Since ancient times, seaweeds have been employed as source of highly bioactive
secondary metabolites that could act as key medicinal components. Furthermore, research …

Taurine (a sulfur-containing β-amino acid), creatine (a metabolite of arginine, glycine and
methionine), carnosine (a dipeptide; β-alanyl-l-histidine), and 4-hydroxyproline (an imino …

As a functional amino acid (AA), L-arginine (Arg) serves not only as a building block of
protein but also as an essential substrate for the synthesis of nitric oxide (NO), creatine …

Glycine, proline, and hydroxyproline (Hyp) contribute to 57% of total amino acids (AAs) in
collagen, which accounts for one-third of proteins in animals. As the most abundant protein …

A protein consists of amino acids (AA) linked by peptide bonds. Dietary protein is hydrolyzed
by proteases and peptidases to generate AA, dipeptides, and tripeptides in the lumen of the …

Simple Summary The first week after hatch is the most challenging period in the life of
broilers. The digestive tract of the newly hatched chick is immature and must undergo …

Recent years have witnessed a growing interest in the role of peptides in animal nutrition.
Chemical, enzymatic, or microbial hydrolysis of proteins in animal by-products or plant …

We analyzed the composition of amino acids (AAs) in oligopeptides, proteins, and the free
pool, as well as creatine, agmatine, polyamines, carnosine, anserine, and glutathione, in …

Abstract α-Lactalbumin is a whey protein that constitutes approximately 22% of the proteins
in human milk and approximately 3.5% of those in bovine milk. Within the mammary gland, α …

The recent years have witnessed growing interest in biochemistry, physiology and nutrition
of amino acids (AA) in growth, health and disease of humans and other animals. This results …
