Study Notes
Organic Chemistry
- Organic chemistry studies organic compounds.
- All organic compounds contain carbon.
- Many organic compounds come from living things.
- Most compounds found in nature are organic.
Carbohydrates
- Carbohydrates contain carbon, hydrogen, and oxygen in a 1:2:1 ratio.
- Sugars and starches are carbohydrates.
- Living things use carbohydrates for energy and structural support.
Monosaccharides
- Simplest carbohydrates, also called simple sugars.
- Examples: glucose and fructose
Disaccharides
- Two monosaccharides bonded together.
- Examples: sucrose (glucose + fructose), lactose (glucose + galactose), maltose (glucose + glucose)
Polysaccharides
- Large polymers of linked monosaccharides.
- Examples: starch (wheat, rice, corn, potatoes), cellulose (plant structural support), glycogen (animal energy storage), and chitin.
Lipids
- Lipids include fats, oils, waxes, and steroids.
- Lipids generally contain carbon, hydrogen, and oxygen, but in different ratios compared to carbohydrates.
Fats
- Composed of glycerol and three fatty acids.
- Used for energy storage and insulation.
- Excess carbohydrates are converted to fats.
- Fatty acid structure determines fat characteristics.
- Approximately 30 fatty acids are in animals.
Other Lipids
- Phospholipids: key components of cell membranes, controlling movement in and out of cells.
- Steroids: composed of four linked carbon rings; examples include cholesterol and hormones.
- Waxes: composed of fatty acids and alcohols.
Proteins
- Proteins are organic compounds composed of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur.
- Essential for all living things (e.g., muscles, hair, skin).
- Proteins are polymers of amino acids.
Amino Acids
- Building blocks of proteins.
- Twenty different amino acids are used to make proteins.
- Amino acid structure (including the side group) defines the amino acid.
- Amino acids are linked together by peptide bonds.
Protein Functions
- Movement (e.g., actin and myosin in muscle fibers)
- Structure (e.g., collagen)
- Biochemical control (e.g., enzymes)
- Transport (e.g., hemoglobin)
- Storage (e.g., casein in milk)
- Regulation (e.g., hormones)
Nucleic Acids
- Large, complex molecules composed of carbon, hydrogen, oxygen, nitrogen, and phosphorus.
- DNA and RNA are examples.
- DNA (deoxyribonucleic acid) is the genetic material.
- RNA (ribonucleic acid) plays various cellular roles.
- Nucleic acids can be linear, branched, or cyclical.
- Monomers form polymers.
- Chemical reactions (dehydration synthesis, hydrolysis) build or break molecules.
