Txo cov suab thaj yog cov suab thaj uas cov pa roj carbon monoxide muaj OH pawg txuas uas tuaj yeem txo lwm cov tebchaw. Tsis yog- txo cov suab thaj tsis muaj OH pawg txuas nrog cov pa roj carbon monoxide kom lawv tsis tuaj yeem txo lwm cov tebchaw… M altose thiab lactose txo cov suab thaj, thaum sucrose yog cov piam thaj tsis txo qis.
Kev txo qis thiab tsis txo cov suab thaj piav qhia piv txwv li cas?
