What else can I help you with?
Which polysaccharide is most similar to chitin?
Cellulose
What is a modified form of cellulose found in the exoskeletons of insects and crustaceans?
There is no such tihng as a modified form of cellulose, but the word you are looking for is probably chitin, another organic molecule which is very similar to cellulose. Chitin is the second most abundant organic molecule on earth, second only to cellulose.
How are cellulose and chitin similar?
cellulose and chitin are considered structual polysaccharides because they form tough structual cell walls in plants for example. They are the polysaccharides that are used to build a structual frame.
What is the polymer of a carbohydrate?
The polymer of a carbohydrate is called a polysaccharide. Polysaccharides are long chains of monosaccharide units (simple sugars) linked together through glycosidic bonds. Examples of polysaccharides include starch, cellulose, and glycogen.
Polysaccharide that makes up cell walls of fungi?
The primary polysaccharide that makes up the cell walls of fungi is called chitin. Chitin is a long-chain polymer of N-acetylglucosamine and provides structural support and protection to fungal cells. It is similar in function to cellulose in plant cell walls.
What is a list of natural polymers?
Natural polymers include cellulose, starch, chitin, proteins (such as collagen and silk), and DNA. These polymers are derived from renewable resources and are biodegradable, making them environmentally friendly alternatives to synthetic polymers.
How is chitin different then cellulose?
Chitin is a structural polysaccharide found in the exoskeleton of arthropods, while cellulose is a structural polysaccharide found in plants, providing rigidity to cell walls. Chitin contains nitrogen, making it tougher and more flexible than cellulose. Additionally, chitin is not as abundant in nature as cellulose.
What are examples of a natural polymer?
cellulose Starch (amylose and amylopectin) proteins silk, spider webs are also poly-peptides (proteins) and are natural polymers polyhydroxyalkanoates (natural polyesters made by bacteria as food reserves) deoxyribonucleic acid (DNA) Natural Rubber Many polysacharides: Xanthan gum, B-Glucans, chitosan (from crab, shrimp, lobster shells) Enkephaline
Does fungi have cell walls that contain chitin?
No, it is important to differentiate between plants and fungi. Plant cell walls contain a carbohydrate polymer called cellulose. Fungi cell walls contain a different type of carbohydrate polymer called chitin. Chitin is harder than cellulose.
What are some examples of natural polymers and synthetic polymers?
Natural polymer: shellac, amber, natural rubber, cellulose Synthetic polymers: synthetic rubber, Bakelite, neoprene, nylon, PVC, polystyrene, polyethylene, polypropylene, silicone, etc.
What are some polysaccharides?
Cellulose; starch; chitin
What are these glucose polymers called?
Starch
