Amino Acid Composition

The amino acid profile of soy peptides is analogous to that of soy protein, exhibiting a high abundance of essential amino acids, including lysine, tryptophan, and leucine. Notably, glutamic acid and aspartic acid are present in significant quantities, constituting crucial components of numerous peptide sequences within soy peptides. For instance, glutamic acid demonstrates a relatively high proportion and participates in diverse physiological functions, including serving as a precursor for neurotransmitters and regulating intracellular acid-base balance.

Peptide Bond Structure

Soy peptides are composed of multiple amino acids linked via peptide bonds. A peptide bond represents an amide linkage (-CO-NH-) formed between two amino acid residues. This bonding arrangement confers specific spatial conformations to soy peptides, and variations in peptide sequence and structure dictate their distinct biological activities. By way of illustration, certain specific peptide sequences can interact with receptors on the surface of human cells, thereby exerting immunomodulatory effects.
