Definition of Protein
Proteins are high molecular weight complex organic compounds which are polymers of amino acid monomers that are connected to each other by peptide bonds. Protein molecules contain carbon, hydrogen, oxygen, nitrogen and sometimes sulfur and phosphorus. Protein plays an important role in the structure and function of all living cells and viruses. Most of the protein is an enzyme or enzyme subunit. Other types of proteins play a role in structural or mechanical functions, such as proteins that make up the cytoskeleton in the stem and joints.
Protein is involved in the immune system (immune) as an antibody, a control system in the form of hormones, as a storage component (in seeds) and also in nutrient transportation. As one source of nutrition, protein acts as a source of amino acids for organisms that are unable to form these amino acids (heterotrophs). Protein is one of the giant biomolecules, in addition to polysaccharides, lipids and polynucleotides, which are the main constituents of living things. In addition, protein is one of the most studied molecules in biochemistry.
Protein was discovered by Jöns Jakob Berzelius in 1838. Biosynthesis of natural proteins equals genetic expression. The genetic code carried by DNA is transcribed into RNA, which acts as a template for the translation by the ribosome. Until this stage, the protein is still "raw", only composed of proteinogenic amino acids. Through the post-translational mechanism, proteins are formed which have full biological functions. Sources of protein come from Meat, Fish, Eggs, Milk, and similar products of Quarks, Plant seeds, Tribes of legumes and Potatoes.
Protein (protos which means "foremost") is a complex organic compound that has a high molecular weight which is a polymer of amino acid monomers that are connected to each other by peptide bonds. Peptides and proteins are amino acid condensation polymers by removing water elements from amino groups and carboxyl groups.
If the molecular weight of a compound is less than 6,000, it is usually classified as a polypeptide. Proetin is contained in many foods that are often consumed by humans. As in tempeh, tofu, fish and so on. In general, the source of protein is from vegetable and animal sources. Protein is very important for the life of organisms in general, because it serves to repair damaged body cells and supply the nutrients the body needs. So, it is important for us to know about protein and related matters. Protein is one of the giant biomolecules in addition to polysaccharides, lipids and polynucleotides which are the main constituents of living things.
Proteins are high molecular weight complex organic compounds which are polymers of amino acid monomers that are connected to each other by peptide bonds. The protein molecule itself contains carbon, hydrogen, oxygen, nitroge and sometimes sulfur and phosphorus. The protein was formulated by Jons Jakob Berzelius in 1938.
Components of Protein Components
The basic unit of protein structure is amino acids. Amino acids are organic compounds that contain amino groups (NH2), a carboxylic acid group (COOH), and one of the other groups, especially from a group of 20 compounds that have the basic formula NH2CHRCOOH, and are linked together by peptide bonds. In other words, proteins are composed of amino acids that bind to one another.
Amino acid structure An amino-α acid consists of:
Atom C α. Called α because it is next to a carboxyl (acid) group.
The H atom is bound to the C α atom.
Carboxyl groups are bound to the C α atom.
The amino group is bound to the C α atom.
The R group which is also bound to the C α atom.
Public health
Public Health is efforts to overcome sanitation problems that interfere with health. In other words, public health is the same as sanitation.
Efforts to improve and improve environmental sanitation are public health activities. Then at the end of the 18th century, found by bacteria that cause disease and several types of immunization, public health activities are the prevention of diseases that occur in the community through improved sanitation and prevention of diseases through immunization.
At the beginning of the 19th century, public health had progressed well, public health was defined as the application of integration between medical science, sanitation, and social science in preventing diseases that occurred in the community.
In the early 20th century, Winslow (1920), public health was a science and art: preventing disease, prolonging life, and improving health, through "Community Organizing Efforts" to:
Improvement of environmental sanitation
Eradication of infectious diseases
Education for personal hygiene
Organizing medical services and treatments for early diagnosis and treatment
Development of social engineering to ensure everyone is fulfilled the needs of a decent life in maintaining their health.
