Enzyme proteins frequently combine to form multimeric complexes that allow individual subunits to coordinate their activities and so perform more difficult tasks than they could alone. An example of such a complex is the ring ATPases in which several subunits form circular complexes consisting of identical (homomeric) or non-identical (heteromeric) subunits. These enzyme complexes use…

Read moreLittle is known about the effect of alcohol when drunk by individuals with type 1 diabetes. A study by Kerr et al looked at this in 7 males, 3 females with type 1 diabetes of long standing. They ate a standard 600 calorie lunch with 8 units of alcohol for men and 6 for women…
Read moreSherreffs has written an important review of the influence of exercise on water and electrolyte loss during sport. Sweat evaporation can be a key thermoregulatory mechanism and it causes a loss of water from all compartments of the body. Hypohydration can also develop with restricted fluid intake or with intake of diuretics. Hypohydration can affect…
Read moreBerks has written a fascinating review of trace elements and their binding to proteins. It has been estimated that a third of all proteins require the help of metal ions to carry out their biological functions’. In most cases, these proteins obtain their metal cofactors directly from their surroundings, and so they need a mechanism…
