Mae carbohydrad yn gyfansoddyn organig sydd â'r fformiwla empirig Cm(H2O)n; hynny yw, yn cynnwys carbon, hydrogen ac ocsigen yn unig, gyda chymhareb atomau hydrogen:ocsigen o 2:1 (yr un peth a dŵr).
Gellir ystyried carbohydradau fel hydradau o garbon, sef sut cawsant eu henw. O ran strwythur fodd bynnag, mae'n rheitiach i'w hystyried fel polyhydroxy aldehydes a cetonau.
