Saliva contains which enzyme

Macromolecular nutrients such as protein and starch, but probably also fat, would have a neutral taste. We would only be able to taste pre-digested food that already contains individual amino acids and sugars. The calcium and phosphate ions leached from hydroxyapatite through the action of water and unbuffered acids would not be replaced.

The dental enamel would be demineralised and become porous. Bacteria could spread undisturbed and would cause caries through increased production of acids.

Food and saliva Preventing us from choking on food An important role of saliva during eating is based in its sliminess. Taste Saliva is essential for taste sensation. Saliva as a builder The hard matter of our teeth - enamel and dentine - consists of a very hard crystal called hydroxyapatite.

Source of building blocks Because of its specific properties water can dissolve out ions from salt crystals. Saliva in the biotope of the oral cavity Our cohabitants The many moist and warm surfaces in our mouth serve as an ideal habitat biotope for microorganisms, mainly bacteria, but also yeasts e.

Surviving in the biotope of the oral cavity Bacteria only stand a chance to survive in our mouth if they manage to hold on and not get swallowed. References Pedersen AM, et al.

Updated February 26, Major Enzymes in Saliva Salivary amylase also known as ptyalin breaks down starches into smaller, simpler sugars. Salivary kallikrein helps produce a vasodilator to dilate blood vessels. Lingual lipase helps to break down triglycerides into fatty acids and glycerides.
