Dipeptide absorption in man [PDF]

Gut, 1972
A quantitative perfusion method has been used to study intestinal absorption of two dipeptides-glycyl-glycine and glycyl-l-alanine-in normal subjects. In each case, the constituent amino acids were absorbed faster when presented as dipeptides than as free amino acids, suggesting intact dipeptide transport. During absorption constituent amino acids were

The New Dipeptide TSPO Ligands: Design, Synthesis and Structure–Anxiolytic Activity Relationship

Molecules, 2020
The translocator protein (TSPO, 18 kDa) plays an important role in the synthesis of neurosteroids by promoting the transport of cholesterol from the outer to the inner mitochondrial membrane, which is the rate-limiting step in neurosteroidogenesis ...

L-Glutamine peptides as a means of accelerated rehydration under intense physical activity in athletes

Спортивная медицина: наука и практика, 2020
This review is devoted to the theory and practice of the use of glutamine dipeptides in sports. The pathway of L-Glutamine dipeptides is described from the moment of oral intake and entering the intestine to inclusion in intracellular metabolic processes

Self-Assembly of the Dipeptide L-Alanyl-L-Phenylalanine under the Action of Methanol Vapor with the Formation of Micro- and Nanostructures

Учёные записки Казанского университета: Серия Естественные науки, 2023
The mechanism of self-assembly by short-chain peptides (oligopeptides) – the process by which their molecules spontaneously form an ordered structure – has received much attention recently.
