陽光的UVB紫外線能轉化皮膚內的Provitamin D3為Vitamin D3 (維他命D),供我們身體所用。451Please respect copyright.PENANAg8Oc5p0Ujt451Please respect copyright.PENANAYWAKbDdEdr

蕃茄遇上UVB紫外光後,亦有機制將Provitamin D3轉為Vitamin D3 ,唯蕃茄當中亦有機制把Provitamin D3轉為其他物質,故最終的Vitamin D3含量並不為高。451Please respect copyright.PENANA2Owh22iQlS

近日有科學家利用基因編輯技術(Ref1),把7-DR2基因剔除,促使在UVB紫外線照射的情況下有更多的Provitamin D3能夠轉化成為Vitamin D3。若能將此蕃茄品種繼續加以改良及發展至市場,此蕃茄或許能成為人類吸取維他命D的主要來源之一。451Please respect copyright.PENANAwjponDwhIi
