The Claim
Coffee polyphenols, specifically chlorogenic and caffeic acids, demonstrate increased solubility in proline-rich environments relative to water, indicating a thermodynamically favorable interaction between these polyphenols and proline residues.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Coffee compounds called polyphenols dissolve better in environments full of a substance called proline than in plain water, which suggests they like to stick together with proline.
See the scientific wording
Coffee polyphenols (chlorogenic and caffeic acids) exhibit increased solubility in proline-rich environments compared to water, suggesting a thermodynamically favorable interaction between these compounds and proline residues.
What the research says
1 studyStudy: Molecular mechanism of the interactions between coffee polyphenols and milk proteins
The study found that coffee compounds dissolve much better in environments full of proline (an amino acid) than in plain water, and they stick to proline because of friendly molecular interactions—exactly what the claim says.
