lipase and milk fat
Fats, such as the fats in milk, need to be digested by your body. They are broken down into fatty acids and glycerol by an enzyme called lipase. You can do this in the...
fermentation
In the manufacture of yoghurt, bacteria turn lactose into lactic acid. The acid denatures or spoils the milk protein and sets it solid. In the process, the milk starts to taste sour and its...
changes in an aquarium
Life in any aquatic habitat has to be supported by oxygen. We are all too familiar with rivers and streams where the oxygen supply has been exhausted and the river dies. The production and...
pH data on souring milk
The label on my milk bottle tells me how long the milk will ‘last’ at different temperatures. What do they measure to make this assessment? Is it the pH? I summoned patience, collected a glass...
measure lipase enzyme activity
If you’ve a couple of pH electrodes and sensors, the following is one of the most successful enzyme measurements I’ve tried. Before bothering further, connect the pH electrodes to a data logger and ensure...
how to store a pH probe
I read somewhere that pH probes do not last forever and that may be so. It was certainly true for the draw full of pH probes, all left to dry, that I found and...
acid-base titration
As acid drains into alkali the pH changes. This can be monitored using a pH sensor to produce an instant graph of pH against volume. The easy way of doing this is to not...
oxygen and pH sensors
oxygen sensor – my rating was *** / ++ Sensor is used in conjunction with an oxygen electrode. Good for demonstrations where you monitor photosynthesis, fermentation or where you re-breathe the air in plastic...
