Inorganic materials – substances present in ash when food or any living organism cremated Oxygen, hydrogen, carbon and nitrogen excluded - these form organic compounds and not found in ash Building - Form part of skeleton and all soft tissues Hence, found in rigid body structures (bones) and soft body tissues (muscles) Regulatory function - associated with variety of systems: Heart beat Clotting of blood Maintenance of internal pressure of body fluids Nerve responses Transport of oxygen from lungs to tissues.
The mTOR protein is a 289-kDa serine threonine kinase that belongs to the phosphoinositide 3-kinase (PI3K)-related kinase family and is conserved throughout evolution. mTOR nucleates at least two distinct multi-protein complexes, mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2.
