Iron

A side note about haemochromatosis:

Haemochromatosis is a disease where there is too much iron is in the body.  It is the most common form of iron overload disease. There are two types of haemochromatosis: 

<span>Primary haemochromatosis is a genetic disorder inherited from family members.  People with this condition absorb too much iron and it ends up accumulating in the body, especially in the liver.   </span><span>Secondary haemochromatosis is caused by other blood-related disorders such as anaemia, or may be due to many blood transfusions, long term alcoholism and/or other health conditions.    </span><span>If left untreated, iron overload can lead to liver damage. That’s why it’s important to receive treatment as soon as possible after diagnosis to prevent further complications, including liver disease, liver cirrhosis, liver failure, liver cancer, heart disease, arthritis or diabetes. Some organ damage can be reversed if detected early enough and treated appropriately.

cigarettes

If you smoke cigarettes there’s a chance that you are causing damage to your liver – increasing your risk of developing liver cancer and decreasing your liver’s ability to rid your body of dangerous toxins. In turn, this could leave you more susceptible to the damaging effects of some medications on the liver too. </span>

Name two structural and two functional properties of proteins
Inga [223]
1.Proteins are linear polymers built of monomer units called amino acids. The construction of a vast array of macromolecules from a limited number of monomer building blocks is a recurring theme in biochemistry. Does protein function depend on the linear sequence of amino acids? The function of a protein is directly dependent on its threedimensional structure.<span>Remarkably, proteins spontaneously fold up into three-dimensional structures that are determined by the sequence of amino acids in the protein polymer. Thus, </span>proteins are the embodiment of the transition from the one-dimensional world of sequences to the three-dimensional world of molecules capable of diverse activities<span>.

</span>2.Proteins contain a wide range of functional groups<span>. These functional groups include alcohols, thiols, thioethers, carboxylic acids, carboxamides, and a variety of basic groups. When combined in various sequences, this array of functional groups accounts for the broad spectrum of protein function. For instance, the chemical reactivity associated with these groups is essential to the function of </span>enzymes,<span> the proteins that catalyze specific chemical reactions in biological systems</span><span>
