Carnosine (beta-alanyl-L-histidine) is a dipeptide molecule, made up of the amino acids beta-alanine and histidine. It is highly concentrated in muscle and brain tissues. [citation needed] Carnosine was discovered by Russian chemist Vladimir Gulevich. [1] Carnosine is naturally produced by the body in the liver [2] from beta-alanine and histidine.
Carnosine is a dipeptide composed of beta-alanine and histidine, and is found in skeletal muscle and cells of the nervous system. [6] This disorder results in an excess of carnosine in the urine , cerebrospinal fluid , blood , and nervous tissue . [ 7 ]
In a large sample of adults of all ages and both sexes, the figure for water fraction by weight was found to be 48 ±6% for females and 58 ±8% water for males. [8] Water is ~11% hydrogen by mass but ~67% hydrogen by atomic percent , and these numbers along with the complementary % numbers for oxygen in water, are the largest contributors to ...
The researchers said that although carnosine is rapidly degraded by enzymes in the body, it could potentially be an initial treatment for prostate cancer if a constant slow release mechanism is used.
Carnosine synthase (EC 6.3.2.11) is an enzyme that catalyzes the chemical reaction ATP + L-histidine + beta-alanine ⇌ {\displaystyle \rightleftharpoons } ADP + phosphate + carnosine The 3 substrates of this enzyme are ATP , L-histidine , and beta-alanine , whereas its 3 products are ADP (previously thought to form AMP [ 1 ] ), diphosphate ...
Lactose is a disaccharide found in animal milk. It consists of a molecule of D-galactose and a molecule of D-glucose bonded by beta-1-4 glycosidic linkage.. A carbohydrate (/ ˌ k ɑːr b oʊ ˈ h aɪ d r eɪ t /) is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water) and thus with the empirical formula C m ...
Carbohydrates, which store energy in a form that can be used by living cells. [2] Lectin, for binding proteins. [28] Monosaccharide, simple sugars, including glucose and fructose. [2] Disaccharides, sugar soluble in water, including lactose, maltose, and sucrose. [2] Starch, made of amylose and amylopectin, plants energy storage. [2]
Carnosine and metabolic derivatives of carnosine, including NAC, are found in a variety of tissues but particularly muscle tissue. [1] These compounds have varying degrees of activity as free radical scavengers. [1] It has been suggested that NAC is particularly active against lipid peroxidation in the different parts of the lens in the eye. [3]
