Types of Proteins
- Globular
- Round and compact
- Hydrophilic R groups are pushed to the
outside of the molecule, due to
interactions in the tertiary structure
- Soluble
- Easily transported in fluids
- Easily transported in fluids
- Soluble
- Haemoglobin
- Carrier oxygen around the
body in red blood cells
- Conjugated protein
- "A protein with a non-protein group"
- Non-protein part is the prosthetic group
- Each of the four polypeptide chains
has a prosthetic group called haem
- Haem group contains an iron
which bonds with oxygen
- Haem group contains an iron
which bonds with oxygen
- Each of the four polypeptide chains
has a prosthetic group called haem
- Non-protein part is the prosthetic group
- "A protein with a non-protein group"
- Carrier oxygen around the
body in red blood cells
- Insulin
- Hormone secreted by Pancreas
- Regulate blood glucose levels
- Solubility is important, as it can
be transported in the blood
- 2 polypeptide
chains connected by
disulfide bonds
- Hormone secreted by Pancreas
- Amylase
- Enzyme that catalyses the breakdown
of starch in the digestive system
- Single chain of amino acids
- Secondary structure contains both
A-helix and B-pleated sheets
- Most enzymes are globular proteins
- Enzyme that catalyses the breakdown
of starch in the digestive system
- Round and compact
- Fibrous
- Insoluble and Strong
- Structural proteins that are fairly unreactive
- Structural proteins that are fairly unreactive
- Collagen
- Found in animal connective
tissues, such as bone and skin
- Strong Molecule
- Minerals can bind to the
protein to increase its rigidity
- Quaternary Structure
- Found in animal connective
tissues, such as bone and skin
- Keratin
- Found in external structures
of animals eg: nails
- It can either be flexible (skin)
or hard and tough (nail)
- Found in external structures
of animals eg: nails
- Elastin
- Found in elastic connective tissue
- It is elastic and allows tissue to return to its
original shape if it has been stretched
- Found in elastic connective tissue
- Insoluble and Strong
