Tegesé saka "lipid" ing bausastra Basa Inggris

Lipid minangka klompok molekul alami sing kalebu lemak, lilin, sterol, vitamin larut lemak, monoglycerides, diglycerides, trigliserida, fosfolipid, lan liya-liyane. Fungsi biologi utama lipid kalebu nyimpen energi, menehi tandha, lan minangka komponen struktural membran sel. Lipid duwe aplikasi ing industri kosmetik lan panganan uga nanoteknologi. Lipid bisa ditemtokake sacara luas minangka molekul cilik hidrofobik utawa amphiphil; sifat amphiphil saka sawetara lipid ngidini supaya mbentuk struktur kayata vesikel, liposom, utawa membran ing lingkungan banyu. Lipid biologis asalé saka utawa loro saka rong subunit biokimia utawa "bangunan-blok" sing béda: kelompok ketoacyl lan isoprena. Nggunakake pendekatan iki, lipid bisa dipérang dadi wolung kategori: asam lemak, gliserolipid, gliserofosfolipid, sphingolipid, saccharolipid, lan polyketida; lan sterol lipid lan prenol lipid. Senadyan lipid istilah iki kadhangkala dipigunakaké minangka sinonim kanggo lemak, lemak minangka subkelompok lipid sing disebut trigliserida. Lipids are a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides, phospholipids, and others. The main biological functions of lipids include storing energy, signaling, and acting as structural components of cell membranes. Lipids have applications in the cosmetic and food industries as well as in nanotechnology. Lipids may be broadly defined as hydrophobic or amphiphilic small molecules; the amphiphilic nature of some lipids allows them to form structures such as vesicles, liposomes, or membranes in an aqueous environment. Biological lipids originate entirely or in part from two distinct types of biochemical subunits or "building-blocks": ketoacyl and isoprene groups. Using this approach, lipids may be divided into eight categories: fatty acids, glycerolipids, glycerophospholipids, sphingolipids, saccharolipids, and polyketides; and sterol lipids and prenol lipids. Although the term lipid is sometimes used as a synonym for fats, fats are a subgroup of lipids called triglycerides.
