You don't actually have to navigate to the folder to list the files within it. You can simply specify the path as part of the ls command as shown below. ls /path/to/file. By default the files and folders will be listed in columns across the screen and all you will see is the filename.
Alanine (abbreviated as Ala or A; encoded by the codons GCU, GCC, GCA, and GCG) is an Î±-amino acid that is used in the biosynthesis of proteins.
beta-Alanine Î²-Alanine (or beta-alanine) is a naturally occurring beta amino acid, which is an amino acid in which the amino group is at the Î²-position from the carboxylate group (i.e., two atoms away, see Figure 1). The IUPAC name for Î²-alanine is 3-aminopropanoic acid. Unlike its counterpart Î±-alanine, Î²-alanine has no stereocenter.
