The nourishment or feeding of cells, especially how cells obtain and use nutrients.
From cyto- (Greek kytos, 'cell') + -trophy (Greek -trophia, from trophē, 'nourishment'). A technical term developed in cellular biology to describe nutritional processes at the cellular level.
Different cells in your body have wildly different cytotrophy needs—your brain cells are gluttons for glucose while muscle cells during exercise preferentially burn fat. Understanding cytotrophy explains why certain diseases or toxins hit different organs hardest.
