Document Summary
Chapter 2 cell chemistry and biosynthesis y hydrophilic compounds are those that are water loving : such as those that can form hydrogen bonds, or those that carry a positive or negative charge, dissolve in water. sugars, dna,rna, most proteins are all hydrophilic y hydrophobic compounds are those that are water-fearing : uncharged, few or no hydrogen bonds, not dissolvable in water. Ionic bonds: very strong in the absence of water, water dissociated the charged atoms y y hydrogen bonds: ok-strong bonds formed between hydrogen and either oxygen, nitrogen and fluorine. sugars: y the simplest form of sugars are called monosaccharides: common formula: (ch2o)n, where n = 3,4,5,6,7, or 8 y glucose is (ch2o)6 or c6h12o6, glucose is used widely by animals and plants for energy y. It is used as the polysaccharides with the subunits of glucose, glycogen in animals and starch in plants y these are referred to as carbohydrates because of their formula.
