One of the following is not a physical property of monosaccharides?

One of the following options is not a physical property of monosaccharides: - They are highly vital to the exploration of metals Monosaccharides are simple sugars that play important roles in biology and biochemistry. They are characterized by several physical properties: - Monosaccharides get charred when heated, meaning that they undergo a chemical reaction when exposed to high temperatures and form a black, charred residue. - Monosaccharides are water-soluble, sweet substances, which means that they dissolve in water and have a sweet taste. Examples of monosaccharides include glucose, fructose, and galactose. - They can be reduced to sugar alcohols, meaning that they can undergo a chemical reduction reaction and form compounds known as sugar alcohols. In conclusion, the option "They are highly vital to the exploration of metals" is not a physical property of monosaccharides.
