Reserve Galactomannans and Glucomannans in Seeds, Bulbs, and Rhizomes

Abstract

Temperature dependence of nuclear decays in metallic environments is a controversial issue. We measured the temperature dependence of the β + -decay half-life of 22 Na implanted into the metal host of palladium. It is found that the β + -decay half-life of 22 Na in the metal Pd cooled to T = 15 K is shorter by 0.46(14)% than that at room temperature. The result is consistent in sign with, but clearly smaller than, the estimated one by the Debye model.

Rheological Properties of High‐Methoxyl Pectin and Locust Bean Gum Solutions in Steady Shear

“…PECTINS are polysaccharides composed mainly of (1 + 4) linked a-D-galactopyranosyluronic acid units, with some of the carboxyl groups in the methyl ester form (Aspinall, 1970;BeMiller, 1986). Locust bean gum (LBG) is a mucilage from the seed endosperm of the carob tree (Ceratonia siliqua, L.) containing galactomannan polysaccharides based on a (1 + 4) linked P-D-mannopyranosyl backbone partially substituted with single (1 + 6) linked a-D-galactopyranosyl side groups (Smith, 1948;Stepanenko, 1960).…”
