Answer:
True
Explanation:
Long carbohydrates or polysaccharides are made of joining carbohydrates or sugar units. Monomer of carbohydrates are glucose. In starch, two glucose units are joined by α 1,4 linkages. In starch, linear units and branched units both are present.
Linear units are called amylose and branched units are called amylopectin.
Branched units linked to linear unit by 1,6-alpha glycosidic bonds.
Therefore, its can be said that long carbohydrate chains are really just polymers of simple ones. So, the given statement is true.
