Proteinogenic amino acids are amino acids that are incorporated biosynthetically into proteins during translation from RNA. The word "proteinogenic" means "protein creating". Throughout known life, there are 22 genetically encoded (proteinogenic) amino acids, 20 in the standard genetic code and an additional 2 (selenocysteine and pyrrolysine ...
There are 20 universal genome-encoded, proteinogenic amino acids. ... Pages in category "Proteinogenic amino acids" The following 24 pages are in this category, out ...
The 21 proteinogenic α-amino acids found in eukaryotes, grouped according to their side chains' pK a values and charges carried at physiological pH (7.4) 2-, alpha-, or α-amino acids [21] have the generic formula H 2 NCHRCOOH in most cases, [b] where R is an organic substituent known as a "side chain". [22]
In this area of research, the 20 encoded proteinogenic amino acids are referred to as standard amino acids, or alternatively as natural or canonical amino acids, while the added amino acids are called non-standard amino acids (NSAAs), or unnatural amino acids (uAAs; term not used in papers dealing with natural non-proteinogenic amino acids ...

The genetic code encodes in all organisms 20 canonical amino acids that are used for protein biosynthesis. In rare cases, special amino acids such as selenocysteine or pyrrolysine can be incorporated by the translational apparatus in to proteins of some organisms. [8] Together, these 20+2 Amino Acids are known as the 22 Proteinogenic Amino ...
The Alanine World Hypothesis postulates that the evolution of the genetic code (the so-called GC phase [87]) started with only four basic amino acids: alanine, glycine, proline and ornithine (now arginine). [88] The evolution of the genetic code ended with 20 proteinogenic amino acids.
