sarcosine

 [sahr´ko-sēn]
an amino acid occurring as an intermediate in the metabolism of choline in the kidney and liver; it is normally not detectable in human blood or urine.

sar·co·sine (Sar),

(sar'kō-sēn),
N-Methylglycine; an intermediate in the metabolism of choline; it can donate a methyl group to tetrahydrofolate, yielding N5,N10-methylenetetrahydrofolate; demethylation by sarcosine dehydrogenase yields formaldehyde, glycine, and a reduced acceptor; elevated in certain inherited disorders.

sarcosine

(sär′kə-sēn′, -sĭn)
n.
An amino acid made synthetically or formed naturally during the decomposition of creatine.

The bacterial cells in the agarose plugs were lysed by treatment with lysis solution (1 mg of lysozyme per mL, 0.4% N-sodium lauryl sarcosine, 0.2% Na-deoxycholate, 10 mM Tris [pH 7.2], 50 mM NaC1) at 37 [degrees] C overnight and treated with proteinase K at 50 [degrees] C overnight.
This method is based on the same reaction sequence as the Creatinine-PAP (phenol aminophenazone) method (29) consisting of 4 consecutive enzymatic steps via creatininase, creatinase, sarcosine oxidase, and peroxidase, but using a different chromophore (2,4,6-triiodo-3-hydroxybenzoic acid) and a modified detergent composition.

Biotin was conjugated to a sarcosine linker that served two functions: (a) it provided the moiety for stable-isotope introduction in the synthesis of internal standards, and (b) it blocked the action of the enzyme biotinidase (15), which is present in biological fluids and could cleave the biotin handle off the product conjugates.
