Structure of Water and Hydrogen Bonding

🎥 Live Stream Replay - Structure of Water & Hydrogen Bonding

  • The sequence and make up of all molecules determine the property of that molecule.
  • Water is a unique molecule that is polar due to an unequal distribution of charge. The properties of water and essential to the existence of life on earth.
  • Water is able to form hydrogen bonds with other water molecules due to its polarity, and this contributes to the properties of cohesion, adhesion, and surface tension.

Elements of Life

🎥 Live Stream Replay - Elements of Life

  • The elements of life are organized on the periodic table.
  • The elements most common to biological molecules are carbon, nitrogen, hydrogen, oxygen, and phosphorus.

Introduction to Biological Macromolecules

🎥 Live Stream Replay - Introduction to Biological Macromolecules

  • All living organisms are made up of proteins, lipids, carbohydrates, and nucleic acids.
  • Monomers are bound together in order to form these polymers.
  • Hydrolysis and dehydration synthesis are used to cleave and form covalent bonds between monomers

Properties of Biological Molecules

🎥 Live Stream Replay - Properties of Biological Molecules

  • The way in which a polymer is assembled contributes to the overall function of that polymer. This includes:
    • Nucleotides in nucleic acids, the amino acid order in proteins, sugar monomers in carbohydrates, and the saturation of lipids

Structure and Function of Biological Molecules

🎥 Live Stream Replay - Structure & Function of Biological Molecules

  • Amino acids may be polar, nonpolar, sulfur-containing, acidic, or basic. The function of a protein depends on what amino acids make up a protein.
  • The order of nucleotides in DNA make up its genetic code. DNA is antiparallel, forms a double helix, and contains hydrogen bonds between nucleotides.
  • Lipids are nonpolar and hydrophobic. The presence of double bonds in lipids contributes to whether or not it is a saturated or unsaturated fat and contributes to its function.
  • Carbohydrates are broken down to make energy. The complexity of the carbohydrate structure determines the amount of energy needed to break it down.

Nucleic Acids

🎥 Live Stream Replay - Nucleic Acids

  • DNA and RNA are similar structures with the exceptions of a few key differences.
    • DNA is usually double stranded whereas RNA is usually single stranded.
    • DNA has a deoxyribose sugar, whereas RNA has a ribose sugar.
    • DNA has thymine, adenine, cytosine, and guanine, whereas RNA replaces thymine with uracil.
