Document Summary

Chapter 5- the structure and function of large biological molecules. Polymers- long molecules (macromolecule) consisting of many similar building blocks linked by covalent bonds (with loss of water molecule)- lipids don"t have polymers. Monomers- the repeating unit, smaller units of polymer. Breaking and making polymers are facilitated by enzymes- macromolecules that speed up chemical reaction. Hydrolysis- dissembles polymers into monomers- reverse of: break polymers by adding water- h from water attaching to one monomer and hydroxyl group attaching to adjacent monomer. Huge variation of polymers- each cell has so many even: digestion is an example, 40 to 50 monomers in common monomers, so arrangement matters (like letters in words) Carbohydrates- include sugars and polymers of sugars which more complex carbohydrates are made. Monosaccharides- simple sugars (end in ose), monomers from: usually have molecular formula that is multiple of ch2o. Glucose (c6h12o6)- trademarks of a sugar in the makeup with carbonyl group (c=o) and multiple hydroxyl groups (-oh)
