Proteins are nothing but biological molecules that are very large in size and they consist of one or more than one chains of certain acids known as amino acids. These are mainly concerned about performing a series of certain functions that might be helpful to living organisms. Catalyzing metabolic reactions is an important task of proteins and they even help to replicate DNA and help to respond to stimuli. Molecules can be easily transported from one place to another by the help of these proteins. The amino acid sequence marks difference of one protein from another. Usually non peptide groups attached to proteins which are better known as cofactors or prosthetic groups.
A particular function can be easily achieved by proteins because they have the tendency to work together. Protein complexes are often formed when proteins associate to work together as a stable component. Proteins are really very essential parts all organisms and they virtually participate in all the processes within cells. Many of them are nothing but enzymes that help to catalyze some biochemical reactions that are very important for proper metabolism. They also have mechanical or structural functions mainly myosin present in muscle and actin and also proteins present in the cytoskeleton. This helps to maintain the shape of the cell.
Immune responses, cell signaling, cell adhesion and of curse cell cycle are some other factors which are being taken care of by proteins. These are also very important for animal diets. Ingested protein gets broken down into amino acids that are free and they are further used in metabolism. Usually proteins are comprised of polymers. These are generally assembled from the amino acids by the help of information that are encoded in the genes. Peptide synthesis is the process by which short protein synthesis is carried out. Usually proteins can be folded in 3 dimensional structures that are very unique.

It is rightfully said that a doctor is kept away by eating an apple every day. This proverb was introduced by J T Stinson, a fruit specialist in a world fair lecture in 1904. A large number of health benefits of apples have proven by research. First of all, chewing an apple helps to increase saliva production in the mouth which thereby kills bacteria and reduces the rate of tooth decay.
It helps to reduce the risk of lung cancer, colon cancer and also prostate cancer. Ursolic acid is contained within apple seeds which helps to increase brown fat and improves skeletal muscle. On the other hand it also decreases white fat, intolerance of glucose, cures obesity problems and diseases of fatty liver.
Peels of apple are an excellent source of various phytochemicals, the nutrition benefits of which are yet to be discovered. The known phytochemicals present in apple are epicatechin, quercetin, and procyanidin B2.
The department of agriculture in the United States has stated that a normal apple weighs 242 grams and it can provide 126 calories along with a significant amount of vitamin C and beneficial dietary fibers. The fiber binds with the intestinal fat which in turn reduces cholesterol level in the body.
In experiments conducted on mice, it has been proven that apple juice helps in increasing the production of neurotransmitter acetylcholine. Experiments have also been conducted on fruit flies which shows that flies feeding on apple has 10% longer life than flies living on normal food.
Recent studies show that apple juice reduces the risk of Alzheimers and decreases brain aging. It also provides a protection against Parkinsons disease. Besides there are also various other benefits like preventing cataracts, keeping a healthy heart etc. in short, it can be said that people who maintain a healthy diet rich in fruits, especially apple, successfully leads a healthy life.
