Whakamahinga
He matū maha ngā whakamahinga o te DL - Waikawa Tātarika, ā, he maha ngā whakamahinga. He whānuitia te whakamahinga i roto i te umanga kai me te inu hei waikawa, hei whakarei ake i te reka, hei whakahaere hoki i te pH. Ka taea e ia te whakaputa i te reka kawa me te whakapai ake i te reka o ngā hua pēnei i ngā inu ngohengohe, ngā wai hua, me ngā monamona. I roto i te umanga rongoā, ka whakamahia i roto i te hanganga rongoā me te hei kaiwhakarewa chiral. Hei tāpiri, ka kitea te whakamahinga o te DL - Waikawa Tātarika i roto i te umanga matū mō te hanganga o ngā esters me ētahi atu matū waro. Ka whakamahia hoki i roto i ētahi hua whakapaipai me te tiaki whaiaro hei whakatikatika i te pH me te whakarei ake i te pumau o ngā hanganga.
