A dose 210 mg of carnosine only lasts about 5 hours in the blood before begin degraded by carnosinase
These authors have hypothesized that CNP is a non-secreted enzyme and differs from those secreted such as serum carnosinase
and anserinase, with a limited expression, and that arise by the effect of the second duplication of the gene once the urochordates separated from the vertebrate to evolve as secreted enzymes.
Porem, a suplementacao de carnosina oral e um metodo ineficiente para elevar os niveis de carnosina muscular nos seres humanos (Gardner e colaboradores, 1991) devido ao fato de nao ser absorvida em sua forma integra, ja que no aparelho digestorio esta presente a enzima carnosinase
que rapidamente hidrolisa este dipeptideo, como mostra a Figura 1 (Sale, Saunders e Harris, 2010; Hobson e colaboradores, 2012).
They found that acute carnosine exposure altered mitochondrial function and it is important for future studies of carnosinase
deficiency, a disease that affects several human tissues .
The localization of the gene on chromosome 18q22.3-23 was the first identified genetic loci in Turkish DKD patients of T2DM , which is in the region of carnosinase
genes, and the polymorphism of relevant genes of carnosine dipeptidase (CNDP)1 and 2 was later proved to be related with the progression of DKD in T2DM patients [5,6].
Due to individual differences in plasma carnosinase
levels, there is significant variability in response to carnosine ingestion.
In addition, carnosine is not addictive; there is no danger of overdose, and it does not accumulate in the organism during longterm administration because its surplus is cleaved by the enzyme carnosinase
into amino acids that are easily eliminated from the organism .
A administracao direta de carnosina nao aumenta os seus estoques musculares, pois ela e rapidamente hidrolisada pela enzima carnosinase
, presente no plasma humano (Asatoor e colaboradores, 1970; Perry e colaboradores, 1967).

levels in aging brain: redox state induction and cellular stress response," Antioxidants and Redox Signaling, vol.
A new test, which compares he levels of the chemicals enolase (which brain cells release when they die) and carnosinase
(production halts because of brain cell death) in the blood, may help families of stroke victims prepare for the future.
That's because the amount of carnosine in meat is rapidly degraded by carnosinase
enzymes in your body.
initially postulated that the CNDP1 gene on chromosome 18q22.3-q23, encoding serum carnosinase
(CN-1), is a susceptibility gene for dN in type 2 diabetes mellitus (T2DM) patients .
