Putrescine and cadaverine4

• They are structurally and biosynthetically related to the diamines putrescine and cadaverine. (wikipedia.org)
• Intestinal bacteria mainly produce putrescine and cadaverine. (foodandnutritionresearch.net)
• The amines assayed (3 mM), except putrescine and cadaverine in the ileum and isoamylamine in the colon, antagonised acetylcholine (ACh, 0.1 mM)-elicited phasic contractions. (foodandnutritionresearch.net)
• The pattern of changes in specific activity of homoagmatine and cadaverine with time when 14C-homoarginine served as the precursor support the conclusion that homoarginine and arginine follow analogous metabolic routes in the biosynthesis of putrescine and cadaverine respectively. (iisc.ac.in)

Tyramine3

• 6 Histamine, tyramine, cadaverine, putrescine, spermine and spermidine are biogenic amines with potential toxicity effects in animals when ingested at high levels. (kemin.com)
• Biogenic amine-producing bacteria are responsible for the production of basic nitrogenous compounds (histamine, cadaverine, tyramine, and putrescine) following the spoilage of food due to microorganisms. (bvsalud.org)
• Cadaverine was detected, but was not influenced by ageing conditions, and tyramine was only detected in some samples after 43 days at −1.7 °C. Individual biogenic amines were not correlated with their precursor amino acids. (gc.ca)

Histamine3

• Some biogenic amine like Histamine, cadaverine and putrescine have been confirmed as useful chemical indicators to estimate bacterial spoilage of foods, particularly fish and fish products, cheese, meat and fermented foods. (ijpsr.com)
• Histamine is toxic at high intakes, while cadaverine and putrescine potentiate the effects of Histamine. (ijpsr.com)
• To estimate bacterial spoilage, biogenic amines, especially putrescine, cadaverine and histamine, have been confirmed as useful chemical indicators 1 . (ijpsr.com)

Polyamines3

• Although test compounds did not significantly deplete intracellular levels of the major polyamines spermine, spermidine, putrecine and cadaverine, definite effects were seen on the activity of key biosynthetic and catabolic enzymes. (gla.ac.uk)
• Both spermine and spermidine are polyamines involved in cellular metabolism. (cimasci.com)
• Spermidine is a precursor to other polyamines, like spermine and thermospermine. (cimasci.com)

Agmatine1

• In shoots, arginine was about 14 times more efficient than ornithine for the synthesis of agmatine, putrescine, spermidine and spermine. (iisc.ac.in)

Polyamine1

• Spermidine, first isolated from semen or sperm, is a water-soluble polyamine ingredient that occurs naturally in all tissues of our human bodies and is also found in many other organisms like animals, plants, and typical dietary foods. (cimasci.com)

Precursor1

• Similar experiments showed that cadaverine was formed at least in part from homoarginine, though lysine was ca 4 times more effective as a precursor. (iisc.ac.in)

Synthetic1

• The color of Spermidine-rich wheat germ extract is white to yellowish powder, while for synthetic spermidine powder, the color is white to off-white. (cimasci.com)

Content1

• We can determine the Spermine content of biomass, click here to learn more about our various biomass analysis methods. (celignis.com)

Natural1

• There are two main ways for obtaining bulk spermidine, one is from natural foods, and the other is from chemical synthesis. (cimasci.com)

Small1

• Spermidine is a small molecule with a molecular weight of 145.25, and a unique CAS Registry Number of 124-20-9. (cimasci.com)

Levels1

• Spermidine levels decrease with age. (cimasci.com)

Chemical1

• The chemical name of spermidine is N-(3-aminopropyl) butane-1,4-diamine while the CAS number of spermine is 71-44-3 (free base) and 306-67-2 (tetrahydrochloride). (cimasci.com)

Biogenic2

• The objective of the present study was to evaluate the levels of biogenic amines (cadaverine, putrescine, tyramine, histamine, spermidine and spermine) by high performance liquid chromatography (HPLC) and the physicochemical (moisture, lipids, proteins, pH, water activity and fixed mineral residue) and microbiological (lactic acid bacteria and aerobic heterotrophic mesophilic bacteria count) characteristics of six Italian-type salami brands sold in the city of Niteroi (Rio de Janeiro, Brazil). (edu.pe)
• An ultra-high performance liquid chromatography-tandem mass spectrometry method for the determination of eight biogenic amines in Huangjiu (rice wine), including histamine, tyramine, putrescine, tryptamine, β-phenylethylamine, cadaverine, spermine and spermidine, was established. (spkx.net.cn)

Activity1

• It may also elevate spermidine/spermine acetyltransferase (SSAT) activity. (ewha.ac.kr)
