polyamine

A diamine is a type of polyamine with exactly two amino groups.

While the principal idea of polyamine block is understood, the specific mechanisms are still controversial.

Norspermidine is a polyamine of similar structure to the more common spermidine.

This reaction is the committed step in polyamine synthesis.

At the mature stage, this species exhibits several adaptations linked to cold tolerance such as high polyamine levels.

Grapefruit contains large quantities of a simple polyamine called spermidine, which may be related to aging.

Another major role of SAM is in polyamine biosynthesis.

(2) Spermidine is a polycationic polyamine involved in cellular metabolism.

The polyamine spermine is produced, which triggers carpospore production.

His experiments showed that a substance called polyamine oxidase could kill parasites infecting red cells.

It uses the characteristics of aliphatic polyamine.

If cellular polyamine synthesis is inhibited, cell growth is stopped or severely retarded.

Spermine is a polyamine involved in cellular metabolism found in all eukaryotic cells.

According to recent studies, polyamine suppresses excessive immune reactions, and nattō has a much larger amount of it than any other food.

This enzyme regulates cell division by catalysing the first step in polyamine biosynthesis.

This polymer was first made early in 1935, and thanks to concurrent development of polyamine spinning technologies, could be spun into fibers.

Similar penta- and hexadentate ligands have been synthesized by varying the polyamine chain.

Ornithine decarboxylase is an enzyme integral in polyamine synthesis and vital for cell growth.

Droplet size, Dr. Sumper suggests, may depend on the polyamine combination, which is specific to each species.

The critical role of polyamines in cell growth has led to the development of a number of agents that interfere with polyamine metabolism.

The polyamine products of the pathway initialized by ODC are associated with increased cell growth and reduced apoptosis.

In this particular concept the sulfonyl groups can be removed by organic reduction with naphthalene (7), lithium metal and methanol to the free polyamine 8.

Most eukaryotic cells have a polyamine transporter system on their cell membrane that facilitates the internalization of exogenous polyamines.

EDTA and other polyamine polycarboxylic acids are used as iron ligands in colour bleach solutions.
