The purpose of our project is to determine if there are any
significant differences in protein size between freshwater fish and saltwater
fish.
From previous studies, we know that salinity content can
affect protein activity in fish blood (Peyghan et al), and to expand on this
subject, we decided to inspect whether salinity content can also influence fish
muscle protein. Proteins are chains of amino acids linked together to form primary,
secondary, tertiary or quaternary structures. There are certain factors that
can affect protein structures, such as temperature and pH level. In our case,
we inferred that saltwater fish and freshwater fish must have evolved different
structures of proteins in various sizes to adapt to the salinity content of
their habitat.
