摘要: Carbohydrates constitute the most abundant class of biomolecules on Earth. They are “global players” and indeed play many roles. store energy water. serve as metabolic intermediates. function stable, raw materials or intelligent, bioengineered products. even active in “social media”, that is, they mediate communication between cells information by molecular shaping. adopt more forms shapes than one can conceive 24 hours. exist small mono- oligo-saccharides, large highly complex polysaccharides, conjugation with, for example, proteins lipids, forming a kingdom glycoconjugates found every cell surface.
