Unformatted text preview: in Glucose a monosaccharide How Many? Carbon = 6 Hydrogen = 12 Oxygen = 6 2:1 H:O Starch is made of many glucose molecules bonded together by dehydration synthesis Starch Glucose Go to Section: Dehydration Synthesis • dehydration synthesis – Synthesis means “putting together” – dehydration means “removing water” – “putting together molecules by removing water” • By removing an OH group from one molecule and a H from another you open up a site for the two molecules to bond together. • Cells build larger molecules from smaller molecules by this process • It is a major part of metabolism. Hydrolysis • Process that breaks apart large molecules into smaller parts • Hydrolysis is the opposite of Dehydration Synthesis • Bonds are broken in a large molecule and water provides an OH and a H to fill the open bonding sites • Hydrolysis is one part of metabolism in an organism Dipeptide + Water Amino Acid + Amino Acid + + Maltose + Water Glucose + Glucose Lipid + 3Water 1 Glycerol + 3 Fatty Acids 3 + + 3 Dehydration Synthesis H2O was removed to open a bonding site for the two monosaccharide to bond together Dehydration Synthesis H2O is a product Hydrolysis Dehydration Synthesis Lipids • Contain carbon, hydrogen and oxygen – ratio of hydrogen to oxygen is much greater than 2:1 and changes from one lipid to another – examples: fats, oils and waxes • Function • Four parts – one glycerol molecule – th...
