Proline: a multifunctional amino acid.
Proline accumulates in many plant species in response to environmental stress. Although much is now known about proline metabolism, some aspects of its biological functions are still unclear. Here, we discuss the compartmentalization of proline biosynthesis, accumulation and degradation in the cytosol, chloroplast and mitochondria. We also describe the role of proline in cellular homeostasis, i...
متن کاملMolecularly imprinted photonic crystals for the direct label-free distinguishing of L-proline and D-proline.
Novel molecularly imprinted photonic crystals (IPCs) for the highly sensitive label-free detection of L-proline and for the chiral recognition of L/D-proline were reported. A series of L-proline imprinted polyacrylamide photonic crystals (PAM-LPIPCs) and poly(acrylamide-co-acrylic acid) photonic crystals (PAM-co-AA-LPIPCs) were fabricated via the in situ polymerization of polystyrene opal. The ...
متن کاملSynthesis of Chiral Thiourea-Phosphine Organocatalysts derived from L-Proline
A novel class of thiourea-phosphine was prepared from L-Proline as a chiral renewable resource. The original structure of the chiral framework offers an interesting potential to the construction of bifunctional organocatalysts for asymmetric transformations.
متن کاملEpimerization of trans-4-hydroxy-L-proline to cis-4-hydroxy-D-proline during acid hydrolysis of collagen.
1. trans-4-Hydroxy-r,-proline is epimerized to &+hydroxy-n-proline under the conditions generally used for the hydrolysis of proteins for analyses of amino acids. 2. The cis epimer elutes from a column of UR-30 resin on a Beckman amino acid analyzer at the same time as threonine and hence would be undetected. 3. About 8% of the trans-4-hydroxy-L-proline in collagen can be epimerized to c&4-hydr...
متن کاملSynthesis, Characterization and Biological Activity of Pure and Metal Ions Doped L-Proline Amino Acid
Alkali, Alkaline earth and transition metal ions doped L-proline single crystals were grown by solution growth technique. Due to variation in the nature of dopant, there is a modification in the growth habit, nonlinear optical property and mechanical hardness of the doped crystals. Fourier transform infrared (FTIR) spectra reveal strong absorption bands occur due to the presence of L-proline. U...
