Middle of the molecule 3 of 25 A aldehyde is found ..............(where in a molecule)........? End of the molecule 4 of 25 What is a funtional group? A group of atoms responsible for the characteristic reactions of a particular compound. 5 of 25 Starch is a carbohydrate found in.......(what organism)............... Plants 6 of 25 Glycogen is a carbohydrate found in.............(what organism/s) Animals 7 of 25 (CH2O)n is the formula for which carbohydrate unit? Monosaccharides 8 of 25 When glucose changes from chain form to cyclical form which number carbons are attached to each other? Carbon 5 and carbon 2 9 of 25 When Fructose changes from chain form to cyclical form which number carbons are attached to each other? Carbon 5 and carbon 2 10 of 25 All monosaccharides which contain ketone groups are known as .......... Ketoses 11 of 25 All monosaccharides which contain aldehyde groups are known as.......... Aldoses 12 of 25 What reducing agent is commonly used in reducing sugars practicals? And what colour is produced? Benedict's Solution and Red 13 of 25 Give an example of a non reducing sugar? Sucrose 14 of 25 When an alpha glucose is joined to another alpha glucose what is the disaccharide formed? Maltose 15 of 25 What is the bond called when two monosaccharides are joined together? Glycosidic bond 16 of 25 In the formation of the disaccharide maltose what are the carbons that cause the glycosidic bond? Carbon 1 and carbon 4 17 of 25 In the formation of the disaccharide sucrose what are the carbons that cause the glycosidic bond? Carbon 1 and Carbon 2 18 of 25 When monosaccharides form long chains they become..............? Polysaccharides 19 of 25 Give three examples of Polysaccharides 1. Starch 2.Amylose 3.Cellulose 20 of 25 In starch and glycogen the carbon 1-4 linkage causes the a bent structure to form. This is ideal for .............. Storage 21 of 25 Out of amylose and glycogen name which is linear and which is branched in structure? Glycogen is branched, amylose is linear 22 of 25 In cellulose the carbon (beta) 1-4 linkages causes a linear structure to form. This is ideal for ............? Structural purposes 23 of 25 When a glycosidic bond is formed, what molecule is released?
