Hydrolysis and dehydration synthesis Standard 4 key idea 3 performance indicator 1.2 major understanding 1.2h
We have learned about carbohydrates, protein, and lipids. We obtain these nutrients from food. • How do we digest these nutrients? How do we break them down? http://livefitwithstephanie.com/cornerstonereminder/
Hydrolysis • Splitting with water: Examples Starch + N water -N glucose Maltose + water 2 glucose Lipid + 2 water glycerol + 3 fatty acids Protein + N water N amino acids
Maltose + water 2 glucose http://cnx.org/content/m44397/latest/
Lipid + water glycerol and 3 fatty acids http://ww2.mackblackwell.org/web/research/ALL_RESEARCH_PROJECTS/2000s/2092/MBTC-2092.htm
Protein + water amino acids http://course1.winona.edu/sberg/ChemStructures/Hydrolys.gif
Group activity • Using models of macromolecules, simulate the process of hydrolysis.
Dehydration synthesis: putting together by taking out water (opposite of hydrolysis) • combining monomers by removing atoms needed to form a molecule of water Examples: glucose + glucose maltose
Glucose+ glucose maltose + water http://cnx.org/content/m44397/latest/
Glycerol + fatty acids triglyceride + water http://science.halleyhosting.com/sci/ibbio/chem/notes/chpt3/triglyceride.htm
Amino acid + amino acid dipeptide or protein http://quintenrene.wordpress.com/
