Saccharides are the monomers which are combined to form carbohydrates. 
Depending on the type of carbohydrate, the monomer components can be monosaccharides, disaccharide, polysaccharide, etc.
E.g: Sucrose is a carbohydrate (specifically a dissacharide) that is made of glucose and fructose monosaccharides.
Another example is cellulose, which is a carbohydrate (specifically a polysaccharide) that is made of beta glucose monosaccharide components combined together.
        
             
        
        
        
This is possible because proteins are created from different combinations of amino-acids. While we only have 20 different kinds of aminoacids, these 20 kinds can create thousands of combinations that we can observe in our bodies and bodies of other mammals as well as other organisms.
