Soft tissue - tissues that connect, support, or surround other structures and organs of the body.
Soft tissue includes muscles, tendons, ligaments, fascia, nerves, fibrous tissues, fat, blood vessels, and
synovial membranes.
Regulation - Living things have evolved to control the rate at which certain chemical reactions take
place. This regulation prevents organisms from wasting energy and helps them maintain their internal
environment
Anabolism - Complex biological molecules are often constructed from simpler precursors.
Reactions that build up molecules in this way are called "anabolic," and often require the input of
energy.
Thermodynamics - the chemical transformations that make life possible are governed by
thermodynamics. This literally means the "movement of heat," and refers to the behavior of energy in
physical systems.
Catabolism - Many complex biological molecules can be broken down into simpler molecules.
Reactions that break down molecules are called "catabolic," and often release energy that can be
harnessed by cells.
Structure - The functions of biological molecules are completely dependent on their chemical
structure. This includes both the physical shape of molecules as well as their chemical properties such as
charge and polarity.
