Carbohydrates Compounds made of Carbon, Hydrogen, Oxygen - Main source of energy for living things – quick energy, 4 cal/g -The breakdown of sugars, supplies immediate energy for cell activities - Body uses this energy 1 st Plants, some animals, and other organisms can use carbohydrates for structural purposes

Simple Sugars Monosaccharide = single sugar molecules, s mallest Glucose = energy for cells, produced by plants Galactose = component of milk Fructose = found in many fruits - Easy for cells for break apart = energy Sucrose

Double Sugars Disaccharides – when 2 monosaccharides are put together Dehydration Synthesis– forming a polymer by putting a monomer + monomer together & water is removed Examples: - sucrose = glucose + fructose (table sugar) - lactose = glucose + galactose

Complex Carbohydrates Polysaccharides = large macromolecules formed by monosaccharides Used in 2 ways: 1. Storage: - Starch – in plants – Potato - Glycogen – in animals – stores excess sugar until your blood sugar is low then is broken down into glucose and released into blood - glycogen also stored in muscles, supplies the energy for muscle contraction

    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.
