What are the 4 main types of macromolecules as discussed in class?
Carbohydrates, Lipids, Proteins, and Nucleic Acids
Cellulose and Chitin are what kind of Polysaccharide?
Structural Polysaccharides
Glycogen and Starch are what kind of Polysaccharides?
Storage Polysaccharides
What is the difference between an alpha and a beta glucose?
- location of the Hydroxyl functional unit about Carbon 1.- Alpha Glucose has the OH below- Beta has the OH Above
What is the main difference between Glycogen and Starch?
Starch found in PlantsGlycogen found in Animals
What is starch made up of, and which one is more branched?
Amylose and Amylopectin.Amylopectin is more branched.
What element does Chitin contain that differentiates it from the other carbohydrates?
Nitrogen
What type of linkage exists between two carbohydrates?
Glycosidic Linkage
What is the most abundant organic compound on Earth and what about it's monomers makes it special?
Cellulose...Composed of alternating/inverted Beta Glucose monomers.
What is the difference between a Saturated and Unsaturated fatty acid, and which one is healthier?
Saturated fatty acids: straight chains, no "kinks" Unsaturated fatty acids: opposite, contain kinks
Unsaturated fatty acids are much healthier.
What are the 4 types of Lipids?
Fats/Fatty AcidsPhospholipidsSteroidsWaxes
If a Phospholipid is exposed to water, what are the two possible structures it can create? What is the reason for this behaviour?
Micelle - Single Phospholipid LayerLiposome - Phospholipid Bilayer

Hydrophilic HeadHydrophobic Tail

12 for Children8 for Adults
What two functional groups make up Amino acids?
Amines and Carboxyl Groups.
What are the 3 classifications of Amino Acids?
PolarNon-PolarCharged
