The polymer micelle medicine carrier is composed of amphiphilic block polymer and amino acid. The amphiphilic block polymer is diblock polymer or triblock polymer and preferably is mPEG-PDLLA. The amino acid is chosen from 20 common amino acids. The weight ratio of amphiphilic polymer to amino ...
Polymers are materials made from large molecules composed of many repeating units. Naturally occurring polymers include starch, which is made up of many repeating units of the sugar glucose, and proteins, which are long chains of amino acids. Most polymers are organic, using carbon bonds as their...
Pentameric synthetic polypeptides with elastin-like repeating units of amino acids valine–proline–glycine–valine–glycine (VPGVG) have been reported that exhibit inverse transition temperature. Almost all of the elastin-like polypeptides (ELPs) (Figure 1.3) are derived from the sequence Val/Ile–...
They are composed of a sugar, a phosphate, and a nitrogenous base. What are the subunits (monomers) of nucleic acids such as DNA and RNA? A) sugar B) hydrogen bonds C) nucleotides D) amino acids What are the monomers of DNA and RNA? ...
To investigate local interactions in tripeptide sequences composed of amino acids having aromatic side chains, conformational analysis of N-acetyl-N′-methylamide of the Phe-Phe-Phe tripeptide was theoretically carried out using the conformational energy
摘要: A novel chiral ionic polymer exhibits high fluorescence enantioselectivity towards alpha-amino acid anions, and its solution appears bright green upon addition of (L)-alpha-amino acid anions, which can be clearly observed by the naked eye for direct visual enantioselective recognition....
Each sequence was first reduced into four types of pseudo-residue: hydrophilic, hydrophobic, very hydrophobic and charged, on the basis of the respective side-chain hydrophobicity of amino acids (Extended Data Table 1)17. Initial sequence analysis was also tested using two or eight pseudo-residues...
