Proteins are structurally complex with diverse sequences due to 20 different amino acids, leading to a vast number of unique proteins, unlike the repeating units in polysaccharides.
Proteins are much more structurally complex than polysaccharides. Proteins are composed of 20 different amino acids that can be arranged in countless unique sequences, leading to an enormous diversity of possible proteins. The interaction of amino acids within a protein chain causes it to fold into complex three-dimensional shapes, resulting in many different 'shapes' on the protein compared to the repeating units in polysaccharides.
