Putrescine aminopropyltransferase is responsible for biosynthesis of spermidine, spermine, and multiple uncommon polyamines
in osmotic stress-tolerant alfalfa.
Our new product HYDROSOFT C-60-W is a ternary block functional silicone copolymer, which combines several chemical entities in one linear molecule (siloxane, Polyamine
and polyether copolymer).
17, 2017), "Explosive-Detection Polymer Comprising Functionalized Polyamine
Polymers and Methods of Using the Same," Yu Lei and Ying Wang (University of Connecticut, Farmington, Conn.
are also found to improve fruit quality in mango (Malik and Singh, 2006), litchi (Mitra and Sanyal, 1990) and sweet orange (Saleem et al.
SSAT cellular toxicity is thought to be caused by produced acetylated polyamines
, which are utilized by APAO.
Zhao and colleagues found that when the cells were in an electric field, the positively-charged polyamines
tend to accumulate at the side of the cell near the negative electrode.
(putrescine, spermine and spermidine) have also been indicated to play an important part in cell proliferation and growth.
aureus and Enterobacteria, and increased fecal levels of polyamines
These secondary metabolite including phenolics brassinosteroids jasmonates salicylates polyamines
(PAs) are known as a group of natural compounds with aliphatic nitrogen structure that are ubiquitous in plants, animals and microorganisms.
3), (8) Polyamines
are critical for the effective regulation of normal cell growth, (3), (9) and evidence suggests they play a role in programmed cell death (apoptosis).
can be considered suitable starting materials for the preparation of liquid crystalline polyamines
by means of chemical modification, which can combine the existence of an ordered structure with the presence of basic and coordinative positions.
