Describe Nucleic Acids in terms of in Biomacromolecules
The special type of macromolecule that one would find in the acid insoluble fraction of any living tissue is the nucleic acids. These are polynucleotides. Together with polysaccharides and polypeptides these comprise the true macromolecular…
Explain Polysaccharides in Biomacromolecules
The acid insoluble pellet has polysaccharides (carbohydrates) as another class of macromolecules. Polysaccharides are long chains of sugars. They are threads (literally a cotton thread) containing different monosaccharides as building blocks. For example cellulose is…
