A lipids polymer, more commonly referred to as a polymeric lipid or a lipid complex, is not a polymer in the traditional sense like proteins or plastics. Traditional polymers consist of long, repeating chains of identical or similar molecular units. Instead, lipid polymers often refer to complex molecular assemblies formed by lipids, which include fats, oils, waxes, and certain vitamins. These assemblies can form structures such as micelles, liposomes, or bilayers, which are essential for biological functions like cell membrane formation and intracellular transport. Despite not being polymers by strict definition, these lipid assemblies exhibit polymer-like behavior in how they interact and form structures on a nanoscopic scale. Understanding these lipid complexes is crucial in fields like pharmacology and nanoengineering, where they are used for drug delivery systems and creating materials with unique properties.

Several trees naturally produce decay-resistant resins, but one of the most notable is the cedar tree. Cedar wood contains oils and phenolic compounds that repel insects, fungi, and decay. This makes it an excellent choice for outdoor furniture, shingles, and construction purposes. Another example is the teak tree, valued for its high oil content that provides exceptional moisture resistance, making it ideal for shipbuilding and outdoor furniture. Additionally, the Redwood tree possesses similar qualities, with its tannin-rich wood offering protection against decay and insects. These natural resins extend the life of wood products significantly compared to non-resistant varieties, underscoring the importance of these trees in construction and manufacturing industries focusing on durability and sustainability.
