Omega-6 fatty acids

DB13168

small molecule nutraceutical

Deskripsi

Omega-6 fatty acids are polyunsaturated fatty acids with a final carbon-carbon double bond in the n-6 position, that is, the sixth bond, counting from the methyl end. They are a family of fatty acid molecules that act as precursors to potent lipid mediator signalling molecules with either pro-inflammatory and anti-inflammatory effects. Cells involved in the inflammatory response are typically rich in the n-6 fatty acid arachidonic acid, as generally, eicosanoids derived from n-6 PUFA are pro-inflammatory. Arachidonic acid, which is a main precursor of eicosanoids, is an example of omega-6 (n-6) polyunsaturated fatty acids. Vegetable oil is a major dietary sources of omega-6 fatty acids.

1. Pendahuluan & Konsep

Fitur visualisasi ini dikembangkan menggunakan pendekatan Graph Theory untuk memetakan hubungan polifarmasi dan molekuler. Entitas (Obat, Target, Gen) direpresentasikan sebagai Simpul (Nodes), sedangkan hubungan biologisnya sebagai Sisi (Edges).

2. Sumber Data (Validasi)

Data Obat: Diekstraksi dari elemen drugbank-id dan name pada skema XML DrugBank.
Target Protein: Diambil dari elemen targets/target yang memuat polipeptida sasaran.
Genetik: Disinkronisasi dari sub-elemen gene-name dan varian snp-effects.
Genetik: Jumlah titik node dibatasi pada maksimal 10 (Slice=10) interaksi untuk menghindari tumpukan data.

3. Algoritma Visualisasi

Tata letak grafik menggunakan algoritma Force-Directed Graph (Barnes-Hut). Model fisika ini menerapkan gaya tolak-menolak antar simpul (Gravitasi: -3000) agar tidak tumpang tindih, serta gaya pegas (Spring: 0.04) pada garis penghubung untuk fleksibilitas interaksi.

Metabolisme

Most metabolism of polyunsaturated fatty acids occur in the liver but may occur in other tissues as well. Metabolism of omega-6 fatty acids leads to biosynthesis of eicosanoids, as mentioned above. Linoleic acid can be metabolized to other more unsaturated, long-chain members of the n-6 family by the insertion of additional double bonds during consecutive elongation and desaturation mechanisms. The initial rate limiting desaturation of LA to GLA is catalysed by the enzyme delta-6-desaturase (FADS2). Elongation then takes place to convert GLA to DGLA, by elongation of very long-chain fatty acids (ELOVL) 5, and finally a cycle of elongation and desaturation by delta-5-desaturase (FADS1) generates AA ^A19374.
