PROTEIN
PROTEIN FUNCTION
STRUCTURE
:star:Collagen: A component of the connective tissue of animals (most abundant
protein in mammals)
:star: Spider silk: A fiber spun by spiders and used to make webs (by weight, is
stronger than kevlar and steel)
HORMONE
:star: Insulin : Protein produced by the pancreas and triggers a reduction in blood glucose levels.
:star: Glucagon : Protein produced by the pancreas that triggers an increase in blood glucose levels.
IMMUNITY
:star: Immunoglobulins : Antibodies produced by plasma cells that are capable of targeting specific antigens
TRANSPORT
:star: Haemoglobin : A protein found in red blood cells that is responsible for the transport of oxygen.
:star: Cytochrome : A group of proteins located in the mitochondria and involved in the electron transport chain.
SENSATION
:star: Rhodopsin : A pigment in the photoreceptor cells of the retina that is responsible for the detection of light.
MOVEMENT
:star: Actin : Thin filamen involved in the contraction of muscle fibres
:star: Myosin : Thick filaments involved in the contraction of muscle fibres

FOUR LEVELS OF PROTEIN
STRUCTURE
:green_cross: The four levels of protein structure are distinguished from one another by the degree of complexity in the polypeptide chain. A single protein molecule may contain one or more of the protein structure types: primary, secondary, tertiary, and quaternary structure.

PROTEIN DENATURATION
:red_flag: Each protein has its own unique sequence and shape held together by chemical
interactions.
:red_flag: Denaturation is a structural change in a protein that results in the loss
(usually permanent) of its biological
:red_flag: Denaturation of proteins can usually be caused by two key conditions
temperature and pH
:check: One of the most abundant organic molecules in living systems
:check: Proteins have different shapes and molecular weights
:check: Protein shape is critical to its function
:check: Changes in temperature, pH and exposure to chemicals may lead to permanent changes in the shape of the protein
:check: Leading to a loss of function or denaturation
:check: Amino acids are the monomers that make up proteins
