Verified step by step guidance1
Understand the context: The question is asking about a polysaccharide commonly consumed in the diet.
Identify the options: The options given are chitin, glucose, lactose, ribose, and starch.
Clarify the terms: Recognize that chitin is a structural polysaccharide found in the exoskeletons of arthropods, not typically consumed in a regular diet. Glucose and ribose are monosaccharides, not polysaccharides. Lactose is a disaccharide, not a polysaccharide.
Focus on starch: Starch is a polysaccharide that is a major component of many foods such as potatoes, rice, and bread, making it a common part of the human diet.
Conclude: Based on the analysis, starch is the polysaccharide most likely to have been consumed recently.
