  • Fatty Acid
    A molecule composed of a hydrocarbon chain with a carboxylic acid group, serving as a fundamental lipid component.
  • Nomenclature
    A systematic approach for assigning names to molecules, ensuring clarity and consistency in chemical identification.
  • Common Naming System
    A traditional method using familiar names, such as oleic acid, to identify specific fatty acids.
  • Systematic Naming System
    A method that uses precise chemical descriptors, like 9-octadecanoic acid, to specify fatty acid structure.
  • Shorthand Naming System
    A concise format, such as 18:1 Δ9, that summarizes carbon count, double bonds, and their positions in fatty acids.
  • Carbon Atom
    A fundamental element in fatty acid chains, counted to determine the molecule's length and structure.
  • Double Bond
    A structural feature in fatty acids, denoting unsaturation and influencing physical and chemical properties.
  • Colon
    A punctuation mark used in shorthand notation to separate the number of carbon atoms from double bonds.
  • Superscript
    An exponent-like notation placed above the Greek letter delta to indicate the position of double bonds.
  • Greek Letter Delta
    A triangular symbol in shorthand notation, marking the location of double bonds within fatty acid chains.
  • Carboxylic Acid
    A functional group at one end of fatty acids, serving as the starting point for carbon numbering.
  • Alpha Carbon
    The carbon atom directly adjacent to the carboxylic acid group, labeled as carbon 2 in fatty acids.
  • Linoleic Acid
    A fatty acid with 18 carbon atoms and two double bonds at carbons 9 and 12, commonly used as an example.
  • Hydrocarbon Chain
    A sequence of carbon atoms bonded together, forming the backbone of fatty acids.
