Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
what compound is LOST in the reaction that links two monosaccharides?
A
water
B
oxygen
C
hydrogen
D
carbon
Explanation: 

Detailed explanation-1: -Answer and Explanation: The reaction that links two monosaccharides together is called dehydration synthesis. During this type of reaction one oxygen atom and two hydrogen atoms are removed from the monosaccharides as water. To dehydrate means to remove water, so this type of reaction removes one water molecule.

Detailed explanation-2: -The two monosaccharides are bonded via a dehydration reaction (also called a condensation reaction or dehydration synthesis) that leads to the loss of a molecule of water and formation of a glycosidic bond.

Detailed explanation-3: -The joining of two monosaccharides takes place through the formation of a glycosidic bond, a type of condensation reaction. The carbon of one sugar (usually the carbon in position 1) reacts with the hydroxyl moiety of a second sugar molecule with the concomitant loss of a water molecule.

Detailed explanation-4: -Two monosaccharide units can be joined together by a glycosidic bond-this is the fundamental linkage among the monosaccharide building blocks found in all oligosaccharides. The glycosidic bond is formed between the anomeric carbon of one monosaccharide and a hydroxyl group of another.

Detailed explanation-5: -Monosaccharides are quite soluble in water because of the numerous OH groups that readily engage in hydrogen bonding with water.
