Proteins, Carbohydrates and Lipids
B1.7 The relationship between the structure, properties and function of proteins
-
key terms:
-
Amino Acid: A molecule with both an amino group and a carboxyl group. Amino acids are the small molecules (monomers) from which all proteins are made.
Protein: a polypeptide with a three-dimensional structure. It may contain more than one polypeptide chain.
Condensation reaction: a reaction between two small molecules to produce a larger molecule and water

B1.8 The relationship between the structure, properties and functions of carbohydrates
Monosaccharides
Glucose: 
-
-
As they are such large molecules, they are usually insoluble. This makes them good for storage and support.
Disaccharides
Maltose:
Disaccharides are formed by condensation reactions between two monosaccharides - the bond formed is a glyosidic bond
-
-
Polysaccharides
-
Starch:
-

B1.9 The relationship between the structure, properties and function of lipids
-
Lipids consist of two or three fatty acids, which are joined to a molecule of glycerol in condensation reactions.
