Monosaccharides
A carbohydrate is a nutrient which is non-essential. It provides the body with easy accessed energy in the form of glucose.
Cellulose
glucose is the common form of simple sugar
Although carbohydrates (saccharides) can combine with other macromolecules to form more complex molecules like glycoproteins and DNA, the most common task is breaking into simpler sugars (monosaccharides and disaccharides) to transfer energy in the form of ATP, which can then be used as a ready source of energy for the cell.
