Document Summary

Carbohydrates (cid:120) this chapter discusses the fundamental chemistry and properties of carbohydrates, emphasizing on monosaccharides. Carbohydrates (cid:121) 2 (cid:120) they are made primarily by plants via photosynthesis. Hence, they serve as a mechanism of energy storage. Light energy + co2 + h2o (cid:198)(cid:198) carbohydrates + o2 (cid:120) carbohydrates also have structural roles, such as cellulose and chitin. (cid:120) they are also components of some drugs, such as salicin (willow bark) and adriamycin (streptomyces achromogenes). Carbohydrates (cid:121) 3 (cid:120) carbohydrates are found as components of not only small biomolecules, but also in large, high-molecular-weight biopolymers. Carbohydrates (cid:121) 4 (cid:120) simple sugars have the empirical of a hydrated carbon, c(h2o), so they have the molecular formula cn(h2o)n or cnh2non. The former term is usually reserved for chains containing many monosaccharides (typically > 10); polysaccharides are usually naturally isolated because they are difficult to make in the lab: classification.
