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.
exists and is an alternate of . An R group is the chemical group attached to the alpha carbon in an amino acid. In proteins all amino acids have the same basic structure and vary only in their R group. There are 20 standard amino acids found in proteins, which all have different R groups. For example an amino acids with Hydrogen from its R group is glycine, and one carbon with 3 hydrogens (a methyl group) is the R group for alanine. An R group is the chemical group attached to the alpha carbon in an amino acid.
