At a conference, the speaker's grand finale was sautéing mealworms (insect larvae) in butter and serving them to the audience. They were crunchy (like popcorn hulls) because their exoskeletons contain the polysaccharide ______________

1.linoleic acid
2.cellulose
3.chitin
4.collagen
5.glycogen

Answer 1

Answer:

3) Chitin

Explanation:

Most insectcs are arthropods which are covered with a hard exoskeleton that helps in their movement and also provide protection to soft tissue. This exoskeleton is made up of protein (sclerotin) and polysaccharide called chitin. Chitin is also found in cell wall of fungi.

Chitin is most abundandant aminopolysaccharide in nature and second most abundant carbohydrate on earth. Chemicaly chitin  is known as poly (β-(1-4)-N-acetyl-D-glucosamine. Chitin is flexible, transparent and, as u tasted, crunchy subatance.
