Analysing the Biochemistry of Saliva: Flow, Total Protein, Amylase Enzymatic Activity and Their Interconnections

This study examines the biochemical profile of saliva, focusing on flow rate, total protein concentration, and the enzymatic activities of amylase and catalase. Thirty-one participants underwent saliva sampling before and after physical activity to assess how these biochemical markers respond to physiological stress. The findings reveal a significant positive correlation between protein concentration and amylase activity, especially in post-exercise conditions, suggesting saliva’s potential as a non-invasive biomarker for systemic health and stress responses. These results highlight saliva’s utility in health diagnostics, enabling more accessible monitoring of health status and physiological stress.
