Estimation of bioactive peptide content of milk from different species using an in silico method

Abstract

This study assessed the bioactive peptides content of milk from different species, including humans, camel, bovine, buffalo, donkey, sheep, goat, and horse. The highest and lowest concentrations of total digestion-resistant peptides were estimated in sheep and human milk. Donkey milk casein contains a higher angiotensin-converting enzyme (ACE) inhibitory, dipeptidyl peptidase III (DPP-III) inhibitory, DPP-IV inhibitory, and antioxidant peptides. On the other hand, camel whey protein contains the highest ACE-inhibitory peptides. To discover BPs with immunomodulatory and cholesterol-lowering functions, goat milk casein and sheep milk whey protein can be considered, respectively.
