Across3. Lactose is a disaccharide that consists of galactose and glucose molecules. Lactose makes up around 2-8% of the solids in milk. The name comes from the Latin word for milk plus the -ose ending used to name sugars. Lactose is found in milk products. (7)
4. The univalent radical COOH characteristic of all organic acids. (8)
7. A macromolecule is a molecule with a large number of atoms. The word is usually used only when describing polymers molecules which are made up of smaller molecules called monomers. (13)
9. Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals and fungi. The polysaccharide structure represents the main storage form of glucose in the body. (8)
11. Hydrolysis is a chemical reaction or process in which a chemical compound reacts with water. This is the type of reaction that is used to break down polymers into many smaller units. In this reaction water is always added to the chemical compound. (10,8)
12. Nucleic acids are large molecules where genetic information is stored. There are two types of nucleic acids: deoxyribonucleic acid better known as DNA and ribonucleic acid better known as RNA. The nucleic acids are made of nucleotides. A nucleotide is made of a nitrogenous base sugar with five carbon atoms and a phosphate group (7,4)
13. A carbonyl is the group C=O in a molecule. (8)
15. any of a large group of organic compounds including sugars such as sucrose and polysaccharides such as cellulose glycogen and starch that contain carbon hydrogen and oxygen with the general formula C m (H 2 O) n : an important source of food and energy for animals (12)
16. "Fructose is a simple sugar (monosaccharide) found in many foods. It is also one of the three most important blood sugars the other two being glucose and galactose. Honey, tree fruits, berries, melons and some root vegetables such as beets, sweet potatoes, parsnips and onions contain fructose usually with sucrose and glucose. (8)
17. An isomer in chemistry is a chemical that has the same molecular formula as another but it has a different arrangement of atoms in space. Different isomers have different chemical properties (that is they may look or smell or taste different from each other). (6)
18. is a monosaccharide sugar that is less sweet than glucose and fructose (9)
19. A tough semi-transparent substance that is the main component of the exoskeletons of arthropods such as the shells of crustaceans and the outer coverings of insects. Chitin is also found in the cell walls of certain fungi and algae. Chemically it is a nitrogenous polysaccharide (a carbohydrate). (6)
20. any of a class of compounds containing only hydrogen and carbon as an alkane methane CH4 an alkene ethylene C2H4 an alkyne acetylene C2H2 or an aromatic compound benzene C6H6. (11)

Down1. aka malt sugar is a disaccharide formed from two units of glucose during a condensation reaction.________ is the disaccharide produced when amylase breaks down starch. It is found in germinating seeds as they break down their starch stores to use for food which is why it was named after malt. (7)
2. A carbohydrate that is a polymer composed of glucose units and that is the main component of the cell walls of most plants. It is insoluble in water and is used to make paper cellophane textiles explosives and other products. (9)
5. An Oligosaccharide is a polymer made of a few different simple sugars. Oligosaccharides are carbohydrates. (15)
6. the sucrose obtained from sugar cane which is identical to that obtained from sugar beet (4,5)
8. A condensation reaction is a chemical reaction in which two molecules combine to form a larger molecule together with the loss of a small molecule. (12,8)
10. a white crystalline monosaccharide sugar that has several optically active forms the most abundant being dextrose: a major energy source in metabolism. Formula: C6H12O 6 (7)
14. a soluble gummy substance obtained by hydrolysis of starch used as a thickening agent and in adhesives and dietary supplements (7)
