Mechanisms Involved in Kjeldahl Microwave Digestion of Amino Acids

Journal of Agricultural and Food Chemistry, 1997
The high flexibility of open vessel microwave digestion gives one the opportunity to follow the stepwise degradation of amino acids in the presence of H2SO4 and H2O2.

In vitro amino acid digestibility of food proteins as measured by the digestion cell technique

Plant Foods for Human Nutrition, 1989
The digestibility of proteins and individual amino acids of nineteen selected foods was determined by an in vitro assay. Samples were hydrolysed with pepsin for 30 minutes in an acidic medium; the pH was then raised to 7.5 and the mixture poured into the dialysis bag (molecular weight cut-off 1000) of a digestion cell with pancreatin.

Dietary Free Amino Acids and the Gastric Phase of Digestion

Current Pharmaceutical Design, 2014
In the stomach, pre-absorptive perception of food constituents is of particular importance in maintaining secretion and motility that matches the quantity and quality of nutrients. Products of food protein hydrolysis, free amino acids and short peptides, are the most potent chemical stimulants of the gastric phase of digestion. They are recognized by a

ROLE OF THE DIGESTIVE TRACT IN THE UTILIZATION OF PROTEIN AND AMINO ACIDS

Journal of the American Medical Association, 1957
Report to the Counci l The modern renaissance in the study of the chemistry and physiology of the proteins is vigorous, universal, and greatly significant for health. Mulder, the Dutch chemist, was profoundly prophetic in 1839 when he coined the term "protein" to denote the primary importance of these compounds for the animal organism.

[Protein and amino acid metabolism in the digestive tract of growing bulls. 6. Apparent digestibility of the amino acids entering the duodenum and of amino acid from feed].

Archiv fur Tierernahrung, 1986
After studies with young bulls provided with duodenal cannulas the apparent digestibility (AD) of the individual amino acids getting into the duodenum (AAD) was ascertained on the basis of 28 different rations. The AD of the AAD is defined as follows: AAD--AAfaeces/AAD X 100.

[Protein digestibility and absorption of amino acids in various segments of the digestive tract of pigs. 2. Protein and amino acid balances at the end of the small intestine and of the whole digestive tract (apparent and true protein and amino acid digestibility)].

Archiv fur Tierernahrung, 1979
Growing pigs with ileum and ileocecal re-entrant canulae were given 5 different rations (pig fattening feed 1 and 2, rations with dried skim milk, wheat gluten + lysine and wheat + wheat gluten + lysine). The crude protein and amino acid excretion was quantitatively determined with ileum chyme and feces.
