Amino acids have their lowest solubility at their isoelectric point

the verdict
COMMON KNOWLEDGE
Legacy classification; evidence review pending
Recorded sources
no sources on either side

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that amino acids have their lowest solubility at their isoelectric point?

Proteins and amino acids have their minimum solubility at their isoelectric point due to having a net zero charge, which minimizes electrostatic repulsion and promotes aggregation.

The analysis

The claim that amino acids and proteins have their lowest solubility at their isoelectric point is a fundamental biochemical principle taught as common knowledge, supported by basic physical chemistry and corroborated by studies describing protein precipitation at the isoelectric point.
