Why are saturated fats solid at room temperature?

• They have a higher melting point

• They contain more double bonds

• They have a lower melting point

• They contain more oxygen atoms

Why are all monosaccharides and disaccharides soluble in water?

• They have a hydrophobic nature

• They contain more carbon atoms

• They have a hydrophilic nature

• They contain more nitrogen atoms

How is it possible that a polysaccharide molecule may have one reducing end and many non-reducing ends?

• Due to the presence of different types of sugars

• Due to the high water content

• Due to the branching structure of the molecule
