Introduction:
Protein are the central to life because they control almost all cellular processes, including initiating most of the reactions that occur in the living thing cells. They are one of the building blocks of body tissue and also can serve as fuel source. They are naturally occurs which means that they are made by living cells, like animals, bug, fungi and even human. They can interact with one another and other biological macro mules to form complex assemblies. Some are quite rigid whereas others display limited flexibility. With modern technologies and advance knowledge, synthetic protein which is mimicking the function and structure of true protein can be made. Protein is a natural polymer. It is a polymer …show more content…
Haemoglobin, for example, carries oxygen to body tissues from the lungs. Serum albumin carries fats in your bloodstream, while myoglobin absorbs oxygen from haemoglobin and then releases it to the muscles. Calbindin is another transport protein that facilitates the absorption of calcium from the intestinal walls.
7.Receptor
Located on the outer part of the cells, receptor proteins control the substances that enter and leave the cells, including water and nutrients. Some receptors activate enzymes, while others stimulate endocrine glands to secrete epinephrine and insulin to regulate blood sugar levels.
8.Contractile
Also known as motor proteins, contractile proteins regulate the strength and speed of heart and muscle contractions. These proteins are actin and myosin. Contractile proteins can cause heart complications if they produce severe contractions.
Applications of protein: Protein had been applied in many researches over the years. Some of the applications are it is use as therapeutic to increase circulating lifetime, reduce immunogenicity and simplify the handling of pharmaceutical protein, also it is use as encapsulate for the protection and targeted delivery of sensitive ingredients in food industry and it is acts as artificial viral component by mimicking viral capsid
