This molecule consists of three sequentially bonded, tetrahedral (chiral) carbons. Label them C1-C2-C3 along the main chain:
1. C1 (R configuration) carries:
  - A hydroxyl group
  - A linear 10-carbon alkyl chain (n-decyl)
  - The bond to C2
2. C2 (S configuration) carries:
  - A hydroxyl group
  - The bond back to C1
  - The bond to C3
3. C3 (S configuration) carries two substituents:
  - An -N=C-O group (the nitrogen is double-bonded to the carbon, and that carboe is single-bonded to oxygen).
  - A methylene (-CH2-) group is connected to a phosphatediester linkage, which in turn is linked by a 2-carbon chain to a quaternary ammonium (-[N+](CH3)3). Specifically, the phosphate is tetrahedral with one double-bonded oxygen (P=O), one negatively charged oxygen (O-), and two ester bonds, where one to the methylene group and one to a two-methylene linker leading to the quaternary ammonium group.
