Arginine - <proteinogenic> -

--- in construction

longest chain, required for long flex, skeletal muscles

required for growth of size of body

highest amine count of all amino acids

matches up with lysine, then disabled body function

digestive enzyems of pancreas un-bind lysine to arginine to free it

trypsin and trypsin-like protein enzymes to digest proteins into amino acids

based on histidine and serine, originally called serine-enzymes but today would be histidine/serine-enzymes
