The chemical formulae which represents a disaccharide from the answer choice above is C10H18O9.
It is called Ribo-ribo disaccharide ( C10H18O9 ).
Disaccharides are substances which are composed of two molecules of simple sugars (monosaccharides) linked to each other. They are also known as double sugar.
They refer to any sugar, such as sucrose, maltose and lactose, consisting of two monosaccharides combined together.
Monosaccharide on the other hand, refers to simple sugar such as glucose, fructose or deoxyribose that has a single ring.
So therefore, chemical formulae which represents a disaccharide from the answer choice above is C10H18O9.
