phospholipid
Biochemistry term for a lipid containing a phosphate group; a major component of cell membranes.
Cell membranes are mainly composed of a phospholipid bilayer.
Standard modern spelling using katakana for リン and kanji for 脂質.
Older kanji form using 燐 for the phosphorus component; now largely replaced by リン脂質.
Compound of リン (phosphorus) and 脂質 (lipid). The spelling 燐脂質 uses the older kanji 燐 for phosphorus.
