Chapter 2.3: Carbon Compounds
There are FOUR major MACROMOLECULES: CarbohydratesLipids Nucleic Acids Proteins
These macromolecules are large complex molecules called polymers that are built from many smaller molecules called monomers
What is a MONOMER? “Mono” means? one A monomer is a single unit of a macromolecule
What is a POLYMER? “Poly” means? many A polymer is many monomers linked together to build the macromolecule
Scary Lego man is made out of many building blocks. Each Lego piece is like a monomer and the scary Lego man is like a polymer.
The process of linking many monomers together to form a polymer is called POLYMERIZATION
“Poly” means? Many “mer” means? Think about the word “merge” To combined “ization” is the suffix for? A process
The monomer of carbohydrates are called MONOSACCHARIDES Examples of monosaccharides are Glucose: found in many sugars Galactose: found in milk sugars Fructose: found in fruit sugars
If you polymerize many monosaccharides you will form the polymer of carbohydrates called: POLYSACCHARIDES Examples of polysaccharides are Glycogen: animal starch Starch: plant starch (potato) Cellulose: plant structures
The monomers that build proteins are called Amino Acids The polymer of proteins is the protein chain created by the polymerization of amino acids
Another name for a protein is a polypeptide because the amino acids are held together by a specific covalent bond called a peptide bond
The monomers that build nucleic acids are called Nucleotides The polymer of nucleic acids is DNA or RNA created by the polymerization of nucleotides
