Further, ingestion of specific amino acids could be beneficial.
With limited amino acid intakes, a high intake of the vitamin can improve the ability of the animal to synthesize and interconvert dietary and tissue amino acids so that the limiting amino acid may be used more efficiently.
This protein may play an important role in the absorption and necessary intestinal metabolism of vitamin A.
The relative rates of amino acid absorption from the protein hydrolysate and amino acid mixture varied markedly with concentration, demonstrating that the global hypothesis that peptides confer an advantage in amino acid absorption in vivo is too simple.
It also plays an important role in the mediation of the inhibitory effect of intestinal amino acids on their own absorption at the level of proximal or distal segment.
Physiologic rather than pharmacologic doses of vitamin A can be used to study vitamin A absorption.

In an amino acid mixture amino acids may inhibit the absorption of one another if they share a common transport system.
The results indicate that absorption is significantly more rapid after the ingestion of the amino acids than after the dipeptide.

What is the effect of amino acids on feed intake of pigs?4 answersAmino acids have been shown to have varying effects on feed intake in pigs. Lysine (Lys) significantly reduced feed intake, particularly during the first 30 minutes and up to 2.5 hours post-gavage. Similarly, leucine (Leu) and isoleucine (Ile) also decreased feed intake up to 3 hours post-gavage. Glutamine and glutamate stimulated the production of acetate and butyrate, while arginine and lysine increased propionate levels. However, phenylalanine and glucose had no significant impact on feeding behavior. The impact of amino acids on feed intake is mediated through the release of gut hormones, such as cholecystokinin and glucagon-like peptide 1. Overall, the effects of amino acids on feed intake in pigs are complex and depend on the specific amino acid and its interaction with gut hormones and feeding behavior.
How does vitamin B12 absorption work?4 answersVitamin B12 absorption involves multiple steps and carriers. After ingestion, vitamin B12 becomes complexed to haptocorrin in the stomach to prevent acid destruction. In the duodenum, pancreatic proteases hydrolyze haptocorrin, allowing vitamin B12 to bind to intrinsic factor. This complex then traffics to the cubulin receptor in the ileum, facilitating entry into the enterocyte. Once inside the enterocyte, vitamin B12 binds to transcobalamin II and circulates systemically to other cells. Impairment of any step in this process can lead to vitamin B12 deficiency, which can have neurological, hematological, and gastrointestinal effects. Causes of malabsorption include inherited disorders, such as intrinsic factor deficiency and Imerslund-Grasbeck syndrome, as well as other conditions like celiac disease and pancreatic insufficiency. The absorption of vitamin B12 is a complex process that is essential for maintaining overall health.
Which is aminoacid metabolism?5 answersAmino acid metabolism is a complex process involving the exchange and metabolism of amino acids between different organs in the body. It plays a crucial role in various physiological processes, including gene expression, vasodilation, immune response, and energy homeostasis. Tumor cells, in particular, rewire their metabolic pathways to meet their increased nutritional demands, and alterations in amino acid metabolism are one way they satisfy these demands. Amino acids are not only building blocks of proteins but also serve as intermediate metabolites fueling multiple biosynthetic pathways. Reprogrammed amino acid metabolism is a common feature in cancer cells and is closely linked to redox balance and epigenetic regulation. Understanding amino acid metabolism is important for addressing disease states and developing targeted therapeutic approaches.
