¿Qué es Phosphatidylserine (PS) 20-70%? Aplicaciones, dosis, alternativas y especificaciones

Phosphatidylserine, abbreviated as PS, also known as serine phospholipid or complex neuro acid, es un naturally occurring phospholipid ubiquitously present in cell membranes. It belongs to the phosphoglyceride class and es una important component of cell membranes. Chemically named 1,2-diacyl-sn-glycero-3-phospho-L-serine, PS consists of a serine residue and a phosphate residue attached to a glycerol backbone forming the hydrophilic head, and two long-chain hydrocarbon fatty acids forming the lipophilic tail, giving the molecule an amphiphilic nature. PS is the only phospholipid on the cell membrane con una net negative charge, contributing to membrane asymmetry, and it can activate the metabolism and synthesis of various enzimas, closely related to membrane fluidity, permeability, and multiple membrane functions. PS was first extractoed and characterized from bovine brain by Jordi Folch in 1942. Natural PS is mostly extractoed from bovine (ovine) brain or soybeans. Due to variations in the R1 and R2 fatty acid residues, PS es unctually a collective term for a class of compounds. El producto appears as a white to pale yellow loose polvo that can emulsify in water. PS can be synthesized by the human body using serine, and can also be obtained through dietary intake. It influences the transmission of chemical information in the brain and helps brain cells store and retrieve information, serving as an important nutrient for mantienening normal memory, reaction time, and healthy mood. El principal forms of PS are soy-derived PS and sunflower-derived PS. In recent years, sunflower-derived phosphatidylserine has emerged as a new choice debido a its low allergenicity and alta pureza, making it especially suitable for vegetarianos and those con unallergies. Additionally, genetic engineering technologies (como Pichia pastoris modification) have permitend microbiano synthesis of PS, achieving yields of 18 g/L and reducing costs by 40%. Phosphatidylserine products are disponible in various forms, incluyendo polvo (20%, 50%, 70%, 90%+ content), softgels, tablets, pressed candies, oral líquidos, and water-dispersible polvo (PS-CWD).

El núcleo active component of PS is phosphatidylserine itself. Its mechanisms of action include the following aspects:

PS es una important component of neural cell membranes, particularly abundant in brain cell membranes, earning it the nickname “brain vitamin”. It influences cell membrane fluidity and permeability, promoting the structural integrity and functional stability of neural cell membranes.
