Proteins are large macromolecules which consist of hydrogen, carbon and oxygen; proteins are polymeric chains that are built from monomers known as amino acids. Proteins have a major function in a living organism, for example, the replication of DNA, catalysing metabolic reactions (catalyst); stimulus response and also transporting molecules form one place to another.

Proteins are the most abundant organic molecules present on earth. They are present abundantly in every living cell. Proteins are the polymers made up of thousands of amino acids linked via peptide bonds. Long chains of amino acids known as polypeptides fold around themselves in several ways to form complex structures called proteins.
Importance of protein It goes without saying that all life forms on this planet require protein in one form or the other; it is one of the basic building blocks of life, one which cells utilize to repair the damaged tissues and to grow new cells.

You could write an essay about each one, but thats alot of writing and as it probably won't be able to get it marked by an examiner then it may have limited use repeatedly writing out essays for each of these titles.Although if you have done one you could try posting it in the guestbook for others to read.
The proteins we gain through eating are processed into amino acids and use to replace the proteins already found in the body. There is a total of 20 different amino acids that combine together to make the different proteins. Amino acids that cannot be produce by the body are known as essential amino acids, and are acquired through the foods we eat.
Protein Structure Protein Structure. Proteins and large polymers made up of amino acids. These amino acids are arranged in a series of structures to create the finished 3D protein. There are up to four levels of structural arrangements in a protein, see the image below, which will each be explained fully.
Proteins such as RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) in the nuclei of our cells are responsible for the genetic code. Structural proteins. Proteins are also essential for the body structure. Bone consists of a protein matrix that fills with calcium and other minerals.
Crude protein analysis (quantification of protein). Protein sequence analysis is necessary to analyze the sequence of amino acids or peptides in proteins like Insulin. Insulin was previously used from animals like pigs, cattle for diabetes treatment.
Discovered in 1838, proteins are recognized as a large number of superior organic compounds that make up living organisms and are essential for their functioning. In other words proteins are the building blocks of life. They do many tasks for the human body and other organisms, that could not be done individually. These macromolecules could function as structural proteins and form structures.
Protein is crucial to good health. In fact, the name comes from the Greek word proteos, meaning “primary” or “first place.”. Proteins are made up of amino acids that join together to form.
Enzymes are proteins with a 3-D Tertiary construction which can change in form if certain factors such as temperature. pH or substrate concentration alteration. and so the active site of the enzyme may no longer congratulate the base of the substrate hence fewer composites can organize and the reaction rate beads.
