Pea-Derived Peptides for Sarcopenia Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for sarcopenia lack effective muscle-building drugs, with existing options often being hormones with unclear benefits, and there is a need for peptide-based solutions derived from food sources that can promote muscle protein synthesis and absorption.
Innovation Solution
A pea-derived peptide with specific amino acid sequences (PP1, PP2, PP3, PP4, and PP5) is developed through enzymatic hydrolysis and purification methods, which can promote muscle-building effects by activating growth and proliferation signaling pathways, increasing testosterone levels, and enhancing ATPase activity in skeletal muscle mitochondria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If hormone-based drugs are used to treat sarcopenia, then muscle mass may be increased, but the benefits are not fully clarified and safety is uncertain
Solution Approach 1:
The patent replaces uncertain long-term hormone therapy with short-chain peptide molecules (5-20 amino acids) that provide targeted muscle-building effects without the long-term safety concerns of hormones. These peptides are derived from pea protein and have specific sequences (PP1-PP5) that activate muscle growth pathways transiently and safely.
Solution Approach 2:
The patent changes the molecular parameters from large hormone molecules to small peptide fragments with specific amino acid sequences. This parameter change enables selective activation of muscle protein synthesis pathways while avoiding the systemic side effects of hormones, achieving muscle mass increase with improved safety profile.
2Quantity of substance
If protein supplementation is increased to prevent sarcopenia, then muscle protein synthesis is promoted, but absorption and utilization are reduced in elderly due to digestive system degradation
Solution Approach 1:
The patent segments large protein molecules into small peptide fragments (5-20 amino acids) through enzymatic hydrolysis. This segmentation increases the surface area for absorption and reduces the metabolic burden on the digestive system, making protein supplementation effective for elderly individuals with compromised digestive function.
Solution Approach 2:
The patent uses peptide molecules as intermediaries between dietary protein and muscle tissue. These peptides serve as pre-digested building blocks that can be directly absorbed and utilized for muscle protein synthesis, bypassing the need for complete protein digestion and improving overall utilization efficiency.
3Quantity of substance
If whole protein is consumed to improve muscle building, then amino acid content is high, but absorption rate is lower compared to peptide forms
Solution Approach 1:
The patent segments proteins into peptides with optimized length (5-20 amino acids) that balance amino acid content with absorption kinetics. This segmentation creates molecules small enough for rapid absorption while maintaining sufficient amino acid density to drive muscle protein synthesis.
Solution Approach 2:
The patent optimizes the molecular weight and amino acid sequence parameters of the peptides to enhance absorption rate. The specific peptide sequences (PP1-PP5) are designed to facilitate rapid uptake by muscle cells while providing adequate amino acid composition for muscle building.

AI summary
A pea-derived peptide with a muscle-building effect and a preparation method thereof, and a drug and use, are disclosed. A pea protein is subjected to enzymatic hydrolysis, and five polypeptides with muscle-building effect are obtained by separation as separate peptide fragments. In an in vitro aging skeletal muscle cell assay, changes are analyzed in a gene expression level of regulatory pathways related to skeletal muscle cell proliferation and differentiation, apoptosis and autophagy, and protein synthesis and degradation. In addition, animal experiments are conducted to study the muscle-building effect and a corresponding mechanism of the pea-derived peptide. This shows that the five polypeptide sequences have a significant muscle-building effect, usable as a polypeptide drug for the treatment of sarcopenia.
