Unformatted sample text from the term paper:
Proteins are not only one of the lifes most important components, they are also one of the most diverse of its components. That diversity
is attributable to the fact that proteins are formed either solely from amino acids or from a combination of amino acids, organics, and/or inorganic compounds. The specific structure and
arrangement of those components determine protein characteristics and even the class to which a particular protein belongs. Proteins comprised solely of
amino acids, as might be expected, are classified as simple proteins. Those comprised of amino acids in conjunction with other organic or inorganic compounds such as carbohydrates, lipids, and
nucleic acids are classified as conjugated proteins. Conjugated proteins include glycoproteins (proteins containing carbohydrates), lipoproteins (proteins containing lipids), and nucleoproteins (proteins containing nucleic acids).
While each of the above components determines protein structure and function, the amino acid component of a protein is perhaps the most decisive factor in this regard.
Amino acids form all of lifes vital proteins, hormones, and enzymes (Colby). Amino acids are formed in the liver from the proteins obtained by the body through its food
sources. Amino acids sometimes function in the transport of molecules across cellular membranes by acting as a sort of shipping tag which identifies the molecule and allows it to
pass unheeded (Pennisi). Importin, a protein, is an example of this particular function (Pennisi). Importin joins the molecular binding process at a critical stage and serves to make
the cell recognize the substance and to allow it to pass the membrane unheeded (Pennisi). Interestingly, nearly all of amino acids
