Study Notes
- The text discusses the importance of biomolecules in the structure and function of cells and organisms.
- Biomolecules are large molecules also known as macromolecules, comprised of carbohydrates, lipids, proteins, and nucleic acids.
- Carbohydrates are found in various food sources like bread, pasta, fruit, and vegetables. Their monomer is a monosaccharide, such as glucose, which is crucial for cellular respiration and making ATP.
- Linked monosaccharides form disaccharides, while many are joined to create polysaccharides. Carbohydrates serve as a major energy source and storage form (starch/glycogen).
- Lipids include fats and oils, like butter and olive oil. They have monomers of glycerol and fatty acids and are generally hydrophobic.
- Lipids are essential for cell membrane structure, long-term energy storage, insulation (heat and electrical), and acting as hormones.
- Proteins consist of amino acids, and their importance includes forming structures (muscle tissue, hair, collagen), functions in cell membranes (channels and receptors), and roles in enzymes, antibodies, and hormones.
- Nucleic acids (DNA and RNA) have monomers called nucleotides. They contain all genetic information and are vital for coding traits.
- Nucleic acids are found in most living organisms and play a significant role in storing genetic information.
- CHO mnemonic can help remember the common elements in biomolecules: Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N), and Phosphorus (P).
- The arrangement of these elements in biomolecules impacts their function.
- The text encourages staying curious about biology.
Explore the significance of carbohydrates, lipids, proteins, and nucleic acids in cell structure and function. Learn about their monomers, sources, and roles in energy storage, membrane structure, genetic coding, and more.
