APAKAH MAKSUD ASCORBIC ACID dalam CORSICA?
Asid askorbik
Asid askorbik adalah sebatian organik yang semulajadi dengan sifat antioksidan. Ia adalah pepejal putih, tetapi sampel yang tidak suci boleh kelihatan kekuningan. Ia larut dalam air untuk memberikan penyelesaian yang berasid sedikit. Asid askorbik adalah satu bentuk vitamin C. Ia pada mulanya dipanggil asid L-heksuronik, tetapi, apabila didapati mempunyai aktiviti vitamin C pada haiwan, cadangan itu dibuat untuk menamakan semula asid L-heksuronik. Nama baru untuk asid L-heksuronik berasal dari a- dan scorbutus, penyakit yang disebabkan oleh kekurangan vitamin C. Kerana ia berasal dari glukosa, banyak haiwan mampu menghasilkannya, tetapi manusia memerlukannya sebagai sebahagian daripada nutrisi mereka . Haiwan vertebrata lain yang tidak mempunyai kemampuan untuk menghasilkan asid askorbik termasuk primata lain, babi guinea, ikan teleost, kelawar, dan beberapa burung, yang semuanya memerlukannya sebagai mikronutrien pemakanan. Terdapat asid D-askorbik, yang tidak berlaku secara semula jadi. Ia boleh disintesis secara buatan. Ia mempunyai ciri-ciri antioksidan yang serupa dengan asid L-askorbik namun mempunyai aktiviti vitamin C kurang. Fakta ini diambil sebagai bukti bahawa sifat antioksidan asid askorbik hanya sebahagian kecil daripada aktiviti vitamin yang berkesan.
