Increase or decrease in the concentration of certain proteins, or other substances, including micronutrients, in blood serum, following infections or tissue- inflammatory reactions. This reaction represents the body’s normal response in counteracting the deleterious effects of a noxious stimulus, but the changes in distributions of proteins and nutrients between body compartments can confound attempts to…

A variety of serum proteins synthesised in increased (or sometimes decreased) amounts in response to trauma and infection, so confounding their use as indices of nutritional status. Blood proteins produced in the liver that function in the innate immune response. APPs are important in the response to infection and inflammation. Any of the plasma proteins…

Energy-requiring transport of solutes across cell membranes, against the prevailing concentration gradient. Cell-mediated, energy-requiring translocation of a molecule across a membrane in the direction of increasing concentration (i.e., opposite of natural tendency). In physiology, an energy- producing process by which certain nutrients are pumped from one compartment to another against a concentration gradient. Active transport…

A chemical that can be generated when the amino acid asparagine is heated above 100°C in the presence of sugars. The amide of acrylic acid, C3H5NO. Acrylamide is used in many types of gel electrophoresis to separate and to identify proteins.  

Severe functional zinc deficiency due to failure to secrete an as yet unidentified compound in pancreatic juice that is required for zinc absorption.
