What is the term used for strings of monosaccharides?

The term used for strings of monosaccharides is carbohydrates. Carbohydrates are organic compounds that include sugars, starches, and fibers, and they are essential for providing energy to the body. Monosaccharides like glucose and fructose are the simplest forms of carbohydrates, and when they link together, they form oligosaccharides and polysaccharides.

While fibers and roughage refer specifically to certain types of carbohydrates that the body cannot digest, they are not the general term for all strings of monosaccharides. Starches are a specific type of polysaccharide that serve as energy storage in plants, but they fit under the broader category of carbohydrates. Therefore, carbohydrates is the most encompassing and correct answer reflecting the nature of monosaccharides linked together.
