Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When two sugar molecules combine they release a water molecule in a process called
A
dehydration synthesis
B
hydrolysis
C
triphosphate
D
macromolecule
Explanation: 

Detailed explanation-1: -In the dehydration synthesis reaction above, two molecules of the sugar glucose (monomers) combine to form a single molecule of the sugar maltose. One of the glucose molecules loses an H, the other loses an OH group, and a water molecule is released as a new covalent bond forms between the two glucose molecules.

Detailed explanation-2: -Dehydration synthesis involves the formation of new chemical bonds between two molecules which leads to the formation of new compounds. A reaction occurs with the loss of water molecules at each step. The loss of water molecules can occur due to reactions between two functional groups like –OH, -NH2 or –COOH.

Detailed explanation-3: -Dehydration synthesis is the creation of larger molecules from smaller monomers where a water molecule is released. This can be used in the creation of synthetic polymers such as polyethylene terephthalate (PET), or the creation of large biological molecules such as carbohydrate polymers and triglycerides.

Detailed explanation-4: -Two glucose molecules can be linked together through a dehydration synthesis reaction to form a disaccharide called maltose. This process can be repeated to form polysaccharides, such as starch and glycogen.

Detailed explanation-5: -In biology, dehydration synthesis forms large polymers commonly referred to as biological macromolecules. These include molecules like proteins, lipids (fatty acids), nucleic acids (DNA and RNA), and carbohydrates.
