The various alpha amino acids differ according to R group, which is attached to their alpha carbon and these can vary in size from just one hydrogen atom as in glycine to large heterocyclic groups such as in tryptophan. Amino acids are important as building blocks of proteins that are linear...

Finally, the overall structure of the cyclization domain of TiCGSCy was found to be similar to those of β-1,2-glucanases in phylogenetically different groups. Meanwhile, the identified catalytic residues indicated clear differences in the reaction pathways between these enzymes. Overall, we propose...

some polar or charged residues on the hydrophobic face of AMPs can promote the formation of pores by drawing lipid-head groups into the bacterial membrane. Pore formation is often connected to a local change in membrane thickness9. Under the carpet model, peptides are accumulated on the bacteria...
Functionalmonomersare those showing particularly reactive side-chain groups that can be used in order to synthesize more complex vinyl compounds, such as macromonomers; or to improve the functionality of preformed polymer chains. Moreover, these monomers and polymers can be used to trim some polymeriz...
amino acid of each pair is favored at that position. In this assay, the cleavage of HMW-HA by hyaluronidase is recorded by monitoring UV absorbance at 232 nm, which increases with the formation of an unsaturated carbon-carbon bond in the β–D-glucuronic acid moiety at the cleavage site...
Unlike in a helix, in an extended chain the main-chain oxygen and amide are not fully saturated with internal hydrogen bonds. Therefore, an extended chain can supply main-chain carbonyl oxygen and amide to coordinate Na+ together with charged and polar side-chains from surrounding amino acids ...
