Compounds that contain CARBON are called organic.
Macromolecules are large organic molecules.
Carbon has 4 electrons in outer shell.
Carbon can form covalent bonds with as many as 4 other atoms (elements).
Usually with C, H, O or N.
Large organic molecules.
Also called POLYMERS.
Made up of smaller “building blocks” called MONOMERS.
4. Nucleic acids (DNA and RNA)
Question: How Are Macromolecules Formed?
Answer: Dehydration Synthesis
Also called “condensation reaction”
Forms polymers by combining monomers by “removing water”.
Question: How are Macromolecules separated or digested?
Separates monomers by “adding water”
Small sugar molecules to large sugar molecules.
Monosaccharide: one sugar unit
Examples: glucose (C6H12O6)
Disaccharide: two sugar unit
Polysaccharide: many sugar units
Examples: starch (bread, potatoes)
glycogen (beef muscle)
cellulose (lettuce, corn)
