Reference of rel-(3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraolOn June 1, 2022, Tang, Luying; Sun, Yanhui; Ge, Peipei; Chen, Lei; Cheung, Peter C. K.; Ding, Zhongyang; Fang, Jinshan published an article in International Journal of Biological Macromolecules. The article was 《Biogenetic nanocarriers with enhanced pH stability formed by zein and selectively depolymerized mushroom hyperbranched β-glucans》. The article mentions the following:
Hyperbranched polysaccharide from Pleurotus tuber-regium (PTR-HBPS) is a βamp;beta;-glucan with high degree of branching (DB, 0.69) and a mol. weight (Mw) of 31.2 x 105 g/mol with mixed βamp;beta;-1, 4/ββ-1, 4, 6β/β-1, 6 glucosidic linkages. PTR-HBPS was depolymerized by cellulase and βamp;beta;-glucosidase under optimized conditions to form PC (PTR-HBPS depolymerized by cellulase) and PG (PTR-HBPS depolymerized by βamp;beta;-glucosidase) fractions with a min. Mw of 2.74 x 105 and 3.98 x 105 g/mol, resp. PC fractions had no significant changes for its primary structure in terms of glycosidic linkages, DB, and triple helical structure, while the DB of PG fractions was reduced to 0.63 with the loss of triple helical structure. Nanoparticles fabricated by PC fractions with zein showed better stability under different pH conditions. Enzymic depolymerized low Mw β-glucan derived from PTR-HBPS with similar structural characteristics as the native one has potential as nanocarriers for food bioactive substances.
