Study Notes
Carbon Compounds
- Organic compounds contain carbon and are essential to living organisms, while most inorganic compounds lack carbon.
- Carbon atoms can form four covalent bonds, enabling diverse simple and complex organic compounds.
- Functional groups are specific groupings of atoms that modify molecular properties and influence chemical reactions.
- Condensation reactions link monomers to create polymers, releasing water as a by-product; hydrolysis uses water to break polymers back into monomers.
- Adenosine triphosphate (ATP) serves as an energy currency, storing and releasing energy for cellular functions.
Molecules of Life
- Carbohydrates consist of carbon, hydrogen, and oxygen in a 1:2:1 ratio, providing energy and structural support in organisms.
- Monosaccharides are the simplest carbohydrate units, serving as the building blocks for larger carbohydrates.
- Disaccharides result from the joining of two monosaccharides, while polysaccharides consist of three or more monosaccharides.
- Proteins are complex molecules made primarily of carbon, hydrogen, oxygen, and nitrogen, playing varied roles in structure, defense, and catalysis.
- Amino acids, the monomers of proteins, determine the protein's structure and function based on their sequence.
- A dipeptide forms when two amino acids link through peptide bonds, while a polypeptide is a longer chain of amino acids.
- Enzymes accelerate chemical reactions and bind to specific substrates, altering the enzyme's shape and lowering activation energy.
Lipids
- Lipids are hydrophobic molecules that store energy and are vital components of cell membranes.
- Most lipids contain fatty acids, which have a hydrophilic (water-attracting) end and a hydrophobic (water-repelling) end.
- Triglycerides, a type of lipid, consist of three fatty acids bonded to one glycerol molecule.
- Phospholipids are crucial for cell membranes, comprised of two fatty acids and one glycerol, providing structural integrity.
