G Cori (1886-1957) – nee Gerty Theresa Radniz was born into a Jewish family in Prague. She entered medical school at the University of Prague in 1914 where she met Carl Cori as a classmate with common interests. They obtained medical degree in 1920. Gerty then converted t o C a t h o l i c i s m a n d m a r r i e d Carl. Thereafter they moved to Vienna, where Gerty worked at a Children’s Hospit...

1. Schistosoma mansoni utilizes in 1 hour an amount of glucose equivalent to one-sixth to one-fifth of its dry weight. Over 80 per cent of the metabolized glucose is converted to lactic acid by this organism. 2. The rates of glucose utilization and of lactic acid production by S. mansoni are the same under aerobic and under anaerobic conditions. 3. A high rate of lactic acid production and the ...

After a single injection of uniformly labeled glucose-Cl4 into rats (1) and dogs (2), the specific activity of plasma glucose, highest immediately after the injection, declines exponentially. The decline is due to a progressive replacement of the tagged compound with relatively non-labeled glucose. The slope or rate constant of the decay curve denotes the rate of turnover of the glucose pool ex...

Oxidative energy production is by far dominant in living animal muscles, with the exception the short periods of severe stress, where the aerobic capacity is exceeded, and formation of large amounts of lactate and protons will take place. Energy consumption in muscle cells continues post-mortem with formation of large amounts of lactate and protons, because the aerobic processes for energy prod...

Serum insulin, blood sugar, and growth hormone levels were measured in response to a 50g oral glucose tolerance test in 10 patients with proven dystrophia myotonica. Three patients belonged to one family; seven patients had no known family history of the disease. One patient, a chronic invalid aged 56 years, produced a mild diabetic glucose tolerance curve and a delayed prolonged rise in serum ...

Calystegines are hydroxylated nortropane alkaloids derived from the tropane alkaloid biosynthetic pathway. They are strong glycosidase inhibitors and occur in vegetables such as potatoes, tomatoes, and cabbage. Calystegine accumulation in root cultures was described to increase with carbohydrate availability. Whether this is indicative for the in planta situation is as yet unknown. Potatoes are...

A brief review of the presence and the age-associated changes of enzymatic activities of the lens metabolism is given. A consideration of the data on the activities of some enzymes of different animal species indicates that changes in lens metabolism related to age should be controlled by multiple sampling at intervals of aging over a wide age span rather than at fust two ages. Changes in the c...

Cellulose is the most abundant biopolymer in the world, the main load-bearing element in plant cell walls, and represents a major sink for carbon fixed during photosynthesis. Previous work has shown that photosynthetic activity is partially regulated by carbohydrate sinks. However, the coordination of cellulose biosynthesis with carbohydrate metabolism and photosynthesis is not well understood....

The domestic cat's wild ancestors are obligate carnivores that consume prey containing only minimal amounts of carbohydrates. Evolutionary events adapted the cat's metabolism and physiology to this diet strictly composed of animal tissues and led to unique digestive and metabolic peculiarities of carbohydrate metabolism. The domestic cat still closely resembles its wild ancestor. Although the c...

Studies initially concerned with the role of nutrient carbohydrates in the formation of capsular hyaluronic acid by various strains of Streptococcus pyogenes led to the finding that the end products of glucose and galactose dissimilation in these organisms differ quantitatively (Steele et al., 1954). This paper is a report of further investigations on the latter aspect of the carbohydrate metab...
