It is well known that endogenous bioactive proteins and peptides play a substantial role in
the body's first line of immunological defence, immune-regulation and normal body …

Intestinal catheters have been used for decades in human nutrition, physiology,
pharmacokinetics, and gut microbiome research, facilitating the delivery of compounds …

Background Whey protein and zein are of nutritional interest due to their high leucine
content, but little data are available on their amino acid (AA) ileal digestibility. Objective This …

Metabolism of protein by gut bacteria is potentially detrimental due to the production of toxic
metabolites, such as ammonia, amines, p-cresol, and indole. The consumption of prebiotic …

Simple Summary As variations in the determination of basal endogenous losses can affect
the estimation of the nutritional value of diets, this study used a proteomics approach to …

Bacterial metabolites are one of the main mechanisms of host-microbiota interactions in the
gut. Acetate, propionate, and butyrate, also known as short-chain fatty acids (SCFA), are the …

ABSTRACT Background Endogenous amino acids (AAs) contribute to terminal ileal digesta
and must be corrected for in determining coefficients of true ileal digestibility. Such estimates …

A recently proposed paradigm suggests that, like their dietary counterparts, digestion of
gastrointestinal endogenous proteins (GEP) may also produce bioactive peptides. With an …

Dietary amino acids (AA) supplied as protein or in free form are not only digested and
absorbed at different rates but can also induce differences in the intestinal physiology of …

This study was conducted to assess the influence of dietary protein content in poultry when
using the 15N-leucine single-injection method to determine endogenous amino acid losses …
