Serine is generally classified as a nutritionally nonessential (dispensable) amino acid, but metabolically, serine is indispensible and plays an essential role in several cellular processes. Serine is the major source of one-carbon units for methylation reactions that occur via the generation of S-adenosylmethionine.

What is the R group found in alanine?
methyl group CH3The R side chain in alanine is the methyl group CH3.
Is serine polar neutral?
Serine, threonine, glutamine, and asparagine are polar but neutral (uncharged) amino acids. These side chains can form multiple hydrogen bonds, so they prefer to project into the aqueous phase.

What is the role of serine in the body?
Serine's side-chain structure, the component of amino acid that makes is unique, is CH3O. Its structure is polar, giving it hydrophilic properties. There are many important roles that serine plays in biological processes. For example, it is vital in metabolism, playing an important role in the formation of enzymes. It is also a signaling chemical in the brain, specifically transmitting information related to memory. Supplemental serine has even shown potential in fighting schizophrenia or Lou Gehrig's disease. Serine is obtained from synthesis within the body and it can also be consumed through meat, soy products, dairy and plants, such as peanuts. Without serine many metabolites, including the building blocks of genetic code and chemicals vital to life would not be formed.
What makes serine so important?
What makes serine so important and versatile is its structure. In general, all amino acids have the same structure: an amino group attached to a hydrogen, a carboxyl group and a side chain group, all connected to a central carbon. The amino and carboxyl groups and central carbon are considered the amino acid backbone. That backbone is the same in all amino acids. It is the side chain that is specific to each amino acid. It is this side chain that distinguishes each amino acid from the others. The side chain group is shown by R when diagramming amino acids, leading scientists to call the side change the R group. The specific structure of serine is indicative of its chemical formula, C3H7NO3. The R group structure, CH3O, attaches to the central carbon of the amino acid back bone. Remember, that's the carbon along with the amino and carboxyl groups. Serine is polar in nature. That means that the serine molecule is both positively and negatively charged. This polar characteristic makes serine hydrophilic, or water-loving.
