Trehalose — living evidence map

The Atlas page holds the claims; this is how its evidence evolved.

Summary

Trehalose is a disaccharide stabilizer; compared with sucrose it is more strongly excluded from proteins in solution, but more prone to phase separation and crystallization in frozen solutions, and it is hygroscopic. · pmid:37918545

Mechanism

Its stabilization of ribonuclease A could be fully accounted for by the change in transfer free energy on unfolding. · pmid:9127936

Identity

PubChem CID 181978: Trehalose, dihydrate, C12H26O13, 378.33 g/mol. · pubchem:181978

CAS registry number 6138-23-4. · pubchem:181978

IUPAC name: (2R,3S,4S,5R,6R)-2-(hydroxymethyl)-6-[(2R,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxyoxane-3,4,5-triol;dihydrate. · pubchem:181978

Structure

No structure representation on record. PepJunkie draws only what an authoritative record supplies; for a peptide that is the residue sequence, and none has been curated for Trehalose yet.

Dose evidence, rung by rung

A studied human dose exists on file. Open the rung: the dose is the paper's, in its context, never PepJunkie's.
