Ligninverbindungen
Ligninverbindungen, often simply referred to as lignin, are complex organic polymers found in the cell walls of plants. They are a crucial component of the structural integrity of vascular plants, providing rigidity and strength. Lignin is a heterogeneous polymer, meaning it is composed of different building blocks, primarily phenylpropane units linked together in a three-dimensional network. This complex structure makes lignin resistant to degradation by many enzymes and chemicals.
The biosynthesis of lignin occurs through the oxidative coupling of monolignols, which are phenolic compounds derived
Beyond its structural role, lignin also plays a part in the plant's defense mechanisms against pathogens and
