GCE CIE BIOL - Formation and Breakage of Glycosidic Bonds
Chapter 2 Biological Molecules
2.2.c Describe the formation of a glycosidic bond by condensation, with reference both to polysaccharides and to disaccharides, including sucrose.
2.2.d Describe the breakage of glycosidic bonds in polysaccharides and disaccharides by hydrolysis, with reference to the non-reducing sugar test.
FORMATION OF DISACCHARIDES AND POLYSACCHARIDES:
The above image shows the formation of disaccharides via condensation, and also demonstrates that hydrolysis separates disaccharides into two monosaccharides.
BREAKAGE OF DISACCHARIDES AND POLYSACCHARIDES:
⚠️🧠 For your GCE CIE Biology exam remember:Condensation joins molecules; hydrolysis splits molecules.
Woooo! See you! 😊
