  • Nonpolar Amino Acids
    Group of seven amino acids with hydrophobic R groups lacking terminal electronegative atoms, making them water-fearing.
  • Hydrophobic R Group
    Side chain that avoids water due to absence of terminal electronegative atoms, contributing to nonpolarity.
  • Glycine
    Amino acid with the smallest R group, consisting of a single hydrogen atom, allowing it to fit into tight spaces.
  • Alanine
    Amino acid with a simple methyl group as its R group, serving as a structural leader among chiral amino acids.
  • Valine
    Amino acid whose R group forms a V shape, essentially an alanine with two methyl groups branching off.
  • Leucine
    Amino acid with an R group that is a loose extension of valine, featuring an extra methylene group for added flexibility.
  • Isoleucine
    Isomer of leucine with a lopsided valine-like R group, same atoms but different arrangement, creating asymmetry.
  • Methionine
    Amino acid with an R group resembling an M shape, containing a methylthiol group with a sulfur atom.
  • Proline
    Amino acid with a cyclic R group that loops back to the amino group, unique for its pentagon-like structure.
  • Methyl Group
    Functional group consisting of CH3, present in alanine and part of methionine's R group.
  • Methylene Group
    Functional group consisting of CH2, found in the extended chains of leucine and proline.
  • Methylthiol Group
    Functional group in methionine's R group, combining a methyl group and a sulfur atom.
  • Isomer
    Molecule with identical atom types and counts as another, but differing in arrangement, as seen in isoleucine and leucine.
  • Cyclic Structure
    Ring-like configuration in proline's R group, connecting back to the amino group and altering backbone properties.
  • Mnemonic
    Memory aid, such as 'GAV LIMP,' used to recall the seven nonpolar amino acids efficiently.
