The study of all compounds that contain bonds between carbon atoms
Carbon-based molecules. Found in living things
Do not contain carbon (water, salts ect. ). Found in living things
Carbon atoms can make ____ bonds
Large, complex molecules built of smaller/similar molecules
Building blocks of polymers
Build polymers from monomers. One molecule of water must be removed to join to join subunits.
The breakdown of molecules with H2O
What are the 4 categories of macromolecules?
Carbohydrates, Protein, Lipids, and Nucleic Acid
Small sugars= Monosaccharides
Monomer of a carbs
Molecular formula= C6H12O6
Function= Fuel for cellular work; short term energy. Glucose, fructose, galactose. same formula diff properties
Molecules with same molecular formula, different structural formula
sucrose, lactose, maltose
Chemical Formula= C12H22O11
Polymers of a monosaccharides linked together. Function: Storage molecules, Structural compounds
Composed of C, H, and O
Diverse in function
Insoluable to water
Composite molecule rather than polymer
Fear of water
Component of triglycorides and phospholipids
Structure of Fatty Acid
Straight carbon that is hydrophobic (tail)
carboxyl group that is hydrophilic (head)
Made of 1 glycol and 3 fatty acids
Function: Long term energy storage in animals, isolation, and protection
Stacks well, solid at room temp.
All single bonds between C atoms
At least 1 double bond between a pair of C atoms
Dont stack well
Liquid at room temp
2 fatty acid tails and a phosphate group attach to the glycerol molecule
Composed of 4 fused rings. No fatty acids.
Cholesterol for cell membrane
Structure: Fatty acid chain+ alchol chain
Function: Protective coating/ water proofing
