Chapter 3 Section 2: Biochemistry-Review

Compare the structure of monosaccharides, disaccharides, and polysaccharides. A monosaccharide is a monomer of carbohydrates. 2 monosaccharides can combine to form a double sugar, or a disaccharide. A polysaccharide is a complex molecule composed of 3 or more monosaccharides. How are proteins constructed from amino acids? Amino acids link together to to form proteins. How […]
