Step 1: Concept
Biopolymers are held together by specific covalent bonds.
Step 2: Meaning
A glycosidic bond is a type of covalent bond that joins a carbohydrate (sugar) molecule to another group.
Step 3: Analysis
In polysaccharides like starch or cellulose, individual monosaccharide units are linked together via these glycosidic bonds.
Step 4: Conclusion
Therefore, glycosidic linkages are characteristic of sugar/carbohydrate polymers.
