Jul 20, 2019 · Chart Key: NON-ESSENTIAL ESSENTIAL Note: This chart only shows those amino acids for which the human genetic code directly codes for. Selenocysteine is often referred to as the 21st amino acid, but is encoded in a special manner. In some cases, distinguishing between asparagine/aspartic acid and glutamine/glutamic acid is difficult.

The amino acids below all have a side chain that then makes them to be hydrophobic. This property makes them “water fearing” or unable to dissolve in water. Alanine(Ala) is the first hydrophobic amino acid, and it has low reactivity. This property allows for alanine to create an elongated structure that is equally flexible and stretch resistant. Va...
The amino acids below all have side chains that are polar neutral. This means that their side chains are neither acidic nor basic. Asparagine (Asn) is responsible for removing ammonia (a toxic chemical) from our bodies. Glutamine (Gln) is the most abundant amino acid in our bodies, and it performs several functions. It is responsible for regulating...
Aspartic acid (Asp) is water soluble, which then allows it to be near the active sites of enzymes. Glutamic acid (Glu) is similar to aspartic acid and is highly soluble in water.
Arginine (Arg) is produced when proteins are digested within our bodies, and it is converted into nitric oxide (responsible for relaxing blood vessels). Histidine (His) within proteins acts as both a proton acceptor and donor. Due to this property, histidine can combine into enzymes involved in the metabolism of proteins, carbohydrates, and nucleic...
Cysteine (Cys) is able to form disulfide bridges between to peptide chains and also form loops within a singular chain. Glycine (Gly) is unreactive when it is in proteins. The biosynthesis of serine (amino acid), purines, heme (part of hemoglobinfound in the blood), and also glutathione (coenzyme) all require glycine. Proline (Pro) is made from glu...
