Structure and Function of Large Biological Molecules
Carbohydrates
Monomers
Monosaccharide
Glucose
Polymers
Polysaccharide
Starch
Definition: Storage polysaccharide in plants
Glycogen
Definition: Storage polysaccharide in animals
Cellulose
Definition: Structural polysaccharide in plants
Insoluble fiber
Definition: Fiber that does not dissolve in water
Chitin
Definition: Structural polysaccharide in arthropods and fungi
Examples
Aldose
Ketose
Function
Immediate energy
Definition: Primary source of energy
Lipids
Polymer
Triglyceride
Definition: Three fatty acids attached to glycerol by ester linkage
Examples
Oil
Waxes
Steroids
Monomer
Glycerol
Definition: Three-carbon alcohol with hydroxyl groups attached to each carbon
Fatty Acids
Definition: Carboxyl group attached to a long carbon skeleton
Unsaturated fat
Definition: One or more double bonds, liquid at room temp
Saturated fat
Definition: Maximum number of hydrogen bonds, no double bonds, solid at room temp
Phospholipids
Definition: Two fatty acids and phosphate group attached to glycerol; The fatty acid tails are hydrophobic, the phosphate group and its attachments are hydrophilic
Function
Long-term energy storage
Protection/insulation
Definition: Organic compounds that are hydrophobic, meaning they mix poorly with water if at all
Proteins
Polymer
Polypeptide
Examples
Meats
Nut products
Enzymes
Dehydration Reaction
Definition: Two monomers bond together by the breaking of a water molecule
Hydrolysis
Definition: Polymers break apart by gaining a water molecule
Monomer
Amino Acids
Function
Building structures
Organization
Primary
Secondary
Tertiary
Quaternary
Definition: Essential organic compounds made up of amino acids
Nucleic Acids
Monomer
Nucleotide
Pyrimidine
Cytosine, Thymine, Uracil
Purine
Adenine, Guanine
Polymer
DNA
Double helix
Palindromic Sequence
Definition: The sequence on one strand of DNA matches the sequence on a complementary strand
RNA
Protein synthesis
Transcription
Definition: DNA is converted into mRNA by RNA polymerases
Translation
Definition: mRNA is decoded in a ribosome to make a polypeptide
Definition: Process where cells build proteins for growth, function and repair
Example
ATP
Function
Macromolecules that provide genetic information
Definition: Stores genetic information
