Verified step by step guidance

Understand the context: The question is asking about a polysaccharide that is a structural component in lobsters and insects.

Recall the structure and function of polysaccharides: Polysaccharides are long chains of monosaccharides linked by glycosidic bonds, and they serve various functions such as energy storage and structural support.

Identify the structural polysaccharide: Chitin is known for its role in forming the exoskeletons of arthropods, including lobsters and insects, providing strength and protection.

Differentiate chitin from other polysaccharides: Unlike cellulose, starch, and glycogen, chitin contains nitrogen, which is a key component in its structure, making it suitable for forming hard exoskeletons.

Conclude with the correct choice: Based on the function and composition, chitin is the polysaccharide that fits the description of being an important structural component in lobsters and insects.
