Biological value is determined based on this formula. [4] [5] BV = ( N r / N a) * 100. Where: N a = nitrogen absorbed in proteins on the test diet N r = nitrogen incorporated into the body on the test diet. However direct measurement of N r is essentially impossible. It will typically be measured indirectly from nitrogen excretion in urine. [6]
Vegetables. Wolffia arrhiza, dry weight: 40; Nori seaweed, dried sheets: 5.81; ready-to-eat green vegetables: 0.33 to 3.11; ready-to-eat starchy tubers: 0.87 to 6.17 . high scores: home-prepared potato pancakes 6.17; French fries 3.18-4.03
Whey is the type of protein contained in many popular brands of protein supplements and is preferred by many bodybuilders because of its high biological value (BV) and quick absorption rates. Whey protein also has a bigger effect than casein on insulin levels, triggering about double the amount of insulin release. [ 69 ]
The PDCAAS value is different from measuring the quality of protein from the protein efficiency ratio (PER) and the biological value (BV) methods. [3] The PER was based upon the amino acid requirements of growing rats, which differ significantly from those of humans.
As a value, NPU can range from 0 to 1 (or 100), with a value of 1 (or 100) indicating 100% utilization of dietary nitrogen as protein and a value of 0 an indication that none of the nitrogen supplied was converted to protein. Certain foodstuffs, such as eggs or milk, rate as 1 on an NPU chart.
In biology, the biological cost or metabolic price is a measure of the increased energy metabolism that is required to achieve a function. Drug resistance in microbiology, for instance, has a very high metabolic price, [ 1 ] especially for antibiotic resistance .
It is the largest Wikipedia written in any Slavic language, surpassing its nearest rival, the Polish Wikipedia, by 20% in terms of the number of articles and fivefold by the parameter of depth. [4] In addition, the Russian Wikipedia is the largest Wikipedia written in Cyrillic [5] or in a script other than the Latin script. In April 2016, the ...
