SpletThe average-weight human body contains about 100-110 mg of copper, highest content is located in liver cells, central nervous system, kidneys and heart. The essentiality of Cu is the consequence of its role in metalloenzymes involving several critical biochemical pathways. Splet25. okt. 2024 · The regulation of size, volume and mass in living cells is physiologically important, and dysregulation of these parameters gives rise to many diseases. Cell mass is largely determined by the amount of water, proteins, lipids, carbohydrates and nucleic acids present in a cell, and is tightly linked to metabolism, proliferation and gene expression.
