31. IolB is involved in myo-inositol catabolism . 32. In protein catabolism , proteins are broken down by proteases into their constituent amino acids. 33. In fat catabolism , triglycerides are hydrolyzed to break them into fatty acids and glycerol. 34. There are many signals that control catabolism . 35. Galactokinase catalyzes the first committed step of galactose catabolism , forming galactose 1-phosphate. 36. The breakdown of large molecules into smaller molecules associated with release of energy is catabolism . 37. It is involved in the catabolism of heparin, heparan sulphate, and keratan sulphate. 38. GALC is responsible for the lysosomal catabolism of certain galactolipids, including galactosylceramide and psychosine. 39. The catabolism of the methyl compounds is mediated by methyl transferases to give methyl coenzyme M. 40. KYNU is part of the pathway for the catabolism of cofactors from tryptophan ( Trp ).
