Document Summary

In dna, complementary base pairs are held together by hydrogen bonds. Dna can store and transmit biological information. Dna"s primary structure serves as a template for the synthesis of a complementary strand. Use one strand as a template and a new one will form that"s complementary. N" can vary from 3 to over a thousand. Contain a carbonyl group (c=o), hydroxyl groups (o-h), and many carbon-hydrogen bonds (c-h) Complex carbs: long branched chains of monosaccharides. Distinct monosaccharides exist because so many aspects of their structure are variable. Aldose or ketose: placement of the carbonyl group. Sugars typically form ring structures in aqueous solutions. Polysaccharides, or complex carbs, are polymers of monosaccharides monomers. 2 sugars linked together form a disaccharide. Sugars are linked when a condensation reaction occurs between two hydroxyl groups. A covalent bond called a glycosidic linkage forms. The linkages can be broken by hydrolysis. Two monosaccharides linked by a dehydration synthesis reaction to form a glycosidic bond.
