A series of N-aryl phthalimides was prepared through the reaction of phthalic acid with aryl amines (anilines) in ethanol under mild condition with L-proline
as catalyst at room temperature.
is an important amino acid in terms of its protective effect against freezing injury.
Proline content was calculated using L-proline
(Sigma) as a standard curve.
Previous study has shown that L-proline
can improve small-intestinal morphology in the weanling piglet (Wu et al., 2011).
Also, with addition of L-valine and L-proline
, Rap titre was dropped down to be around the third of that in control sample.
For successful callus induction and growth rate L-proline
0.5 mg L-1 and caesine hydrolysate 0.1 mg L-1 were used in N6 callus culture media.

catabolism gene cluster of Aspergillus nidulans" Molecular Microbiology, vol.
While most of our strains (60-78%) were still positive and 18-28% were weakly positive to melibiose, monomethyl succinate, D-alanine, L-alanine, L-alanyl-glycine, and glycerol, only some were positive to glycyl-L-glutamic acid (41% strongly and 30% weakly), cisaconitic acid (20% strongly and 36% weakly), lactic acid (17% strongly and 50% weakly), L-proline
(14% strongly and 21% weakly), L-aspartic acid (27% strongly and 23% weakly), hydroxy L-proline
(34% strongly and 31% weakly), and glucose-6-phosphate (33% strongly and 36% weakly), and the reaction to [beta]-methyl D-glucoside and inosine was predominantly negative and positive with only 1% and 3% of the strains, respectively.
africana doesn't produce chlamydospores, doesn't grow at 42[degrees] C, tests negative for L-proline
aminopeptidase activity, and grows in rough colonies on bird seed agar, instead of smooth ones.
The role of L-proline
in response to osmotic stress in Salmonella typhimurium: Selection of mutants with increased osmotic tolerance as strains which overproduce proline.
It's all thanks to L-Proline
, a Decleor staple, but they've doubled concentration for instant and long-term results.
cis-4-Hydroxy-L-proline is a kind of amino acid which is hydroxylated in the 4-position of L-proline
, and is believed to have potential as a raw material for pharmaceutical and cosmetic products.
Estradiol-17[beta] ([E.sub.2]), sesame oil, lipopolysaccharide (LPS) from Escherichia coli 055:B5, L-arginine, L-citrulline, L-ornithine monohydrochloride, L-proline
, SDMA [[N.sup.G], [N.sup.G]-dimethyl-L-arginineinine di(p-hydroxyazobenzene-p'sulfonate) salt], and BSA were obtained from Sigma Aldrich.
For example, Anti Age 40+ includes a collagen formula that consists of vitamin C and two amino acids, L-lysine and L-proline
, to support collagen production.
