Function begins to return as soon as nutritional support is introduced, even before any tissue gain, suggesting an immediate and direct effect on cellular function. Skeletal and respiratory muscle function deteriorates steeply after a loss of 20% of body protein stores (equivalent to 15% total body weight loss) and improves by 10-20% within the first few days of nutritional support. 

Cyanocoba/am/n- Cyanocobalamin is rapidly absorbed from IM and subcutaneous injection sites the plasma level peaks within 1 hour. Once absorbed, it is bound to plasma proteins, stored mainly in the liver and is slowly released when needed to carry out normal cellular metabolic functions. Within 48 hours after injection of 100 to 1,000 meg of vitamin B-12, 50% to 98%... 

Weigh out dry protein and prepare a stock solution at a concentration of 3 mg/ml in the same solvent as used for the sample protein. Store up to 3 months at -20°C.

The human diet provides energy primarily from a mixture of carbohydrates and fats, with protein accounting for perhaps 12%-30% of total energy intake. As noted above, the potential for storing carbohydrates is limited. Furthermore, there are no protein stores in the body... 

Both are important in the transport and storage of oxygen in vertebrates. Hemoglobin, Hb, an heterotetramer that binds 02 cooperatively, is found in red blood cells. Myoglobin, Mb, an a-helical mononuclear globular protein, stores oxygen in the muscle tissue until it is required for oxidative phosphorylation. 

Chemical processes are caused by chemical reactions between the radiolytically produced ions and radicals and the molecules of the labeled proteins. They are very significant and rapidly diminish the u ful life of many labeled compounds. The degree of decomposition caused by secondary radiation is affected by the storage conditions of the protein. For instance, proteins stored in aqueous solutions are... 

Carbohydrates provide an energy boost, but only for the short term, such as during strenuous exercise. Our long-term energy needs are met by triacylglycerols, because they store 9 kcal/g, whereas carbohydrates and proteins store only 4 kcal/g. 

QS, like those of other plants, store proteins in the embryo to provide nutrients for growth and development (Herman and Larkins, 1999). In the food area, proteins stored in seeds are the source of the proteins consumed directly as food by humans (Shewry et al., 1995). Stored proteins provide building blocks for rapid growth upon seed and pollen germination (Herman and Larkins, 1999). Osborne (1924) introduced a classification of plant proteins based on their solubility in a series of solvents, such as albumins in water, and globulins in saline.

In practice, the data from real systems are less clean cut but show the same kinds of trend. Figure 5 shows the results obtained from samples of soya 7S proteins stored under different conditions and compared with fresh material... 

ABA was originally discovered because of its role in the dormancy of apical buds [20]. The correlation between the amount of ABA in apical buds and the depth of winter dormancy suggests that ABA plays a major role in the dormancy of this region. More controversial is the question as to whether ABA is involved in lateral bud dormancy as well [85]. Another major role of ABA is to induce the dormancy in maturing seeds of many species. At the same time, ABA induces the synthesis of proteins stored in seeds as... 

Another major cardiac injury biomarker is myoglobin, the cytoplasmic protein storing and shuttling oxygen from the cell surface to the mitochondria. This small protein can be easily measured by species-specific immunoassays (Spangenfhal and Ellis... 

In databases built using bottom-up approaches, any computational representation believed to be common to all members of a particular domain family can be used. This representation, in conjunction with appropriate searching software, should optimally be able to distinguish all true family members from the background noise of unrelated proteins stored in sequence databases. This is a challenging problem, tackled with varying degrees of sophistication by different approaches. At the most basic level, the representation can consist of a simple pattern of amino acids common to a particular domain. Such an approach is found in... 

There are a large number of oilseeds some of them are very important because they yield edible oils. Among them are soybean (Glycine max), rapeseed (Brassica campestris), coconut (Cocos nucifera), and sunflower (Helianthus annuus). In addition to their lipid content, ranging from 20 to 55%, oilseeds often have substantial amounts of protein stored as protein bodies (30% or more v/v) and saccharides stored as cell wall components. Thus, the main subcellular structure consists of protein bodies 5 to 20 pm in diameter, surrounded by a cytoplasmic protein network in which are embedded the oil storage sites (Figure 2.1). These lipid bodies, sometimes referred to as spherosomes, are only 0.2 to 0.5 pm in diameter and are connected through a thin envelope. 

Because the capacity of the body to change carbohydrate and protein stores is extremely limited, the energy balance is really fat balance, and this could be a key to the metabolic syndrome. Although saturated fats are still the main dietary factors that induce a cascade of disregulation at multiple metabolic sites, more and more attention is being focused on effect of monoenoic FA and the appropriate balance between the n-6 and n-3 classes of PUFA. 

If metabolic fuel becomes available after several days of starvation, the metabolic response is one that reinstates the depleted carbohydrate and protein stores.
