Research Progress of Structure-Activity Relationship of Calcium Chelat-ing Peptides Derived from Different Food Proteins
Insufficient calcium intake can lead to symptoms such as osteoporosis,so peptide-calcium chelates have been widely concerned as a next-generation calcium supplement.Calcium chelates derived from food proteins have the unique advantages of wide availability and excellent perfor-mance.This review summarizes calcium chelates from different animal sources,aquatic resources,and plant sources,with a focus on analyzing the influence of peptide molecular weight,amino acid sequence and position,specific amino acid groups,and peptide spatial structure on the binding ca-pacity of peptides with calcium.By exploring the structure-activity relationship of peptide-calcium chelation,the purpose is to understand the inter-action mechanism between peptide and calcium,and develop a new calcium supplement product with better quality and high calcium binding force.
