Although I am more a bacteria person I know that plant DNA is notoriously hard to purify correctly as the large number of polysaccharides and multiples organic acids can be co-purified with the DNA. I am currently working with algae samples, and finding a purification method ...

... can also be alosteric regulators (think of fructose 1,6-bisphosphate in glycolysis) and so can disaccharides (think of lactose in the lac operon). Polysaccharides have a structural role in the cell wall of plants (cellulose) and fungi (poly-N-acetylglucosamine), they are important for cell adhesion ...

... of a particular ion. Other polar molecules pass through other passage proteins (pumps/permeases). Macromolecules (proteins, polynucleotides, polysaccharides) are an exception - they cannot pass through the cell membrane, simply because they are too big. Generally macromolecules pass through ...
