2.1.2 Biological molecules Flashcards
1
Q
how does hydrogen boning occur between water molecules
A
- electrons are shared unevenly
- oxygen is more electronegative thus attract more electrons making it slightly negative an the hydrogen slightly positive
- oxygen and hydrogen attracted to each other on different molecules(of water)

A
disaccharide (two glucose monosaccharide formed together via glyosidic bond)
