•An organic compound that is the body’s main source of energy.
•Chapter 15
Produced by green plants during photosynthesis.
The carbohydrate formed by photosynthesis is glucose
Glucose is the basic sugar molecule from which all other carbohydrates are built

Range of Sweetness
Caramelization – browning reaction that can occur with any kind of sugarHow to caramelize sugar – http://www.youtube.com/watch?v=HjqRzyZXwkA (1:38) http://www.youtube.com/watch?v=jMiXJE3eXN0 (5:45)
Solubility – dissolve in water easily because of the many hydroxyl groups
Crystallization – occurs when you add more sugar to a solvent than it can dissolve. http://www.youtube.com/watch?v=WQdXbf8huuQ&list=TLWk1HVncEGRk (7:23)
Must be broken down into sugar so they take longer to digest and will provide longer lasting energy
Amylose – molecules are linear: they’re long and narrow like a line
Amylopectin – have multiple branches, like the veins in a leaf
Cellulose is fiber that gives plants their structure.
45-65% of calories should come from carbohydrates
Most should come from complex carbohydrates
Lack of energy Uses protein as energy source Lack of vitamins, minerals, and fibers Not enough cushioning for the organs Central nervous system, kidneys, brain,
and muscles won’t function properly
Stored as excess fat More susceptible to heart disease
Simple carbohydrates Raises blood sugar levels
Whole grains Reduce risk of heart
disease minimize chances of
getting diabetes Oats
Slow down digestion Lowers cholesterol
Large amounts Makes you slow and sleepy
