Correct Answer - Option 3 : Dehydration

The correct answer is Dehydration.

  • Dehydration
    • 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 polyethene terephthalate (PET), or the creation of large biological molecules such as carbohydrate polymers and triglycerides.
    • The addition of carbohydrates to a molecule is via the formation of a glycosidic bond, which is a form of dehydration synthesis.
    • There are four types of glycosidic bonds, the C-, S-, N- and O-glycosidic bonds.
    • The O-glycosidic bond is most commonly seen.
    • The peptide bond is an amide linkage that is formed between the COOH group of one amino acid, and the NH2 group of another amino acid.
    • A water molecule is always eliminated informing of a peptide bond.
    • A sugar molecule has several reactive hydroxyl groups.
    • The hydroxyl group of 1st C atom forms a linkage with hydroxyl groups of another sugar molecule, during this a water molecule is eliminated. In this process of dehydration synthesis, the bond formed is called a glycosidic bond. Hence, Option 3 is correct.
    • In polysaccharides, the individual monosaccharide is linked by a glycosidic bond.
    • This bond is formed between two carbon atoms of two adjacent monosaccharides.
    • A glycosidic bond is a type of covalent bond that joins a carbohydrate molecule to another group, which may or may not be another carbohydrate. Glycosidic bonds are formed by dehydration.

  • Hydration reaction
    • In chemistry, a hydration reaction is a chemical reaction in which a substance combines with water.
    • Inorganic chemistry, water is added to an unsaturated substrate, which is usually an alkene or an alkyne.
    • This type of reaction is employed industrially to produce ethanol, isopropanol, and butane-2-ol.
  • Annotation
    • An annotation is extra information associated with a particular point in a document or other piece of information.
    • It can be a note that includes a comment or explanation.
    • Annotations are sometimes presented in the margin of book pages.
  • Rehydration
    • The process of restoring lost water (dehydration) to the body tissues and fluids.
    • Prompt rehydration is imperative whenever dehydration occurs, from diarrhoea, exposure, lack of drinking water, or medication use.
    • Rehydration can be by the oral route or by the intravenous administration of fluids.
