Across
  1. 4. the property of floating on the surface of a liquid)
  2. 5. property of a substance that repels water.
  3. 8. a chain of amino acids joined together by peptide bonds.
  4. 9. largest class of lipids, and function as long-term energy storage; formed by condensation from three fatty acids and one glycerol.
  5. 12. a significant excess in body fat (BMI>30) caused by increased intake of energy or decreased energy expenditure
  6. 13. totality of proteins expressed within a cell, tissue, or organism at a certain time.
  7. 14. is a disaccharide comprising of glucose and galactose; it is a source of energy (the main one for newborns).
  8. 16. is the synthesis of complex molecules to form simpler molecules including the formation of macromolecules from monomers by condensation reactions.
  9. 17. are polysaccharides comprised of many monosaccharide monomers.
  10. 19. fatty acids that are saturated do not contain double bonds between carbon atoms.
  11. 20. is a starch with a helical shape found in plants; it can form 1-4 bonds.
Down
  1. 1. the active site of an enzyme is very specific to its substrate as it has a very precise shape, due to which enzymes can only catalyze certain reactions where the substrates fit the active site.
  2. 2. a chemical bond that forms between two monosaccharides.
  3. 3. occurs when polymers are broken down by the chemical addition of water molecules to form monomers (breaking of glycosidic bond).
  4. 6. is an energy storage polysaccharide formed in the liver of animals; it is composed of a-glucose subunits linked together by both 1-4 linkages and 1-6 linkages.
  5. 7. is a structural change in a protein that results in the loss of its biological properties; if the shape is changed, its activity will also alter.
  6. 10. a disaccharide produced mainly in plants.
  7. 11. refers to any process that living organisms use to maintain stable conditions necessary for survival.
  8. 15. a liquid in which substances (solutes) are dissolved forming a solution.
  9. 18. a polysaccharide found in plants comprising of glucose monomers joined in alpha 1,4 linkages.
