Ch. 5 Macromolecules Polymer- a long molecule consisting of many similar or identical building blocks called monomers linked by covalent bonds. i.e. carbohydrates, proteins, & nucleic acid Condensation(dehydration) reaction – when two monomers are bonded to each other through the loss of a water molecule –OH from one and –H from another. Hydrolysis reaction – breaking of a polymer by adding water catalyst are enzymes. 5.2 Carbohydrates serve as fuel and building block 1. Sugars and polymers of sugars a. Monosaccharides- simplest/single sugars i. Molecular formula = generally some multiple form of CH 2 O b. Disaccharides – double sugars formed by condensation reaction and joined by a glycosidic bond. i. i.e maltose(gluc+gluc), sucrose(gluc+fruc), lactose(gluc+galact) c. Polysaccharides(macromolecules)- many monosacaccharides together i. Provide: storage material, provide sugar for cells, building block of structures that protect the cell/organism.

    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.
