Trehalose is a natural non-reducing disaccharide composed of two α-glucose units. It is found in all major groups of organisms except vertebrates, has biological functions as an osmolyte, storage reserve, and stress protectant, and has diverse commercial applications. Trehalose can also induce or enhance autophagy.

Decreasing glycerol content by co-supplementation of Trehalose and taxifolin hydrate in ram semen extender: Microscopic, oxidative stress, and gene expression analyses
Cryobiology 2020 Oct;96:19-29.PMID:32890464DOI:10.1016/j.cryobiol.2020.09.001.
This study aimed to evaluate the comparative effects of taxifolin hydrate and Trehalose on the quality of frozen-thawed ram spermatozoa for the first time. Ejaculates collected from six mature rams were pooled, and divided to eight equal aliquots to extend them with different concentrations of glycerol (%5 and %3), taxifolin hydrate (10, 100, and 500 μM), and Trehalose (60 mM) as eight groups (G5T0, G5T10, G5T100, G5T500, G3T0, G3T10, G3T100, and G3T500). After freeze-thawing process of cryopreservation, microscopic and oxidative stress parameters, and gene expression levels were investigated for understanding of possible impacts of taxifolin hydrate and Trehalose. The study showed that G3T10 resulted in the highest post-thawed viability and mitochondrial activity. Moreover, all extenders with taxifolin hydrate reduced DNA fragmentation in comparison to G5T0, but DNA damage was prevented at the highest rate in presence of G5T10. The level of LPO significantly decreased in the groups G5T500 and G3T100, and the expression levels of NQO1, GCLC, and GSTP1 genes significantly increased in the groups G5T100, G5T500, G3T10, and G3T100 compared to the group G5T0. Finally, co-supplementation of tris-based extender having 3% glycerol with 60 mM Trehalose and 10 μM taxifolin hydrate in cryopreservation extender may be recommended to improve the quality of post-thawed ram spermatozoa. However, further in vivo and in vitro studies are suggested to evaluate fertility rates of frozen-thawed ram spermatozoa co-supplemented with Trehalose and taxifolin hydrate.
Trehalose and tardigrade CAHS proteins work synergistically to promote desiccation tolerance
Commun Biol 2022 Oct 1;5(1):1046.PMID:36182981DOI:10.1038/s42003-022-04015-2.
Tardigrades are microscopic animals renowned for their ability to survive extreme desiccation. Unlike many desiccation-tolerant organisms that accumulate high levels of the disaccharide Trehalose to protect themselves during drying, tardigrades accumulate little or undetectable levels. Using comparative metabolomics, we find that despite being enriched at low levels, Trehalose is a key biomarker distinguishing hydration states of tardigrades. In vitro, naturally occurring stoichiometries of Trehalose and CAHS proteins, intrinsically disordered proteins with known protective capabilities, were found to produce synergistic protective effects during desiccation. In vivo, this synergistic interaction is required for robust CAHS-mediated protection. This demonstrates that Trehalose acts not only as a protectant, but also as a synergistic cosolute. Beyond desiccation tolerance, our study provides insights into how the solution environment tunes intrinsically disordered proteins' functions, many of which are vital in biological contexts such as development and disease that are concomitant with large changes in intracellular chemistry.
Preservation of carbon dioxide clathrate hydrate in the presence of Trehalose under freezer conditions
Sci Rep 2016 Jan 19;6:19354.PMID:26780867DOI:10.1038/srep19354.
To investigate the preservation of CO2 clathrate hydrate in the presence of sugar for the novel frozen dessert, mass fractions of CO2 clathrate hydrate in CO2 clathrate hydrate samples coexisting with Trehalose were intermittently measured. The samples were prepared from Trehalose aqueous solution with Trehalose mass fractions of 0.05 and 0.10 at 3.0 MPa and 276.2 K. The samples having particle sizes of 1.0 mm and 5.6-8.0 mm were stored at 243.2 K and 253.2 K for three weeks under atmospheric pressure. The mass fractions of CO2 clathrate hydrate in the samples were 0.87-0.97 before the preservation, and CO2 clathrate hydrate still remained 0.56-0.76 in the mass fractions for 5.6-8.0 mm samples and 0.37-0.55 for 1.0 mm samples after the preservation. The preservation in the Trehalose system was better than in the sucrose system and comparable to that in the pure CO2 clathrate hydrate system. This comparison indicates that Trehalose is a more suitable sugar for the novel frozen carbonated dessert using CO2 clathrate hydrate than sucrose in terms of CO2 concentration in the dessert. It is inferred that existence of aqueous solution in the samples is a significant factor of the preservation of CO2 clathrate hydrate in the presence of sugar.
The Role of Trehalose for the Stabilization of Proteins
J Phys Chem B 2016 May 26;120(20):4723-31.PMID:27135987DOI:10.1021/acs.jpcb.6b02517.
Understanding of how the stabilization mechanism of Trehalose operates on biological molecules against different types of environmental stress could prove to gain great advancements in many different types of conservation techniques, such as cryopreservation or freeze-drying. Many theories exist that aim to explain why Trehalose possesses an extraordinary ability to stabilize biomolecules. However, all of them just explain parts of its mechanism and a comprehensive picture is still lacking. In this study, we have used differential scanning calorimetry (DSC) and viscometry measurements to determine how the glass transition temperature Tg, the protein denaturation temperature Tden, and the dynamic viscosity depend on both the Trehalose and the protein concentration in myoglobin-trehalose-water systems. The aim has been to determine whether these physical properties are related and to gain indirect structural insights from the limits of water crystallization at different concentration ratios. The results show that for systems without partial crystallization of water the addition of protein increases Tg, most likely due to the fact that the protein adsorbs water and thereby reduces the water content in the trehalose-water matrix. Furthermore, these systems are generally decreasing in Tden with an increasing protein concentration, and thereby also an increasing viscosity, showing that the dynamics of the trehalose-water matrix and the stability of the native structure of the protein are not necessarily coupled. We also infer, by analyzing the maximum amount of water for which ice formation is avoided, that the preferential hydration model is consistent with our experimental data.
Thermodynamic, hydration and structural characteristics of alpha,alpha-trehalose
Front Biosci (Landmark Ed) 2009 Jan 1;14(9):3523-35.PMID:19273290DOI:10.2741/3468.
A nonreducing disaccharide, alpha,alpha-trehalose, accumulates endogenously in diverse anhydrobiotic organisms in their dehydrating process or prior to their desiccation, being thought to have a protective function either as a water replacement molecule or as a vitrification agent in the dry state. Trehalose acts also as a protectant against physiological stress, including freezing, ethanol and oxidation. To elucidate the origin of these different functions of this sugar, it is necessary to obtain a deep insight into the physicochemical properties of Trehalose at the molecular level. In this review, we focus our attention on the thermodynamic, hydration and structural properties of carbohydrates, and extract the characteristic feature of Trehalose. On the basis of these findings, we subsequently discuss the underlying mechanism for protein stabilization by Trehalose in solution and for its anitoxidant function on unsaturated fatty acids.
