Document Summary
Macromolecules include: proteins, carbohydrates, lipids, nucleic acids (dna/rna) Fun fact: clownfish have the ability to live within the tentacles of sea anemone without being stung. Clownfish actually have a dense layer of sugar coating them and this sugar coating insulates them from the sea anemone"s stings. Gram-positive microbes have a very thick peptidoglycan layer as compared to the gram-negative counterparts: when gram-stained, gram-positive microbes appear purple and gram- negative microbes appear pink (from safranin) Is the study of the structure, biosynthesis (how organisms produce), biology, and evolution of saccharides: saccharides include sugar chains and glycans. Rapidly growing field in the natural sciences. Bacteria that dwells in feces especially from poultry. Antibiotics are effective against this bacteria: if untreated though, victims may become paralyzed or die, c. jejuni can induce guillain-barre syndrome. Need sugar in order to develop flagella. Protect bacteria from the environment and provide cell membrane structural support.
