Hi Meri, here's a little info. The monomers of proteins are the amino acids, while the monomers of polysaccharides such as starch are the monosaccharides or simple sugars. In both cases, the monmers link together to form long chains, but in polysaccharides, branched chains also occur. Below are a couple of links that introduce these two subjects. Big subject... lots of good websites out there! Steve |
