Study Notes
- Biomolecules are large molecules necessary for life, including Carbohydrates, Lipids, Proteins, and Nucleic Acids.
- Carbohydrates serve as a major energy source for cells, with glucose being a key monosaccharide used in cellular respiration.
- Lipids, including fats and oils, are hydrophobic and play roles in long-term energy storage, insulation, membrane structure, and hormone production.
- Proteins, made up of amino acids, are vital for tissue structure, cell membrane function, enzyme activity, and immune response.
- Nucleic acids like DNA and RNA are comprised of nucleotides and carry genetic information essential for cell traits and functions.
- Plants have cell walls made of carbohydrates like cellulose, while lipid structures form cell membranes and play roles in insulation and hormone production.
- The mnemonic "CHONP" helps remember the major elements in biomolecules: Carbon, Hydrogen, Oxygen, Nitrogen, and Phosphorus.
