Still, the Home uses the Google Assistant (Google's aptly named digital assistant built into the Home and Android phones like the Pixel -- and now ) to respond to voice commands conversationally, something Google was eager to demonstrate when the Google Home made its initial debut back in May 2016.
Amino acids were the vital molecules that formed in this experiment and supported this hypothesis for the origin of life. An amino acid is a molecule that contains two functional groups, an amine and a carboxylic acid, as shown in Figure 1. In this illustration there is an additional group called the side chain, designated with an R. The variation seen in naturally occurring amino acids arises from differences in this side chain.
About 9 amino acids have non-polar R-groups and are relatively hydrophobic. Another 6 amino acids have strongly polar R-groups which readily attract water molecules. These are hydrophilic amino acids. The remainder, about 5 amino acids, have R-groups which can ionize. At normal cellular pH's these R-groups become electrically charged, making them even more hydrophilic than the polar amino acids. Any of the 20 different amino acids can occur in any position along a polypeptide chain.
