Study Notes
Carbon and Molecular Diversity of Life
- Cells are composed mostly of water (70-95%) and carbon-based compounds.
- Carbon is essential for forming large, complex, and diverse molecules in living organisms.
- Proteins, DNA, carbohydrates, and other crucial molecules are carbon-based.
Organic Chemistry
- Organic chemistry is the study of carbon compounds.
- Organic compounds range from simple to complex molecules.
- Most organic compounds also contain hydrogen atoms.
- A crucial experiment disproved vitalism. Vitalism proposed that organic compounds can only be produced by organisms, but chemists proved otherwise.
Carbon's Properties
- Carbon has four valence electrons, allowing it to form four covalent bonds with various other atoms. This ability is called tetravalence, enabling the formation of large and complex molecules.
- Carbon atoms in a molecule often have a tetrahedral shape, and when two carbon atoms are joined with a double bond—the shape becomes flat.
The Shapes of Three Simple Organic Molecules:
- Methane: CH₄, tetrahedral shape.
- Ethane: C₂H₆, straight chain.
- Ethene (ethylene): C₂H₄, double bond, flat shape.
Covalent Compatibility
- Carbon's electron configuration enables covalent bonds with diverse elements.
- The valences of carbon and its frequent partners (hydrogen, oxygen, and nitrogen) form the "building code" of living molecules.
Major Elements of Organic Molecules
- Elements like Hydrogen (valence=1), Oxygen (valence=2), Nitrogen (valence=3), and Carbon (valence=4) are crucial in organic molecules.
Carbon Dioxide and Urea
- Carbon atoms can bond to atoms other than hydrogen, for example in carbon dioxide (CO₂) and urea (CO(NH₂))₂.
Molecular Diversity
- Carbon chains form the skeletons of most organic molecules.
- The length and shape of carbon chains vary, contributing to diversity in organic molecules. (Branches, double bonds, and rings are examples of structural variation).
Isomers
- Isomers are compounds with the same molecular formula but different structures and properties.
- Types of isomers include:
- Structural isomers: Different covalent arrangements of atoms.
- Geometric isomers: Same covalent arrangements but differences in spatial arrangement.
- Enantiomers: Mirror images of each other.
Pharmaceutical Importance of Enantiomers
- Different effects of enantiomers are important in pharmaceuticals. Two enantiomers of a drug can trigger varied responses in the body.
- Organisms are sensitive to slight variations in molecular structures.
Chemical Groups
- Functional groups are components of organic molecules often involved in chemical reactions.
- The number and arrangement of functional groups determine a molecule's properties.
Seven Functional Groups
- Seven major groups—hydroxyl, carbonyl, carboxyl, amino, sulfhydryl, phosphate, and methyl—are key in biological processes.
- Properties of each group are discussed (acidity, polarity, base properties, cross-linking).
ATP
- Adenosine triphosphate (ATP) is the primary energy-transferring molecule.
- ATP consists of adenosine attached to three phosphate groups.
- ATP's release of energy is critical for cellular processes. Conversion of ATP to ADP and inorganic phosphate releases energy.
