Digestive system
: Salivary digestion
The Enzymes
1 - Amylase
2 - Lingual lipase
* The reactions "focus to color below"
starch+Amylase↦Soluble starch+Amylase↦Erythrodextrin+Amylase↦Acrodextrin(colorless) +Amylase↦Dextrin+Amylase↦Maltose+Amylase↦Glucose
The Experiments :
1) Acronic point
The steps :
1 - Add 1ML of saliva to tube. ,with 9ML NACL to make diluted saliva 1:10
2 - Add drop of iodin to 6 or 7 tubes "drop to each tube "
3 - Add 5 ML of starch + 1 ML of diluted saliva
4 - Add drop of the solution every 1 minute to one of iodin tubes "tube every minute "
conclusion
Rich enzymes saliva will change its color quickly like reactions above
1) Detection of No3
Saliva + H2SO4 + KI + starch ➟ Blue color
Because
