Study Notes
Lipids
- Organic compounds that are insoluble in water yet soluble in organic solvents.
- Include natural oils, waxes, and steroids.
- Key types: fats, oils, and waxes.
Carbohydrates
- Organic compounds made up of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1.
- Commonly serve as energy sources and structural components in living organisms.
Biological Macromolecules
- Large complex molecules essential for biological functions; contrast with smaller micromolecules.
- Four main types: proteins, nucleic acids, carbohydrates, and lipids.
Nucleic Acids
- Complex compounds found in all living cells and viruses.
- Composed of nucleotides, containing purines, pyrimidines, carbohydrates, and phosphoric acid.
Proteins
- Substances consisting of amino acids, which are vital for various biological functions.
- Composed of carbon, hydrogen, oxygen, and nitrogen.
Monomers
- Small molecules that can join together through chemical bonds to form larger structures known as polymers.
- Serve as the building blocks of biological macromolecules.
Polymers
- Compounds formed by linking repeated simple monomers into larger molecules.
- Naturally occurring (like DNA and proteins) or synthetic (like plastics).
Lipid Overview
- Essential for storing energy, signaling, and acting as structural components of cell membranes.
Polymer Overview
- Polymers can be natural (e.g., proteins, starch) or synthetic (e.g., nylon, plastics) and play critical roles in various fields, including biology and materials science.
Protein Enzymes
- Proteins that act as catalysts to accelerate biochemical reactions in living organisms.
- Essential for metabolic processes and regulation within cells.
Elements of Life
- Key elements include carbon, hydrogen, nitrogen, oxygen, phosphorous, and sulfur, crucial for forming biological macromolecules.
