Study Notes
Four Major Classes of Organic Compounds
- Carbohydrates, Lipids, Proteins, Nucleic Acids are the four main classes of organic compounds.
Carbohydrates
- Composed of carbon, hydrogen, and oxygen (C + H + O).
- Serve as an immediate energy source for organisms.
- Water-soluble and include simple sugars known as monosaccharides (e.g., fructose, glucose).
- Disaccharides consist of two monosaccharides (e.g., sucrose, lactose).
- Polysaccharides are formed from multiple monomers (e.g., starch, glycogen) and serve as energy storage in plants and animals.
- Plant cell walls are primarily made of cellulose.
Lipids
- Made up of carbon, hydrogen, and smaller amounts of oxygen (C + H + small amounts of O).
- Function as long-term energy sources and burn slowly in the body.
- Examples include fats, oils, waxes, hormones, and steroids.
- Play crucial roles in forming cell membranes and providing waxy coatings on leaves.
- Can be classified as saturated or unsaturated fats.
Proteins
- Composed of carbon, hydrogen, oxygen, nitrogen (C + H + O + N), and sometimes sulfur.
- Built from monomers called amino acids; there are 20 different amino acids.
- Essential for building tissue and organ structural cells.
- Allow muscle contraction and contribute to pigmentation, such as eye color.
- Play a key role in the immune response by producing antibodies.
- Include enzymes that control the rate of chemical reactions.
Nucleic Acids
- Comprised of carbon, hydrogen, oxygen, nitrogen, and phosphorus (C + H + O + N + P).
- Highly complex molecules that serve as the genetic blueprint for life.
- The monomer of nucleic acids is the nucleotide.
- DNA is responsible for genetic information storage and is utilized to synthesize RNA.
- RNA plays a role in assembling amino acids to form proteins.
Importance of Carbon
- Carbon is vital for all known life on Earth due to its ability to form stable bonds with various elements, enabling diverse compound formation.
Energy Storage
- Carbohydrates and lipids are organic compounds that provide energy for organisms.
Genetic Information
- Nucleic acids are responsible for storing and transmitting genetic information.
