Chitin Meaning: Definition, Examples, and Translations
๐ฆ
chitin
[หkaษชtษชn ]
Definition
biological structure
Chitin is a long-chain polymer of N-acetylglucosamine, a derivative of glucose. It serves as a critical structural component in the cell walls of fungi and the exoskeletons of insects and crustaceans. This biopolymer provides strength and rigidity to these organisms, playing a crucial role in their protection and maintaining their shape. Chitin is the second most abundant biopolymer after cellulose, making it essential for various ecological processes.
Synonyms
N-acetylglucosamine, poly-N-acetylglucosamine.
Examples of usage
- The exoskeleton of crabs is composed of chitin.
- Fungi use chitin to build their cell walls.
- Chitin is a significant component in the structure of insect cuticles.

- Certain diets incorporate chitin-rich foods, such as shellfish, emphasizing its nutritional value and unique texture.
Origin of 'chitin'
Main points about word origin
- The term 'chitin' comes from the Greek word 'chiton', meaning 'tunic' or 'coat', which reflects its protective function.
- It was first identified in 1811 by French chemist Henri Braconnot, who isolated it from fungal cell walls and later from insect shells.
The term 'chitin' is derived from the Greek word 'chitos,' which means 'skin' or 'shell.' It was first coined in 1811 by the French chemist Franรงois Pierre Nicolas Boullard. Initially, the substance was identified in the context of fungal cell walls, but its role in the exoskeletons of arthropods was later recognized. Chitin's significance in biological sciences has grown, leading to extensive studies on its properties and potential applications, including its use in medicine and materials science. The study of chitin has expanded from merely understanding its presence in nature to exploring its capabilities in biocompatibility and biodegradability.
