Glucose intake

Koalas Phascolarctos cinereus) increase their glucose intake by 20% if they eat Eucalyptus spp. foliage, which requires conjugation reactions with glucuronic acid for excretion (Eberhard etal, 1975). Goats and sheep eat more of a toxic diet if given surplus food, which helps detoxication (Provenza, 2004). 

It can be converted to fat and stored inside cells. This is under normal conditions taking place in the adipocytes. The stores are practically unlimited. A year s glucose intake can be stored as 40 kg fat. 

Miscellaneous thoracic abnormalities (pectus excavatum), female sex, hyperventilation, glucose intake and ionic disorders etc. 

The disposition of a high glucose intake is presented in Figure 22-11.

Hyperkalemia may occur in renal disease and adrenal insufficiency owing to impairment of normal secretory mechanisms. Metabolic acidosis, in particular diabetic acidosis, and catabolism of cellular protein in starvation or fever cause K+ release from cells. Treatment consists of correction of the acidosis and promotion of cellular uptake of K+ by administration of insulin, which enhances glucose intake. In severe cases, ion exchange resins given orally bind K+ in intestinal secretions.

To measure the level of d-[6- H] glucose intake in Caco-2 cells, tritium-labeled glucose and immature LJE were added to a culture medium. Phloridzin is an inhibitor of sodium-dependent glucose transporters. Glucose intake was significantly suppressed in phloridzin-treated Caco-2 cells, but not in those treated with immature LJE (Fig. 15.7). 

Hormones involved in metabolism are responsible for the regulation of fuel storage in excess of current requirements as well as their mobilization upon increased demand [10]. Blood glucose levels are maintained within narrow limits despite wide fluctuations in glucose intake for proper functioning of the body, particularly of the nervous system. Insulin is the sole regulator of anabolic reactions... 

Figure 6 Glucose time dependence for an oral glucose tolerance test of a diabetic (trace A) and a healthy subject (trace B). Time is after glucose intake. The administration of insulin is usually not performed, but exemplifies the difficulties in control of blood glucose, since the hypoglycemic range is reached later. The central unshaded area shows schematically the normal and tolerated concentration ranges for subjects undergoing this test.

Rapid glucose intake with insulin response... 

Although this schedule is designed for infants, it is equally applicable to adults. The schedule is divided into two phases, an initial one during which the patient is adapting to the increasing glucose intake and a later one when he has achieved a more stable state metabolically. However, in the face of intermittent stress (i. ., surgery, infection, etc.), the schedule outlined under the initial period should be adopted since metabolic complications under these conditions are likely to be more frequent.
