| The human cell contains endosymbiotic archaea with ability to catabolize cholesterol and synthesise digoxin. |
| During pro-longed recoveries, patients can catabolize up to one-tenth of their muscle mass despite putting on weight. |
| The bacterium's ability to catabolize biphenyls is directly related to the presence of a locus of approximately thirteen genes known as the bph cluster. |
| Two known enzymes catabolize the essential amino acid tryptophan in mammals. |
| Microorganisms which are able to produce L-carnitine from gamma-butyrobetaine or from a mixture of gamma-butyrobetaine and crotonobetaine and which do not catabolize L-carnitine. |
| Chronic, excessive intake of protein elevates the activity of enzymes that catabolize it or convert it to fat. |
