Uptake of α-aminoisobutyric acid in placental slices at term
American Journal of Obstetrics and Gynecology, 1967Abstract Protein synthesis in the placenta has not been extensively studied despite evidence for the presence of all the mechanisms for active formation. The present study characterizes the amino acid uptake in term placental slices from normal pregnancies using the model amino acid, α-aminoisobutyric acid.

Synthesis of [11C-methyl]-α-aminoisobutyric acid (AIB)
Nuclear Medicine and Biology, 1996Alpha-aminoisobutyric acid (AIB) labeled with the cyclotron-produced, positron-emitting radionuclide 11C has been synthesized with the label in the alpha-methyl group. Our previously published synthesis of [11C] AIB in the carboxyl position from [11C] HCN requires a rigorous quality assurance program to ensure that the concentration of cyanide in the ...

Hydrophobic channels in crystals of an α-aminoisobutyric acid pentapeptide
Biochemical and Biophysical Research Communications, 1981Abstract The crystal structure of the pentapeptide p-toluene-sulfonyl-(α-aminoisobutyryl) 5 -methyl ester (Tosyl-(Aib) 5 -OMe) has been determined in the space group P I . Pentapeptide molecules are folded in the 3 10 helical conformation and packed together, so as to yield a hydrophobic channel with a minimim diameter of 5.2 A.

alpha-Aminoisobutyric acid accumulation of the toad's (Bufo marinus) cornea and lens is inhibited by 4,4'-diisothiocyano-2,2'-stilbenedisulfonic acid. This effect is seen at pH 8.4; at pH 7.4 a small increase in aminoisobutyric acid uptake was observed.
