Protein Functions and Structure Flashcards
Catalysis
Enzymes Proteases ATPases- hydrolyse ATP ATP Kinases - add phosphate group Nucleases - breaks nucleic acids
Movement
Muscle proteins
Myosin, actin & flagella
Cellular Control
Hormones - insulin, growth hormone, sex hormones
Receptors - ligand recognition to induce response
Transport
Respiratory proteins - haemoglobin
Cytochromes - electron transport
Storage - stores iron in toxic and non toxic form
Structural
Skin, Bones - collagen
Hair, nails - keratin
Immune System
Defence - against toxins and pathogens
Oxytocin function
Contracts uterus and helps lactation
Synthetic version can be used to induce labour
Somatostatin function
Inhibits release of growth hormones can be used to treat ulcers
Melittin function
Bee venom can be used to treat rheumatoid arthritis
Calitonin function
Regulates calcium and used to treat osteoporosis
Beta amyloid
Causes alzhiemers and is present in amyloid plaques in the brain
