Phospholipid
lipids containing phosphoric acid as a mono- or di-ester
Phospholipids are a class of lipids whose molecule has a hydrophilic "head" containing a phosphate group and two hydrophobic "tails" derived from fatty acids, joined by an alcohol residue (usually a glycerol molecule). Marine phospholipids typically have omega-3 fatty acids EPA and DHA integrated as part of the phospholipid molecule. The phosphate group can be modified with simple organic molecules such as choline, ethanolamine or serine.
Phospholipids are essential components of neuronal membranes and play a critical role in maintaining brain structure and function. They are involved in the formation of the blood–brain barrier and support neurotransmitter activity, including the synthesis of acetylcholine.
Research indicates that phospholipid levels in the brain decline with age, with studies showing up to a 20% reduction by age 80, potentially impacting memory, focus, and cognitive performance. Dietary supplementation with phospholipids derived from the milk fat globule membrane (MFGM) has been shown in clinical trials to support memory, mood, and stress resilience in both children and adults.
Multiple randomized controlled trials have demonstrated that daily intake of 300–600 mg of MFGM phospholipids can significantly reduce perceived stress and improve cognitive performance under pressure.
Phospholipids are a key component of all cell membranes. They can form lipid bilayers because of their amphiphilic characteristic.
Begin with the source’s own compact description: “Phospholipid” is lipids containing phosphoric acid as a mono- or di-ester. The dossier treats that line as a proposition to test through Phospholipid, lipids and containing, not as a finished interpretation.
Why this record matters
The phrase “lipids containing phosphoric acid as a mono- or di-ester” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q186915. The Library of Congress control number is sh85101108. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
