  • Essay On Salivary Amylase

    However a lot of work has been done to look at how saliva is produced, including some of its benefits such as preventing dental caries (Dawes 1970). Some studies have also looked at how the changes in salivary amylase can correlate to stress levels in an individual (Douglas et al. 2007). The main research that has been conducted to look at the relationship between salivary amylase and ancestral diet is a paper by Perry and his colleagues titled, “Diet and the evolution of human amylase gene copy…

  • Starch Experiment

    Analysis and Discussion The hypothesis that amylase would no longer hydrolyse the starch solution into maltose past 37°C was not supported by the data. Fig 1b, Fig 2.1 and Fig 2.2 all show the colour samples for various temperatures taken at increments of 10 seconds up to 40 seconds. Initially, 4°C was the slowest followed by 19°C then 37°C, 45°C, 80°C and 60°C being the fastest acting in the first 30 seconds. 80°C was the second-fastest acting temperature up until 20 seconds, but slowed down…
