Here in this example question, it says, classify each carbohydrate as monosaccharide, disaccharide, oligosaccharide, or polysaccharide. Now, in the first one, it says it's a water-soluble fiber containing 3 carbohydrate units. So remember, this is in line with an oligosaccharide. An oligosaccharide is composed of 3 to 10 carbohydrate units or monosaccharide units. Next, this carbohydrate is found in animal tissue and is highly branched. We talked about branching when it came to the polysaccharide class of carbohydrates.
Next, it says, formed by the combination of 1 glucose and 1 fructose unit. Ose, ose. These are 2 sugar units. There are two of them, so this would have to be a disaccharide. And then finally here it says, produced by hydrolysis of sugar naturally found in milk. Alright. So we have the hydrolysis of sugar naturally found in milk. So here, this would have to be a monosaccharide by process of elimination. It's the only one left out of all our options. So here we'd say oligosaccharide, polysaccharide, disaccharide, and finally, monosaccharide as the answer to these four statements.
