🧪 Aromatic Structure Breakdown
Despite its name, Aldehyde C-18 is technically a lactone (γ-lactone), not an aldehyde. Its saturated ring structure is responsible for the characteristic creamy and fatty scent. It is structurally similar to other lactones like γ-Decalactone (peachy) and δ-Undecalactone (apricot-like).
