Handout #4 Bio2960-10 Principles in Biology I Lecture 2 (Jan 22, 10): Carbohydrates Reading assignment: Sadava et al: Chapt 3, p. 38-42 (section 3.1) & 49-54 (section 3.3) Outlines: I. Review of alcohol aldehyde carboxylic acid scheme A primary alcohol can be oxidized to form an aldehyde, and then further oxidized to a carboxylic acid. A secondary alcohol can be oxidized to form a ketone. C C OH C C O H C C O OH C C C OH C C C O An easy example to know and to remember: Ethyl alcohol (ethanol) acetaldehyde acetate (acetyl-) II. Basic features of macromolecules: modular and formed by a condensation process (degraded by hydrolysis to monomers) III. Carbohydrates are built from monosaccharides (eg. Glucose)—to form disaccharides (eg. sucrose), oligosaccharides and polysaccharides (eg. Starch)

    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.
