Solution Overview
Problem
The effectiveness of existing unsaturated fatty acids for cryopreservation and disease treatment is limited and associated with side effects, necessitating a new fatty acid that enhances membrane fluidity and is suitable for biological applications.
Innovation Solution
A fatty acid with two double bonds interrupted by methylene groups, forming a ring-like structure, particularly in the cis/cis configuration, which increases membrane fluidity and biocompatibility, and can be produced through lipid extraction from psychrotolerant bacteria like Chryseobacterium frigidisoli, suitable for cryopreservation and therapeutic uses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing unsaturated fatty acids are used for cryopreservation and disease treatment, then membrane fluidity is increased to some extent, but effectiveness is limited and side effects occur
Solution Approach 1:
The patent changes the structural parameters of fatty acids by introducing a specific configuration with two double bonds interrupted by two methylene groups (methylene-interrupted double bonds) in a cis/cis configuration. This structural parameter change creates a new fatty acid with enhanced membrane fluidity and biological activity, achieving better effectiveness while reducing side effects compared to conventional unsaturated fatty acids
Solution Approach 2:
The invention creates a composite structural feature within the fatty acid molecule by combining saturated and unsaturated segments with a specific arrangement of methylene-interrupted double bonds. This composite structure integrates the stability of saturated regions with the fluidity-enhancing properties of unsaturated regions, producing a fatty acid with superior performance for cryopreservation and therapeutic applications
2Stability of the object's composition
If saturated fatty acids and longer carbon chains are used in cell membranes, then membrane structure becomes more rigid and ordered, but membrane fluidity decreases
Solution Approach 1:
The patent applies local quality by creating specific regions within the fatty acid molecule with different properties: saturated segments provide structural stability and rigidity, while the cis/cis methylene-interrupted double bond regions provide localized fluidity enhancement. This spatial differentiation of properties within the single fatty acid molecule allows simultaneous achievement of membrane structure stability and adequate fluidity
Solution Approach 2:
The invention changes the structural parameters by introducing cis-configured double bonds with methylene interruptions at specific positions along the carbon chain. These parameter changes create structural 'kinks' that prevent tight packing of fatty acid chains, thereby maintaining membrane fluidity while preserving overall structural integrity through the saturated portions
3Ease of operation
If unsaturated fatty acids with cis double bonds are used, then membrane fluidity is increased, but structural stability is reduced
Solution Approach 1:
The patent implements local quality by confining the fluidity-enhancing cis double bonds with methylene interruptions to specific local regions within the fatty acid chain, while the remainder of the molecule maintains saturated, stable structures. This localized approach allows fluidity enhancement without compromising overall molecular stability
Solution Approach 2:
The invention creates a composite molecular structure combining saturated stable segments with unsaturated fluidity-promoting segments featuring cis/cis methylene-interrupted double bonds. This composite architecture integrates conflicting properties at the molecular level, achieving both structural stability and enhanced membrane fluidity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The new fatty acid significantly increases membrane fluidity, improves cell survival and growth rates during cryopreservation, and is effective in treating cardiovascular diseases, diabetes, and other metabolic disorders by enhancing membrane permeability and nutrient absorption, while reducing cholesterol and blood sugar levels.
Implementation Method 1
the two double bonds interrupted by two methylene groups can form a ring-like structure, which leads to the fatty acid increasing membrane fluidity when integrated into a membrane. It is particularly preferred that the two double bonds interrupted by two methylene groups are in the cis configuration.
Implementation Method 2
which can be produced through lipid extraction from psychrotolerant bacteria like Chryseobacterium frigidisoli
