Covalent modification is the alteration of a synthesized protein facilitated by a catalyst. The structure and function of the protein is modified, changing its role in cellular regulation. 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 nucleus indirectly controls what happens in a lysosome by producing DNA that is copied into a protein, which then binds to the DNA that builds lysosomes. Lysosomes, small enzyme-filled sacs, are responsible for the d... More »

The basic building blocks of protein are amino acids, organic compounds that contain the chemical subunits known as an amino group and a carboxyl group. To form proteins, amino acids bond to one another with a special ch... 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 »

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 »

Some of the key functions of protein involve energy production, transportation, boosting the immune system and replenishing body tissue. Proteins are some of the most essential nutrients for human beings, and they can be... More »
