Document Summary
Carbohydrates include simple sugars & polymers of sugars. Energy is stored in chemical bonds between carbon and other atoms. Disaccharides - two monosaccharides joined by a condensation reaction. Monosaccharides are classified by the number of carbons in the backbone. Glucose & other 6 carbon sugars are hexoses. Minor structural changes result in different sugars glucose vs. galactose. Minor rearrangements of atoms can result in the formation of a ring structure. Joined by condensation reactions (dehydration reactions) review!! Maltose -- > glucose + glucose from hydrolysis of starch. Sucrose -- > glucose + fructose cane sugar, beet sugar, pineapple table sugar . Lactose -- > glucose + galactose milk sugar - 7. 5% of milk broken down by enzyme - lactase lactose intolerance - no lactase cramps, diarrhea. Polymers of monomer sugars hundreds to thousands of monosaccharides. Structure & properties depend on: kinds of sugar the way that they are joined.
