2.6 Proteins
-
Fibrous proteins
-
-
-
Collagen
-
-
Found in skin, tendons, cartilage, bones, blood vessels
3 polypeptide chains
Wound around each other, forming three-stranded 'rope'
-
-
Neighbouring collagen molecules form covalent bonds between R groups, holding collagen molecules together in 'fibrils'
-
Amino acids
-NH2, -CH + R group, -COOH
-
-
Primary structure
-
-
Amino end = beginning, acid end = end
Globular proteins
-
Hydrophilic R groups on outside, hydrophobic groups on inside (makes molecule soluble)
Haemoglobin
-
4 polypeptide chains
2 beta chains, made of beta globin
2 alpha chains, made of alpha globin
