What is spermine used for?

What is spermine used for?

Spermine is an endogenous polyamine bearing multiple amino groups. It has been found to play important roles in cellular metabolism in all eukaryotic cells. It also can condense DNA in sperm due to its positive charge in the physiological condition.

What does spermine mean?

: a deliquescent crystalline aliphatic tetramine C10H26N4 found in semen in combination with phosphoric acid, in blood serum and body tissues, and in yeast.

Who invented spermine test?

1.2. Biogenic polyamines are an important class of natural occurring compounds, which were discovered by Antoni van Leeuwenhoek in 1678. These polyamines are present in tissues and cells of living organisms and play an important role in biological and pathological processes.

Is spermidine found in sperm?

1 Abundant amounts of sperm- ine (and much smaller quantities of spermidine) are found in human semen, presumably the result of prostatic secre- tion.

Does swallowing sperm make you live longer?

1 Department of Cellular and Molecular Physiology, The Pennsylvania State University College of Medicine, Hershey, PA.

What is the mechanism of action of spermine?

8.2 Mechanism of Action. Spermine functions directly as a free radical scavenger, and forms a variety of adducts that prevent oxidative damage to DNA. Oxidative damage to DNA by reactive oxygen species is a continual problem that cells must guard against to survive. Hence, spermine is a major natural intracellular compound capable…

What is the role of hypusine and spermidine?

Although spermidine has an essential and unique role as the precursor of hypusine a post-translational modification of the elongation factor eIF5A, which is necessary for this protein to function in protein synthesis, no unique role for spermine has been identified unequivocally.

What is the name of the derivative of spermine?

A derivative of spermine, N 1 , N 12 -bis (ethyl)spermine (also known as BESm) was investigated in the late 1980s along with similar polyamine analogues for its potential as a cancer therapy. Spermine biosynthesis in animals starts with decarboxylation of ornithine by the enzyme Ornithine decarboxylase in the presence of PLP.
