Phosphatidylserine(Cas 51446-62-9) Usage

Biosynthesis

In mammalian cells, PS is endogenously synthesized via two pathways, both of which exchange the head group of phosphatidylcholine (PC) and phosphatidylethanolamine (PE) for serine, generating PS in both instances (Vance, 2008). PS synthase-1 (PSS1) catalyzes the choline exchange reaction and PS synthase-2 (PSS2) catalyzes the ethanolamine exchange reaction.PS Synthase 1: Phosphatidylcholine + L-Serine--->Phosphatidylserine + CholinePS Synthase 2: Phosphatidylethanolamine + L-Serine--->Phosphatidylserine + EthanolaminePS, both from endogenous synthesis and exogenous supplementation can be hydrolyzed via two pathways. This occurs via phospholipases, which are located in the plasmalemma (Leventis & Grinstein, 2010). The sn-1acyl chain of PS is hydrolyzed via the action of PSspecific phospholipase A1, while the sn-2 acyl chain of PS is hydrolyzed via PS-specific phospholipase A2, with lysophosphatidylserine (LPS) being formed in both cases. Lysophosphatidylserine produced through the hydrolysis of the sn-2 acyl chain has been implicated in a number of biological processes including mast cell activation and neural differentiation (Hossono, Aoki, Nagai, Bandoh and Ishida (2001); Aoki, Nagai, Hosono, Inoue, and Arai (2002).stars.library.ucf.edu

Biological Functions

Phosphatidylserine (PS) is a glycerophospholipid consisting of a phosphatidyl group attached to L-serine via a phosphodiester linkage. PS is a critical component of the cellular plasma membrane and accounts for 2-15% of plasma membrane lipid composition, depending on the cell or tissue type. The highest concentrations of PS are found in neuronal tissues, which are critical for maintaining conduction velocity in myelinated neurons, as well as for higher order cognitive skills such as learning and memory. In normal, healthy cells, PS is held in the inner membrane surface (facing the cytosol) by the lipid transporter protein flippase. However, in apoptotic cells, PS molecules ‘shuffle’ between the inner and outer plasma membrane monolayers. When PS molecules flip to the extracellular (outer) surface of the cell membrane, they act as a signal for macrophages to engulf and digest the (apoptotic) cell.

Side effects

When taken by mouth: Phosphatidylcholine is POSSIBLY SAFE when taken by mouth, in a dose up to 30 grams per day for 6 weeks, or up to 6 grams per day for 2 years. When phosphatidylcholine is taken by mouth, it can sometimes cause excessive sweating, stomach upset, and diarrhea.When given as a shot: Phosphatidylcholine is POSSIBLY SAFE when given as an injection under the skin for up to 5 doses spread 2-4 weeks apart. The injections can cause irritation, swelling, redness, itching, burning, bruising, and pain at the injection site. These side effects usually go away over a period of several days. Sometimes, phosphatidylcholine might cause gastrointestinal upset, like bloating, diarrhea, and nausea.If phosphatidylcholine is injected directly into a non-cancerous fatty tumor (lipoma), it might cause a reaction that could make the tumor more fibrous, needing surgery to remove it.When applied to the skin: Phosphatidylcholine is POSSIBLY SAFE when applied to the skin for up to 12 weeks.www.webmd.com

Safety

Small clinical trials suggest that phosphatidylserine supplements produce no serious adverse effects for elderly patients, although it may reduce blood pressure or increase body weight. Since some supplements are prepared from cow brains, it is theoretically possible for those supplements to transmit prion diseases such as mad cow, though no cases have been reported.
