Water
State the Properties of Water
Water is polar, a good solvent and has high cohesion.
What are Macromolecules?
Macromolecules are large molecules essential for life.
What is the monomer of Protein?
Amino acids
Which chemical reaction is this?
A chemical process where two molecules join together, forming a covalent bond and releasing water as a byproduct.
Condensation reaction
What does water's polarity allow water to do?
Water’s polarity allows the hydrogen molecule to form hydrogen bonds with other water molecules and polar substances.
List the four macromolecules.
The four macromolecules are protein, carbohydrates, nucleic acid and lipids.
What is the most common monosaccharide used to make carbohydrate polymers?
Glucose
Fill in the blank.
_______ is a chemical reaction in which water is used to break down a compound, splitting the polymer into its monomers.
Hydrolysis
Why is water a good solvent?
The polar nature of water allows it to dissolve ions and polar molecules effectively.
Which macromolecules have only two monomers?
List them.Lipids.
Glycerol and fatty acids
What is the Structure of Monomers and Polymers?
A monomer is a small molecule and a polymer is a long-chain molecule made up of a repeated pattern of monomers.
Give an example of a condensation reaction using glucose.
Glucose molecules condense to form starch, releasing water.
C6H12O6 -----> C6H10O5 + H2O
What causes high cohesion in water?
Due to the hydrogen bonding between its molecules, water has a high cohesion which forms an unbreakable chain of water molecules.
What are macromolecules made of?
Macromolecules are made up of single units known as monomers that are joined by covalent bonds to form larger polymers.
What is are the monomers of Lipids bonded together by?
Ester bonds
Explain Water Density.
Water’s solid state and matter is ice, which is less than liquid water. When Water freezes it expands and become less dense due to the formation of a lattice structure in the ice and each water molecule is hydrogen bonded to four other water molecules.
What is are the monomers of Nucleic Acids bonded together by?
Phosphodiester bonds
