Why is it Polar? There are certain criterions that each chemical must fulfill in order to be considered polar and since ammonia passes those criterions, it falls among the list of polar chemicals on earth. Primarily though, one can consider that the polarity of ammonia is due to the fact ...
Name one amino acid which is often found in transmembrane helices. What is the length of a helical protein consisting of 500 amino acids? Which of the following amino acids has a polar side chain? Identify the amino acid that is a catabolic precursor of the given -keto acid. ...
The first morphological event is an asymmetric cell division by forming a polar septum, which creates a larger mother cell, and a smaller forespore generates a smaller forespore. Next, after the completion of DNA segregation, the mother cell engulfs the forespore. Calcium dipicolinic acid (Ca-...
To span the lipid bilayer, an a-helix must be composed by a minimum of about 20 amino acids, mainly hydrophobic.24 The purported transmembrane domain of Hax1 consists in an a-helix of 16 amino acids, 4 of which are charged and 1 is polar (RPPALDDAFSILDLFL), which could not form a...

The deduced amino acid sequence of Sm25 shows a short C-terminal hydrophobic domain between residues 163 and 180, containing six uncharged polar amino acids and followed by a Lys181-Ser192 dipeptide. We were interested in whether or not this marginal C-terminal amphiphilic domain is responsible...
Two amino acid ionic liquids (AAILs) were investigated by molecular dynamics simulation to get effect of polar group at bulk of liquid and adsorb layer of electric double layer. Hydrogen bond plays an important role in this evaluation. Polar group changed hydrogen bond site of the pure bulk. ...

Intriguingly, the large unstructured region encompasses two functional domains: a polar amino acid rich domain and a C-terminal domain. These findings suggest that PQBP-1 belongs to the family of intrinsically unstructured/disordered proteins. Furthermore, the binding of the target molecule U5-15kD...
