Part Descriptions
LP18446-2 N-acetyltyrosine
N-acetyl-L-tyrosine (NAT) is an acetylated derivative of the amino acid L-tyrosine. As a supplement, NAT is commonly used in place of tyrosine, which is less stable and less soluble in water. PMID: 14621123 It is used as a protein supplement to treat phenylketonuria (PKU).
NAT is also used for other conditions such as depression, attention deficit disorder (ADD), attention deficit-hyperactivity disorder (ADHD), narcolepsy, and improving alertness following sleep deprivation.

LP32035-5 Creatinine
Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.
