CH2OH – (CHOH)2 - СН2 – C(O)H + 2 Cu(OH)2 = CH2OH – (CHOH)2 - СН2 – COOH + Cu2O + 2H2O
СH2OH – (CHOH)2 - СН2 – C(O)H + Н2 = СH2OH – (CHOH)2 - СН2 – CН2OH
CH2OH – (CHOH)2 - СН2 – C(O)H + 2 Cu(OH)2 = CH2OH – (CHOH)2 - СН2 – COOH + Cu2O + 2H2O
СH2OH – (CHOH)2 - СН2 – C(O)H + Н2 = СH2OH – (CHOH)2 - СН2 – CН2OH
