1,2-Distearoyl-sn-glycero-3-PC is a phospholipid containing the saturated long-chain (18:0) stearic acid inserted at the sn-1 and sn-2 positions. It is commonly used in the generation of micelles, liposomes, and other types of artificial membranes.

Is Distearoyl safe?

In the inhalation field, lipids such as egg phosphatidylcholine (PC), 1,2-distearoyl-sn-glycero-3-phosphocholine (DSPC) and dipalmitoylphosphatidylcholine (DPPC), are considered to be generally recognized as safe (GRAS), comprising materials that are endogenous to the lungs and locally present in large quantities.

What is D 1/2 Distearoyl Glycero 3 Phosphocholine?

1,2-distearoyl-sn-glycero-3-phosphocholine is a phosphatidylcholine 36:0 in which both phosphatidyl acyl groups are specified as stearoyl (octadecanoyl). It derives from an octadecanoic acid.

Where does Distearoyl SN Glycero 3 Phosphocholine come from?

1,2-Distearoyl-sn-glycero-3-phosphocholine (DSPC) is a phosphatidylcholine with stearoyl (octadecanoyl) acyl groups. It derives from an octadecanoic acid. Phosphatidylcholine (PC) is generally the most abundant lipid in animal cell membranes providing structural framework.

Is DSPC dangerous?

Given the use of air and vehicle controls in a range of inhalation toxicology studies as well as negative genotoxicity and also reproductive toxicity results, it is thought that the use of DSPC is shown to be safe for pulmonary administration.

What is Phosphocholine used for?

Because the body uses phosphatidylcholine to make a brain chemical called acetylcholine, there is some interest in using it for treating “brain-centered” conditions such as memory loss, Alzheimer's disease, anxiety, manic-depressive disorders, and a movement disorder called tardive dyskinesia.

What is DSPC found in?

Distearoylphosphatidylcholine (DSPC) is a phosphatidylcholine, a kind of phospholipid. It is a natural constituent of cell membranes, eg. soybean phosphatidylcholines are mostly different 18-carbon phosphatidylcholines (including minority of saturated DSPC), and their hydrogenation results in 85% DSPC.

Is phosphatidylcholine good for the liver?

Early research suggests that taking phosphatidylcholine by mouth, together with interferon, seems to improve liver function in people with hepatitis C. High levels of lipoproteins in the blood (hyperlipoproteinemia).

Is Phosphocholine a protein?

Phosphatidylcholine transfer protein (PC-TP) is a highly specific soluble lipid binding protein that transfers phosphatidylcholine between membranes in vitro. PC-TP is a member of the steroidogenic acute regulatory protein–related transfer (START) domain superfamily.

Why do liposomes form?

They typically form after supplying enough energy to a dispersion of (phospho)lipids in a polar solvent, such as water, to break down multilamellar aggregates into oligo- or unilamellar bilayer vesicles. Liposomes can hence be created by sonicating a dispersion of amphipatic lipids, such as phospholipids, in water.

What are side effects of 1/2 Distearoyl SN Glycero 3 Phosphocholine?

May cause respiratory tract irritation. Skin May be harmful if absorbed through skin. May cause skin irritation. Eyes May cause eye irritation.

What is the function of Phosphatidylethanolamine?

Phosphatidylethanolamine plays a role in the assembly of lactose permease and other membrane proteins. It acts as a 'chaperone' to help the membrane proteins correctly fold their tertiary structures so that they can function properly.

What is phosphocholine made from?

Phosphocholine is made in a reaction, catalyzed by choline kinase, that converts ATP and choline into phosphocholine and ADP. Phosphocholine is a molecule found, for example, in lecithin. ... Phosphocholine is a natural constituent of hens' eggs (and many other eggs) often used in biomimetic membrane studies.

Is phosphocholine a lipid?

Phosphatidylcholines (PC) are a class of phospholipids that incorporate choline as a headgroup. They are a major component of biological membranes and can be easily obtained from a variety of readily available sources, such as egg yolk or soybeans, from which they are mechanically or chemically extracted using hexane.

Does phosphatidylcholine help with weight loss?

Increases the Rate of Fat Breakdown

Phosphatidylcholine increases the production of this element within the human body, thus providing a boost to the rate of fat breakdown. Thus, it can be said that phosphatidylcholine supplements can safely be used for fat reduction and weight loss intervention.

What is the best vitamin for fatty liver?

Some studies show that vitamin E can also help treat NAFLD. The dose of vitamin E used in these studies is almost 40 times the recommended amount of vitamin E intake from food.

What is DSPC in vaccines?

The compositions of the lipid nanoparticles are very similar for the two vaccines (Pfizer/BioNTech and Moderna): an ionizable cationic lipid, a PEGylated lipid, cholesterol, and the phospholipid distearoylphosphatidylcholine (DSPC) as a helper lipid.

Can you take choline on an empty stomach?

Choline can be given with or without food; however, if stomach upset occurs when dosed on an empty stomach, give future doses with food. The powder is typically mixed with food.

Can choline reverse fatty liver?

Choline deficiency as a cause of hepatic steatosis is exemplified in the setting of total parenteral nutrition, in which choline replacement led to a reversal of fatty infiltration (23). Furthermore, dietary choline deficiency is routinely used in animal models of NAFLD (24).
