We used a double-labeling technique to compare the metabolism of complex carbohydrates by skin fibroblasts from patients with rheumatic heart disease and from ageand sex-matched normal controls. Fibroblasts were subcultured through a similar number of passages prior to their growth in the presence of "Cor H-labeled glucosamine, a precursor of complex carbohydrates. At the preconfluent, confluen...

Structural carbohydrates are those that are resistant to the horse’s digestive enzymes. These carbohydrates occur in the cell wall portion of the plant and they must be fermented by bacteria living in the horse’s gut before they can be utilized by the horse. As a group, these carbohydrates are called plant fiber and they consist primarily of cellulose and hemicellulose. The various types of non...

The consumption of nondigestible carbohydrates is perceived as beneficial by health professionals and the general public, but the translation of this information into dietary practice, public health recommendations, and regulatory policy has proved difficult. Nondigestible carbohydrates are a heterogeneous entity, and their definition is problematic. Without a means to characterize the dietary ...

The C. elegans genome contains sequences similar to a large number of mammalian genes implicated in the assembly, processing, and modification of glycans. In recent years, spectacular progress has been made in developing and refining tools to obtain structural information with small amounts of material, increasing our understanding of glycan structural complexity in this organism. These approac...

Cycad biology, ecology, and horticulture decisions are not supported by adequate research, and experiments in cycad physiology in particular have been deficient. Our recent report on free sugar content in a range of cycad taxa and tissues sets the stage for developing continued carbohydrate research. Growth and development of cycad pollen, mediation of the herbivory traits of specialist pollina...
