PROTEINS
Globular
Soluble
spherical shape
tightly folded
hydrophilic group is inside
hydrophobic group(R group)is found inside
four polypeptide chains
has two alpha and two beta chains
any change in folding can cause sickle cell anaemia
haemoglobin is an example of globular protein
Fibrous
Insoluble
parallel polypeptide chains
long rope like fibres
high tensile strength
an example of fibrous protein is collagen
every third amino acid is glyceine
three polypeptide chains
Non identical polypeptides
