Proteins seem to be the key word nowadays amongst the many health conscious people around the world.

But how many of you know exactly the role proteins play in all living organisms?
Its role in living organisms is the most intriguing with the human anatomy being the most complex of all. It is a system that is fed by the most amazing array of proteins; both simple and complex proteins beyond the amino acid base. The role of proteins in living organisms and subsequent genetics is among the most important as the structure of protein strains helps us to understand how their presence actually affects us which can only be appreciated by first understanding, the presence and need of proteins and why proteins are good for you.
Its basic composition comprise of elements like oxygen, hydrogen, nitrogen and carbon with some others having traces of phosphorus and sulphur as well. As polymers of amino acids, proteins are an important class of biological macromolecules and are known as polypeptides when consisting of a sequence of 20 different L-α-amino acids (referred as residues). To enable them to perform their biological function, proteins fold into one, or more, specific spatial conformations, driven by a number of noncovalent interactions such as hydrogen bonding, ionic interactions, Van der Waals forces and hydrophobic packing.
In order to understand the functions of proteins at the molecular level, it is often necessary to determine the three dimensional structure of proteins which can be determined by X-ray crystallography or NMR spectroscopy.
Proteins can be of four distinct structures namely primary, secondary, tertiary and quaternary. For any biological function to take place, a number of residues are necessary with 40-50 residues being the lower limit. Protein sizes range from this lower limit to several thousand residues in multi-functional or structural proteins. However, the current estimate for the average protein length is around 300 residues. Very large aggregates can be formed from protein subunits such as the ‘R’ group needed to form active enzyme and related bonds with different molecules.
Protein components vary very different that when they are linked together, the result is a peptide bond which is responsible for each protein trace having unique properties and uses. The amino acids are linked via primary, secondary, tertiary or quaternary structures with each of theses unique links influencing the bonds of the protein strains.
Proteins play an important role in the lifespan, quality and health of human life, in particular. Depending upon the roles, the bonds and the structure of amino acid, the proteins in the cell membrane play the role of channels to facilitate diffusion. The resultant have polar side groups that improve their solubility in water. The non-polar folding enables the protein strains to keep water out and this avoids unfolding. It facilitates diffusion and act as transporters, binding with glucose molecules to transport them to the other side of the membrane; allowing the glucose to detach for cell adsorption and consumption. Proteins, in living organisms, play the role of channels to transfer molecules according to electrical and chemical qualities.
Proteins also function as organic catalysts in the human anatomy in catalyzing a number of important biochemical reactions. Proteins go beyond the body; they also affect the world at large in this capacity within the human body. Enzymes are particularly influenced by the proteins’s tertiary structure in its ability to use energy from a reaction to affect and help one involving them.
The human protein-based DNA have great tales to reveal. Immuno-proteins, being blood proteins can influence the human immune system. Soluble proteins that get linked to antigen can also affect the regulation of the immune system in affecting its hypersensitivity; resulting in an attack on microbes, which helps to ward off infection. Fibrinogen is another protein strain essential to protect the system when there is an injury with the blood platelets able to use the fibrinogen in the blood plasma to form fibrin in sealing off the wound; thus preventing the entry of any foreign infection possibility.
As hormones, proteins facilitate trigger reactions in the body and thus regulates homeostasis. One great example is that of insulin, a globular protein whose primary function is to regulate the quantity of soluble sugar in blood. Another protein wonder is Glucagon, the human growth hormone. Haemoglobin, the transport proteins, assist in carrying oxygen from the lungs to the tissues whilst myoglobin carries oxygen from the haemoglobin to the muscles as and when needed. The iron-transporting protein, transferrin is is essential in carrying iron within the immune system with casein being supplied to the human baby with the nutrition required to develop bones and encasing muscle.
During human procreation, proteins play the vital role of storage. The role of proteins in living organisms is most prominently seen as part of seed germination. It provides nitrogen to the developing embryo. Other living organisms, like plants, benefit from the presence of proteins manifesting within the storage organs, such as the case with the roots and shoots of tubers. Plant proteins are very essential to humans and other living things that consume them. They form an important part of human nutrition. The amino acids are very vital for the replacement of what the human anatomy is not capable of doing itself.
Proteins are just more than what has been mentioned herein before. They represent the many hidden treasures which scientists today are trying to unlock to discover their potential in many beneficial functions, their adverse functions role in enhancing and aiding diseases.
It can seen that in order to attain great healthy living, one must not ignore the basic building block of protein as it affects your everyday life. Your health depends how well it functions from the food that you intake, your genetic background, the environment and many other aspects. It is your choice to take an interest in them.
