The degradation of cholesterol by Pseudomonas sp. NCIB 10590 under aerobic conditions. 1. R W Owen‚ 2. A N Mason and 3. R F Bilton ABSTRACT The metabolic pathway of cholesterol degradation by bacteria has not been completely established. Several possible intermediates have not been identified and many pathway delineations have not involved the use of the cholesterol molecule per se and just one bacterial species. The bacterial degradation of cholesterol by Pseudomonas sp. NCIB

Biology Exam Review Unit One – Biochemistry What is an isotope? Isotope - An isotope is all atoms of the same element that have the same number of protons‚ but they may have different numbers of neutrons in the nucleus. - This means that all atoms with the same atomic number can have different atomic masses. - Because they have the same number of protons and electrons‚ they behave exactly the same in chemical reactions. Radioisotope - The nuclei of some isotopes of an element are unstable
