Biochemistry

1. Site folds on the enzyme that allows the substrate to fit and attach
6. smaller molecules that build carbon compounds
7. large polymers
8. long fatty acid chain joined to a long alcohol chain
11. monomer of a carbohydrate; simple sugar
12. two monosaccharides can combine in a condensation reaction to form these
14. Acids make up most lipids;long carbon chain with a carboxyl group at one end
16. these serve as a source of energy and are used as structural materials; they exist as monosaccharides, disaccharides, or polysaccharides
19. main source of energy for cells
20. group a cluster of atoms that influences the characteristics of the molecules they compose
22. formed by the linkage of monomers called amino acids
24. compounds that have a single chemical formula but different structural forms
25. a molecule that consists of repeated linked units

2. lipids that contain three molecules of fatty acid joined to one molecule of glycerol
3. a complex molecule composed of three or more monosaccharides
4. a process where living organisms break down complex polymers; reverse of condensation
5. found in fruits and is the sweetest of the monosaccharides
9. adenosine triphosphate
10. the reactant being catalyzed
13. also called dehydration synthesis; in this chemical reaction, each time a monomer is added to a polymer, a water molecule is released
15. Acids large, complex organic molecules that store genetic information and transfer information within the cell
17. found in milk
18. protein molecules that act as biological catalysts
21. these large organic molecules are not soluble in water and they store energy for later use, form membranes, and build cholesterol
23. compounds compounds that contain mostly carbon atoms
