Scientists have found that the sensitivity to salt is hidden in the concentration of certain proteins in the saliva of man, reports The Hindustan Times.
Specialists conducted a test with a group of volunteers, inviting them to assess the level of salt in the sodium chloride solution. Then volunteers were divided into two groups, depending on the obtained preliminary results. Methods using liquid chromatography and mass spectrometry experts have identified in the saliva of participants from different groups several proteins whose concentrations are different.
Differed also, the composition of salt. The volunteers, sensitive to salt in saliva was more endopeptidas - enzymes that cleave peptide bonds. According to experts, these enzymes can provoke enhanced the taste of salt.
