This amino acid competes with Tyrosine and Tryptophan in crossing the blood-brain barrier. Amino acids are crystalline solids which usually are water soluble and only sparingly dissoluble in organic solvents. Their solubility depends on the size and nature of the side chain. Amino acids have very high melting points, up to 200-300°C. Their other properties varying for each particular amino acid. 20 Amino Acids and their Functions 1999-05-04 H C COOH COOH H an L-amino acid (S) configuration R R FIGURE 24-2 Almost all the naturally occurring amino acids have the (S) configuration.

It was obtained from protein found in asparagus juice (hence the name).

Amino acids with an amide on the side chain do not produce basic solutions i.e. asparagine and glutamine. Neutral Side Chains: Since an amino acid has both an amine and acid group which have been neutralized in the zwitterion, the amino acid is neutral unless there is an extra acid or base on the side chain.

The Twenty Amino Acids The twenty amino acids (that make up proteins)each have assigned to them both three-letter (can be upper or lower case) and one-letter codes (upper case).

One of the amino acids contained most abundantly in the body. Plays a role in protecting the stomach and intestinal tract.

Additional amino acids are added in the same way, by formation of peptide bonds between the free carboxyl on the end of the growing chain and the amino group of the next amino acid in the sequence. A chain made up of just a few amino acids linked together is called an oligopeptide (oligo=few) while a typical protein, which is made up of many amino acids is called a polypeptide (poly=many). This amino acid is one of the three major Branched-Chain Amino Acids.

Glycine as an Amino Acid. Colorless and odorless, glycine (or aminoacetic acid) is the simplest amino acid found in nature because of its single hydrogen side chain. But its functions are anything but simple: glycine is an essential component of protein synthesis, proper enzyme function, and lipid digestion and absorption. Wang2013 The failure to obtain enough of even 1 of the 10 essential amino acids has serious health implications and can result in degradation of the body’s proteins. Muscle and other protein structures may be dismantled to obtain the one amino acid that is needed.
