carbon, hydrogen, oxygen.
2 of 15
what are the components of lipids?
Carbon, hydrogen, oxygen and phosphorus
3 of 15
what are the components of protiens?
carbon, hydrogen, oxygen and nitrogen
4 of 15
what are the components of nucleic acids?
carbon, hydrogen, oxygen, nitrogen and phosphorus
5 of 15
What are the 2 types of chemical bonds?
Covalent bonds and hydrogen bonds
6 of 15
what are covalent bonds like?
strong, hold together all organic molecules, cannot be made or broken in the temperature of living cells, they need enzymes to make or break bonds.
7 of 15
What are hydrogen bonds like?
very weak, formed between an atom with a slight negative charge and another with a slight positive charge, can easily be made or broken wwithout the use of enzymes.
8 of 15

glucose, fructose and galactose
10 of 15
what is a disaccharide?
formed when 2 monasaccharides are joined.
