Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current creatine supplementation methods, such as creatine monohydrate, face issues with stability, solubility, and conversion to creatinine, particularly in aqueous solutions, which limits their effectiveness and convenience for increasing muscle creatine levels.
Innovation Solution
The development of creatine-fatty acid compounds bound via an amide linkage, specifically using saturated and unsaturated fatty acids, enhances stability, solubility, and bioavailability by forming compounds like 2-(3-butyryl-1-methylguanidino)acetic acid and (Z)-2-(3-hexadec-9-enoyl-1-methylguanidino)acetic acid through a synthesis process involving acyl halides and creatine in dichloromethane with a catalytic pyridine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If creatine monohydrate is used for supplementation, then muscle creatine levels can be increased, but the compound suffers from poor stability, low solubility, and conversion to creatinine in aqueous solutions
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure of creatine through esterification with fatty acids. This transforms creatine from a zwitterionic compound with poor solubility to an esterified derivative with improved solubility and stability characteristics. The esterification reaction changes the chemical parameters of creatine, creating compounds that resist conversion to creatinine while maintaining or enhancing solubility in aqueous and non-aqueous solutions.
Solution Approach 2:
The patent creates composite chemical structures by combining creatine with various fatty acids through amide linkages. These creatine-fatty acid compounds represent composite materials that integrate the energy-metabolism benefits of creatine with the structural and stability properties of fatty acid chains. The composite structure resolves the contradiction by providing both improved solubility and enhanced stability against creatinine conversion.
2Productivity
If creatine is supplemented in aqueous solutions, then absorption can occur, but the compound converts to creatinine which reduces effectiveness
Solution Approach 1:
The esterification of creatine with fatty acids fundamentally changes the chemical parameters of the molecule, particularly its resistance to hydrolysis and spontaneous decomposition. The esterified creatine compounds are more resistant to conversion to creatinine in aqueous solutions, thereby maintaining their effectiveness during storage and absorption. This parameter change enables the compound to remain stable in the aqueous environment of the gastrointestinal tract while being absorbed.
3Use of energy by moving object
If standard creatine supplementation is used, then muscle energy metabolism is supported, but additional functional benefits are not provided
Solution Approach 1:
The patent applies universality by designing creatine-fatty acid compounds that perform multiple functions simultaneously. These compounds not only support muscle energy metabolism through creatine's phosphocreatine system but also provide the benefits of fatty acid supplementation. The multi-functional compound delivers both creatine's ergogenic effects and fatty acids' metabolic benefits, enhancing adaptability and versatility compared to standard creatine supplementation alone.
