[Lymphocyte succinate dehydrogenase and acid phosphatase activity in infants on artificial feeding with a varying
Insights
This study investigated how protein intake affects enzyme activity in infants. Higher succinate dehydrogenase activity in lymphocytes correlated with increased dietary protein, suggesting it can help determine optimal infant formula protein levels.
Area of Science:
- Biochemistry
- Pediatric Nutrition
- Enzymology
Background:
- Infant formula composition is critical for healthy development.
- Understanding nutrient metabolism in early life is essential.
- Enzyme activity can serve as a biomarker for nutritional status.
Purpose of the Study:
- To investigate the relationship between dietary protein content and enzyme activity in infants.
- To evaluate succinate dehydrogenase and acid phosphatase activity in lymphocytes of formula-fed infants.
- To determine if enzyme activity can indicate optimal protein levels in infant formulas.
Main Methods:
- Studied blood lymphocytes from healthy infants (0-6 months) on formula diets.
- Varied dietary protein content (2-2.5, 3-3.5, 4-4.5 g/kg).
- Measured succinate dehydrogenase and acid phosphatase enzyme activity.
Main Results:
- Succinate dehydrogenase activity showed a clear correlation with dietary protein levels.
- Acid phosphatase activity was also measured but its relation to protein was not the focus.
- Infants fed formulas with higher protein content exhibited greater succinate dehydrogenase activity.
Conclusions:
- Succinate dehydrogenase activity in lymphocytes is a potential indicator of protein adequacy in infant formulas.
- This enzyme activity may serve as an additional method to optimize protein content for formula-fed infants.
- Further research can validate this biomarker for personalized infant nutrition.
Abstract:
The activity of succinate dehydrogenase and acid phosphatase in blood lymphocytes was studied in healthy children of the first half year of life kept on formula feeding with the adapted milk mixtures "Malyutka" and "Malysh". The content of protein in the children's diet varied over the range of 2-2.5; 3-3.5 and 4-4.5 g/kg. The activity of succinate dehydrogenase has been shown to be related to the protein content in the diet. The results obtained point to the possibility of assessing this activity as an additional method for determination of the optimum protein content in formula feeding.
