Final answer:
Polysaccharides are composed of long chains of monosaccharides linked together. The constituents of polysaccharides are primarily D-glucose. Polysaccharides do not directly contain amino acids, but can be associated with proteins to form glycoproteins.
Step-by-step explanation:
Polysaccharides are long polymers composed of monosaccharides linked by glycosidic linkages. The constituents of polysaccharides are primarily D-glucose, except for chitin, which is composed of a modified form of glucose. Some examples of polysaccharides are starch, glycogen, cellulose, and chitin.
In terms of amino acids, polysaccharides do not directly contain amino acids. Amino acids are the building blocks of proteins, which are a separate class of macromolecules. However, polysaccharides can be associated with proteins to form glycoproteins, which contain both carbohydrates and proteins.
