Study Notes
Phospholipids and Water Interaction
- Polar heads of phospholipids interact with water; nonpolar tails do not.
Glucose Molecular Formula
- Linking three glucose molecules through dehydration reactions results in C18H32O16.
Flow of Genetic Information
- Genetic information in cells flows from DNA to RNA to protein.
Functional Groups
- Amino and carboxyl groups are classified as functional groups.
Hydrophobic Nature of Lipids
- Lipids are hydrophobic due to the presence of relatively nonpolar CH bonds.
Protein Structure Preservation
- Disrupting hydrogen bonds preserves the primary structure of proteins.
RNA vs. DNA
- The major difference between RNA and DNA is the type of sugar present.
Carbon Versatility
- The complexity and variety of organic molecules stem from the chemical versatility of carbon atoms.
Isomers
- Molecules with the same chemical formula but different three-dimensional shapes are known as isomers.
Condensation Reaction
- Another term for a condensation reaction is dehydration.
Nucleic Acid Polymers
- Nucleic acids are composed of nucleotide monomers.
Carbohydrate Polymers
- Carbohydrates consist of simple sugar monomers.
Protein Polymers
- Proteins are formed from amino acid monomers.
Alcohol Functional Group
- The functional group that contains alcohol is the hydroxyl group.
Thiols Characteristic Group
- Sulfhydryl groups are characteristic of thiols.
Energy Transfer Functional Group
- Phosphate groups play a major role in energy transfer.
Basic Functional Group
- The amino group behaves as a base.
Acidic Functional Group
- The carboxyl group functions as an acid.
Reactive Properties of Organic Molecules
- Variations in reactive properties of organic molecules are closely associated with the presence or absence of functional groups.
Components Varying in Amino Acids
- Different amino acids vary primarily in the components of the R group.
Common Elements in Organic Compounds
- Most organic compounds consist of carbon and hydrogen.
Bond Breaking Process
- The bonding between two monomers is broken during the process of hydrolysis.
