what is the actove chemical binding sote for chitin?
Homework Answers
The chtin binding site is a chitin binding domain or protein.
The chitin is a polysaccharide composed of 
-linked D-glucosamine residues. Most of these residues are
N-acetylated. The chitin binding protein domain is composed of
30-43 amino acid residues and mostly contain conserved glycine and
cysteines residues. The conserved cysteines form disulfide bonds.
Chitin-binding domains are usually found in plant, fungal and
bacterial proteins.

The polysaccharide chitin was first discovered about two hundred years ago by Henri Braconnot, when researching the composition and nutritional value of mushrooms. Since then, chitin has been found to play an important structural role in fungi, crustaceans and insects. Although chitin is not produced by humans, somewhat surprisingly the enzyme chitinase that breaks down chitin has been found in certain human tissues. Suggest an explanation for this situation guided by the following questions: a. What is about the molecular...

The horsefly Hybomitra lasiophthalma has a cuticle that is made up of a layer of chitin 89 nm think with an index of refraction of 1.73. This layer is on top of chitin with a smaller index of refraction (1.40). When light shines on the cuticle with an angle of incidence of 0o, what color will the cuticle appear? You may assume that the horsefly is in air. Explain/show your work. *Color wavelength (nm) Purple 380-450 blue 450-495 green 495-570...
