Front 9

peptide bond

Back 9

bond together amino acids, formed with a dehydration reaction

Front 10

monomer

Back 10

a molecule that may bind chemically to other molecules to form a polymer

(H20 could be a monomer, when combined with other H20 it's a polymer).

Front 11

polypeptide

Back 11

very long chain of amino acids

Front 12

peptide

Back 12

a chain of two or more amino acids

Front 13

amylase

Back 13

enzyme that speeds the breakdown of starch into sugars

add to starch to make maltose

Front 14

Back 14

contains one glycerol and three fatty acids

Front 15

starch

Back 15

polymer that contains a large chain of glucoses (the monomers)
