Chapter 5: The structure and function of large Biological Molecules. The Molecules of bearing: Carbohydrates glucose & ribose Lipids Proteins Nucleic acids -macromolecules- carbohydrates, proteins, and nucleic acids 5.1 Macromolecules ar polymers, built from monomers chain like molecules called polymers: a believe molecule consisting of many similar/idential build blocks linked by covalent bonds (like a train with chains of cars) -Monomers- repeating units in the building blocks of a polymer. The synthesis and Breakdown of Polymers * Condensation/ desiccation) resolution: monomers connected by a reaction where two covalently bonded molecules bonded to from from each one one other(a) due to loss of urine molecule. * by removing water molecule to form new bond * When two monomers form a bond, one molecule provide (+H) and other provides (-OH) forming a polymer. thence facilitated by enzymes, specialized macromolecules that sp eed up chemical reactions. * hydrolysis: to bust using water; reverse of dehydration reaction: polymers are disassembled to monomers by adding water molecules to break a bond (digestion) The conversion of Polymers * Polymers constructed from 40-50 common monomers * KEY = ARRANGEMENT 5.

2: Carbohydrates serve as fuel and building material Carbohydrates: halt-go line and polymers of sugars -Monosaccharides: simple sugar - Disaccharides: double sugars (2 monosaccharides joined by a covalent bond) -Polysaccharides: many sugar building blocks Sugars Monosaccharides: Glucose (C6H12O6) How to banish sugar? Step 1: Location of the centuryyl group (C=O) each ald ose (aldehyde sugar) or ketose (ketone sugar! ) Ex:glucose = aldose Step 2: Size of hundred skeleton: 3-7 carbons long * sugars with 6 carbons ? hexoses Ex: glucose; fructose * sugars with 3 carbons ? trioses * sugars with 5 carbons ? pentoses Step 3: Spatial arrangement of their separate most asymmetric carbons: * In aqueous solutions,...If you want to get a full essay, order it on our website: OrderEssay.net
