CARBOHYDRATE UTILIZATION BY BEEF THYROID TISSUE

Carbohydrate utilization by beef thyroid tissue.

Preliminary to a study of various pathological thyroid states, it was considered necessary to investigate first the carbohydrate metabolism of the normal gland. Also, it was thought that the information gained regarding the function and energetics of the normal gland might eventually provide an insight into the mechanism of formation of the hormone, thyroxine. Although numerous studies related ...

Complex Carbohydrate Utilization by the Healthy Human Microbiome

The various ecological habitats in the human body provide microbes a wide array of nutrient sources and survival challenges. Advances in technology such as DNA sequencing have allowed a deeper perspective into the molecular function of the human microbiota than has been achievable in the past. Here we aimed to examine the enzymes that cleave complex carbohydrates (CAZymes) in the human microbio...

Carbohydrate utilization by the Lyme borreliosis spirochete, Borrelia burgdorferi.

Growth kinetic analyses of Borrelia burgdorferi indicated that this bacterium can utilize a limited number of carbon sources for energy: the monosaccharides glucose, mannose, and N-acetylglucosamine, the disaccharides maltose and chitobiose, and glycerol. All of these carbohydrates are likely to be available to B. burgdorferi during infection of either vertebrate and arthropod hosts, enabling d...

Thyroid-stimulating Hormone Binding to Beef Thyroid Membranes

The effect of sugars on ‘*“I-thyroid-stimulating hormone binding to beef thyroid membranes was studied to determine their role in thyroid-stimulating hormone (TSH) binding. At 0.1 M concentration, N-acetylneuraminic acid produced a 3to 7-fold increase in TSH binding, was the only sugar to enhance TSH binding, and did so whether binding was determined in the cyclase medium or under conditions of...
