Research Progress on Evaluation Method of Functional Characteristics of Food-Derived Peptides, Molecular Structure-Activity Relationship and Absorption and Metabolism Mechanism(食源性肽的功能特性评价方法、分子构效关系及吸收代谢机制) [PDF]

Shipin kexue jishu xuebao, 2023
Peptides were compounds with intermediate molecular structures between amino acids and proteins, having numerous nutritional properties including easy absorption, low osmotic pressure, low immunogenicity, and high tissue permeability.

Dysbiosis of Gut Microbiota and Lipidomics of Content Induced by Dietary Methionine Restriction in Rice Field Eel (Monopterus albus)

Frontiers in Microbiology, 2022
An 8-week feeding trial was conducted using the rice field eel (Monopterus albus) with six isonitrogenous and isoenergetic experimental diets of basic feed supplemented with different levels of methionine (0, 2, 4, 6, 8, or 10 g/kg).

Cysteine residues in the C-terminus of the neutral- and basic-amino-acid transporter heavy-chain subunit contribute to functional properties of the system b0,+-type amino acid transporter [PDF]

Biochemical Journal, 2000
The neutral- and basic-amino-acid-transport glycoprotein NBAT (rBAT, D2) expressed in renal and jejunal brush-border membranes interacts with the b0,+AT permease to produce a heteromeric transporter effecting amino acid and cystine absorption. NBAT mutations result in type I cystinuria.

Identification of the family of aquaporin genes and their expression in upland cotton (Gossypium hirsutum L.)

BMC Plant Biology, 2010
Background Cotton (Gossypium spp.) is produced in over 30 countries and represents the most important natural fiber in the world. One of the primary factors affecting both the quantity and quality of cotton production is water.

Cellular distribution of neutral and basic amino acid transport systems in rabbit ileal mucosa.

The Journal of Physiology, 1981
1. An autoradiographic technique is described whereby the cellular location of tritiated amino acids can be determined following uptake by rabbit ileal mucosa. 2. Stirring solutions in contact with the intestinal mucosa during measurement of rapid influx changes the quantity, but not the distribution, of alanine taken up by the tissue. 3.

Distinguishing transport systems having overlapping specificities for neutral and basic amino acids in the rabbit ileum.

The Journal of Physiology, 1981
1. The kinetic parameters of lysine and alanine uptake by rabbit ileal mucosa have been measured in the presence and absence of Na. 2. Using lysine as an inhibitor of part of alanine uptake in the absence of Na it has been possible to define two mediated systems for alanine entry.

Na+-dependent transport of basic, zwitterionic, and bicyclic amino acids by a broad-scope system in mouse blastocysts.

Journal of Biological Chemistry, 1985
Mouse blastocysts which had been activated from diapause in utero appeared to take up amino acids via a Na+-dependent transport system with novel characteristics. In contrast to other cell types, uptake of 3-aminoendobicyclo [3,2,1]octane-3-carboxylic acid (BCO) by blastocysts was largely Na+ dependent. Moreover, L-alanine and BCO met standard criteria

Na+-independent transport of basic and zwitterionic amino acids in mouse blastocysts by a shared system and by processes which distinguish between these substrates.

Journal of Biological Chemistry, 1988
Preimplantation mouse blastocysts were found to contain at least three mediated components of Na+-independent amino acid transport. The two less conspicuous components seemed to be selective for either cationic or zwitterionic substrates but were not characterized further or examined for multiple transport activities.

Transport properties of a system y+L neutral and basic amino acid transporter. Insights into the mechanisms of substrate recognition.

The Journal of biological chemistry, 2000
The properties of system y(+)L-mediated transport were investigated on rat system y(+)L transporter, ry(+)LAT1, coexpressed with the heavy chain of cell surface antigen 4F2 in Xenopus oocytes. ry(+)LAT1-mediated transport of basic amino acids was Na(+)-independent, whereas that of neutral amino acids, although not completely, was dependent on Na(+), as
