APAKAH MAKSUD LIGNAN dalam CORSICA?
Lignan
Lignans adalah sekumpulan sebatian kimia yang terdapat dalam tumbuhan. Lignans tumbuhan adalah bahan polifenol yang berasal dari fenilalanin melalui dimeralisasi alkohol sininik yang digantikan, yang dikenali sebagai monolignol, kepada skeleton dibenzylbutane. 2. Reaksi ini dikatalisis oleh enzim oksidatif dan sering dikawal oleh protein yang dirasakan. Banyak produk semulajadi, yang dikenali sebagai phenylpropanoids, dibina daripada unit C6C3 yang diperolehi daripada unit cinnamyl seperti kimia terpene yang dibina pada unit isoprena. Struktur 3 adalah neolignan, suatu struktur yang terbentuk dengan bergabung dengan dua sisa propylbenzene selain daripada atom karbon β dari rantai sisi propyl. Beberapa contoh lignans adalah pinoresinol, podophyllotoxin, dan steganacin. Apabila sebahagian daripada diet manusia, beberapa lignans dimetabolisme untuk membentuk lignans mamalia yang dikenali sebagai enterodiol dan enterolactone oleh bakteria usus. Lignans yang boleh dimetabolisme untuk membentuk lignans mamalia adalah pinoresinol, lariciresinol, secoisolariciresinol, matairesinol, hydroxymatairesinol, syringaresinol dan sesamin. Lignans adalah salah satu golongan utama phytoestrogens, yang merupakan bahan kimia seperti estrogen dan bertindak sebagai antioksidan.
