Unformatted text preview: 3. 2 Macromolecules are polymers , built from monomer S . A POLYMER is a long molecule consisting of many Similar /identical building blocks linked by covalent bonds The repcating units that serve as building blocks are Smaller molecules called MONOMERS The Synthesis + Breakdown of Polymers - ENZYMES Speed up chemical reactions . Monomers are connected by a reaction in which 2 molecules are covalently bonded to each other , with the loss of a water molecule is a DEHYDRATION REACTION o Polymers are disassembled to monomers by HYDROLYSIS comic is a process that is essentially the reverse of the dehydrat reachon 3.3 Carbohydrates serve as fuel + building material . CARBOHYDRATES include both sugars + polymers of sugars " monosaccharides /simple sugars are the simplest of carbohydrates . theres also disaccharides (double sugars ) and poly Sacchandes Sugars . MONOSACCHARIDES have molecular formulas that are Some mumtip of the unit CHz d ' examples : glucose (Co Hi20 )- it isthe most common fructose - different Structure than glucose . they are major nutrients for cells helps w/ cellular respiration and Synthesis of other organic moled . A DISACCHARIDE consists of- 2 monosaccharides jomed by a GLYCOSIDIC LINKAGE , a covalent bond furmed between 2 monosaccharides by a dehydrator reaction. . examples : Sucrose - most prevalent w /master Lan Polysaccharides lac nose - the sugar in milk . POLYSACCHARIDES are macromolecules , polymers wl a few hun to a few thousand monosaccharides joined by glycos dic linkagjes e serves as Storage metal or building material to protect cell...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
