Denaturation causes a protein to lose its biological function. For example, a denatured enzyme would no longer be able to catalyze a reaction. More »

Exposure to an extreme environment, such as high temperature, acidity or alkalinity, causes protein denaturation. Denaturation disrupts and destroys the secondary and tertiary structures of proteins, warping them from a ... More »

The end product of protein metabolism is typically nitrogenous waste in the form of ammonia, urea or uric acid. If it is not properly excreted from the body, these substances may build up in the body's systems and result... More »

Enzymes are primarily protein and act as biological catalysts in a wide variety of vital metabolic processes. Simple enzymes are comprised of protein only and conjugated enzymes are those which are comprised of both a pr... More »

Bone tissue is made up mostly of calcium and collagen, which is a protein. The outer layer of bone is hard and dense and called compact or cortical bone. The inner layer is called trabecular or cancellous bone. It is lig... More »

Enzymes are a type of protein, and like other proteins, they are made by the translation of the genetic code into a particular sequence of amino acids by ribosomes. After the enzyme is created as a chain of amino acids, ... More »
