What type of nutrient is starch?

Question

BlackTom AI · Accepted Answer

When considering what starch is, we first place it in the category of carbohydrates produced by plants. 
Option 1: complex carbohydrate. This is the correct characterization because starch is a polysaccharide, meaning it is a long chain of glucose units linked together. It is a storage form of glucose in plants. 
Option 2: simple carbohydrate. This would refer to monosaccharides or disaccharides like glucose, fructose, or sucrose, which are not the polymer form of starch. Starch is not a simple sugar, so this label is inaccurate. 
Option 3: fiber. Dietary fiber consists of indigestible carbohydrate components that are not broken down by human enzymes. Starch, in contrast, is digestible by human amylase and provides energy, making it not fiber. 
Option 4: gluten. Gluten is a protein complex found in wheat and other grains, not a carbohydrate. Therefore, referring to starch as gluten is incorrect. 
Option 5: monosaccharide. A monosaccharide is a single sugar molecule like glucose. Starch is built from many glucose units, forming a polysaccharide, so labeling it a monosaccharide is incorrect.
