We examined the seasonal variation in total non-structural carbohydrate (TNC) concentrations in branch, trunk, and root tissues of Anacardium excelsum, Luehea seemannii, Cecropia longipes, and Urera caracasana growing in a seasonally dry forest in Panama. Our main goals were: (1) to determine the
The accumulation of non-structural leaf carbohydrates is one of the most consistent plant responses to elevated CO2. It has been found in both fast-and slow-growing plants and is largely independent of the duration of exposure. Changes in leaf quality are thus to be expected, irrespective of other
In Central and South American traditional medicine, people use Cecropia obtusifolia Bertol (Cecropiaceae) for the treatment of diabetes mellitus. However, its hypoglycemic action mechanism at pancreatic and liver level has been poorly explored. The present research aimed to establish the
Cecropia obtusifolia and Marrubium vulgare have been widely used in Mexican traditional medicine for the control of type 2 diabetes. In order to evaluate the clinical effect produced by the aqueous extract from these species on type 2 non-controlled diabetes mellitus, a total of 43 outpatients were
Type 2 diabetes is an endocrine disease, which accounts for 9% of deaths worldwide. The aim of oral therapy is to reach normoglycemia to prevent later complications. Among glucose-lowering medications, alpha-glucosidase inhibitors delay the absorption of ingested carbohydrates, reducing the
The branched glucans glycogen and starch are the most widespread storage carbohydrates in living organisms. The production of semicrystalline starch granules in plants is more complex than that of small, soluble glycogen particles in microbes and animals. However, the factors determining whether
Sorbitol biosynthesis and regulation in freeze tolerant pupae of Hyalophora cecropia have been investigated as a function of temperature by 19F and 13C nuclear magnetic resonance (NMR) spectroscopy using several 13C-labeled and/or fluorine-substituted carbohydrates. 3-Deoxy-3-fluoro-D-glucose (3DFG)
A riboflavin-binding hexamerin isolated from pupal hemolymph of Hyalophora cecropia has a native M(r) of 510,000, subunit M(r) of 85,000, and a 5% carbohydrate content. An intrachain cross-link was confirmed in protease limit digests. Ellman titration confirmed the presence of a sulfhydryl group,
When Hyalophora cecropia hemolymph was injected into wandering Actias luna larvae, a methionine-rich hexamerin was selectively transferred to the host's fat body, and completely cleared from the hemolymph by the time of pupal eclosion. Donor arylphorin was 30-40% removed from the hemolymph, and
