formed when electrons are shared between atoms. They are very strong and form new molecules.
1 of 12
Carbohydrates
Make up a group of molecules including carbon, hydrogen and oxygen in the ratio Cn(H2O)n
2 of 12
Polysaccharides
Polymers of monosaccharides, consisting of hundreds to thousands of monosaccharide monomers bonded together to form a single large molecule.
3 of 12
Cellulose
Carbohydrate polymer made by bonding many beta-glucose molecules together in long chains.
4 of 12
Amino acids
The monomers of all proteins. They all have the same basic structure. There are 20 different amino acids involved in protein synthesis and differ only by the R-group bonded to the central carbon.
5 of 12
Primary structure of a protein
Sequence of amino acids that make up a protein.
6 of 12
Secondary structure of a protein
Beta pleated sheets or alpha helix.
7 of 12
Tertiary structure of a protein
3D shape of the final protein molecule.
8 of 12
Haemoglobin
A globular transport protein that transports oxygen around they body.
9 of 12
Collagen
A fibrous structual protein that support and give cells structure.
10 of 12
Lipids
Group of chemicals that dissollve in organic solvents, such as alcohol, but not in water. They include fatty acids, triglycerides and cholesterol.
11 of 12
Hydrogen bond
A weak interaction that occurs when molecules contain a slightly negatively charged atom bonded to a slightly positively charged hydrogen.
