Part Descriptions

LP15504-1   Citrulline
Citrulline is an alpha amino acid, produced from ornithine and carbamoyl phosphate during the urea cycle. Its name is derived from citrullus, the Latin word for watermelon, from which it was first isolated. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.

LP32175-9   Tyrosine
Tyrosine (from the Greek tyros, meaning cheese, as it was first discovered in cheese[ citationneeded ]), 4-hydroxyphenylalanine, or 2-amino-3(4-hydroxyphenyl)-propanoic acid, is one of the 20 amino acids that are used by cells to synthesize proteins. It has a phenol side chain with a hydroxyl group. Upon the location of the hydroxyl group, there are three structural isomers of Tyr, namely para-Tyr (p-Tyr), meta-Tyr (m-Tyr) and ortho-Tyr (o-Tyr). Enzymatically, only the first isomer (p-Tyr) is produced from L-Phe by the Phe-hydroxylase enzyme. The other two isoforms, m-Tyr and o-Tyr can be produced as a consequence of free radical attack on Phe in states with increased oxidative stress.

LP32175-9   Tyrosine
A non-essential amino acid. In animals it is synthesized from PHENYLALANINE. It is also the precursor of EPINEPHRINE; THYROID HORMONES; and melanin. Source: National Library of Medicine, MeSH 2006
