Proteins are composed of amino acids and play many essential roles in the body. They have four levels of structure: primary, secondary, tertiary, and quaternary. The primary structure is the amino acid sequence, secondary involves hydrogen bonding into shapes like alpha helices and beta sheets, tertiary is the 3D folding of these structures, and quaternary involves the assembly of multiple protein subunits. Proteins serve as enzymes, hormones, antibodies, and structures. They undergo synthesis from amino acids and breakdown through catabolism. Disorders can occur if amino acid metabolism is disrupted.

Proteins are the macromolecules responsible for the biological processes in the cell. They consist at their most basic level of a chain of amino acids, determined by the sequence of nucleotides in a gene. Depending on the amino acid sequence (different amino acids have different biochemical properties) and interactions with their environment, proteins fold into a three-dimensional structure, which allows them to interact with other proteins and molecules and perform their function
INTRODUCTION TO METABOLISM OF PROTEIN AND AMINO ACIDS Rabia Khan Baber
Protein are the important tissue builders in body which it can help in the cell structure, functions, hemoglobin formation to carry oxygen, enzyme for metabolic reaction and other functions in the body. Also in supply the nitrogen for the DNA and RNA genetic materials and the energy production. This is because, protein contain long chain of amino acids
Protein metabolism is the process to breakdown foods are used by During protein metabolism, some of the protein will converted into glucose through gluconeogenesis process.
Protein is a macronutrient that is essential to building muscle mass. It is commonly found in animal products, though is also present in other sources, such as nuts and legumes. There are three macronutrients: protein, fats and carbohydrates. Macronutrients provide calories, or energy.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

3. History Proteins were first described by the Dutch chemist Gerardus Johannes Mulder and named by the Swedish chemist Jöns Jacob Berzelius in 1838. Early nutritional scientists such as the German Carl von Voit believed that protein was the most important nutrient for maintaining the structure of the body, because it was generally believed that "flesh makes flesh.“The central role of proteins as enzymes in living organisms was however not fully appreciated until 1926, when James B. Sumner showed that the enzyme urease was in fact a protein. The first protein to be sequenced was insulin, by Frederick Sanger, who won the Nobel Prize for this achievement in 1958. The first protein structures to be solved were hemoglobin and myoglobin, by Max Perutz and Sir John Cowdery Kendrew, respectively, in 1958. The three-dimensional structures of both proteins were first determined by X-ray diffraction analysis; Perutz and Kendrew shared the 1962 Nobel Prize in Chemistry for these discoveries.

5. Levels of Protein Structure Primary Structure The primary structure refers to amino acid sequence of the polypeptide chain. The primary structure is held together by covalent or peptide bonds, which are made during the process ofprotein biosynthesis or translation. The two ends of the polypeptide chain are referred to as the carboxyl terminus (C-terminus) and the amino terminus (N-terminus) based on the nature of the free group on each extremity. Counting of residues always starts at the N-terminal end (NH2-group), which is the end where the amino group is not involved in a peptide bond. Secondary Structure Secondary structure refers to highly regular local sub-structures. These secondary structures are defined by patterns of hydrogen bonds between the main-chain peptide groups. They have a regular geometry, being constrained to specific values of the dihedral angles ψ and φ on the Ramachandran plot. Both the alpha helix and the beta-sheet represent a way of saturating all the hydrogen bond donors and acceptors in the peptide backbone.
6. Levels of Protein Structure Tertiary Structure Tertiary structure refers to three-dimensional structure of a single protein molecule. The alpha-helices and beta-sheets are folded into a compact globule. The folding is driven by the non-specific hydrophobic interactions (the burial of hydrophobic residues from water), but the structure is stable only when the parts of a protein domain are locked into place by specific tertiary interactions, such as salt bridges, hydrogen bonds, and the tight packing of side chains and disulfide bonds. The disulfide bonds are extremely rare in cytosolic proteins, since the cytosol is generally a reducing environment. Quaternary Structure Quaternary structure is a larger assembly of several protein molecules or polypeptide chains, usually called subunits in this context. The quaternary structure is stabilized by the same non-covalent interactions and disulfide bonds as the tertiary structure. Complexes of two or more polypeptides (i.e. multiple subunits) are called multimers.
7. Functions of protein Antibodies Hormonal Proteins are specialized proteins involved in defending the body from antigens (foreign invaders). One way antibodies destroy antigens is by immobilizing them so that they can be destroyed by white blood cells. are messenger proteins which help to coordinate certain bodily activities. Examples include insulin, oxytocin, and somatotropin. Insulin regulates glucose metabolism by controlling the blood-sugar concentration. Oxytocin stimulates contractions in females during childbirth. Somatotropin is a growth hormone that stimulates protein production in muscle cells. Contractile Protein are responsible for movement. Examples include actin and myosin. These proteins are involved in muscle contraction and movement. Structural Proteins Enzymes are fibrous and stringy and provide support. Examples include keratin, collagen, and elastin. Keratins strengthen protective coverings such as hair, quills, feathers, horns, and beaks. Collagens and elastin provide support for connective tissues such as tendons and ligaments. are proteins that facilitate biochemical reactions. They are often referred to as catalysts because they speed up chemical reactions. Examples include the enzymes lactase and pepsin. Lactase breaks down the sugar lactose found in milk. Pepsin is a digestive enzyme that works in the stomach to break down proteins in food.
8. Functions of protein Storage Proteins store amino acids. Examples include ovalbumin and casein. Ovalbumin is found in egg whites and casein is a milk-based protein. Transport Proteins are carrier proteins which move molecules from one place to another around the body. Examples include hemoglobin and cytochromes. Hemoglobin transports oxygen through the blood. Cytochromes operate in the electron transport chain as electron carrier proteins.

11. The glucose-alanine cycle is the main pathway by which amino groups from muscle amino acids are transported to the liver for conversion to glucose. The liver is the main site of catabolism for all essential amino acids, except the branched-chain amino acids, which are catabolized mainly by muscle and the kidneys. Plasma amino-acid levels are affected by dietary carbohydrate through the action of insulin, which lowers plasma amino-acid levels (particularly the branched-chain amino acids) by promoting their entry into the muscle. Body proteins are broken down when dietary supply of energy is inadequate during illness or prolonged starvation. The proteins in the liver are utilized in preference to those of other tissues such as the brain. The gluconeogenesis pathway is present only in liver cells and in certain kidney cells. Disorders of amino acid metabolism include phenylketonuria , albinism, alkaptonuria, type 1 tyrosinaemia, nonketotic hyperglycinaemia, histidinaemia, homocystinuria, and maple syrup urine disease.
12. Protein Synthesis is the process in which cells build proteins. The term is sometimes used to refer only to protein translation but more often it refers to a multi-step process, beginning with amino acid synthesis and transcription of nuclear DNA into messenger RNA, which is then used as input to translation.
14. Protein Rich-Foods Beans As mentioned before, one half cup of beans contains as much protein as a 3 oz steak! Beans are a cheap, easy solution to just about any meal. Try black beans in a taco for lunch or a side of lima beans with your dinner. Eggs One egg contains 6 grams of protein. Eggs also contain many vital vitamins and minerals and all of the essential amino acids. An egg over-easy is a great breakfast or try a poached egg with spinach for dinner. Seafood Dairy Seafood is a great way to get healthy, high quality protein. Fishes such as salmon contain Omega-3 Fatty Acids, which is great for the heart and brain. Try salmon with brown rice and kale for an extremely healthy, protein charged dinner. Milk, cheese, and yogurt are all protein rich foods. Milk contains about 6.3 grams of high quality protein! Dairy products also contain calcium, which is great for strong bones and teeth. Add milk or yogurt to a smoothie and have some cubes of cheddar cheese as a snack- cheddar contains 25 grams of protein for every 100 grams.
15. Protein Rich-Foods Poultry Lean white meats such as turkey or chicken (without the skin) are high in protein low fat foods. Either a turkey sandwich or a chicken salad would be a perfect lunch to get you through the rest of the day without being hungry. Soy Soy is a great form of protein for vegans or vegetarians. Studies have shown that 25 grams of soy protein can reduce the risk of heart disease. Try edamame beans as a pre-dinner snack or a glass of soy milk in the morning with breakfast. Beef A lean cut of beef is an excellent source of high quality protein. Beef contains about 25 grams of protein and has zinc, iron, and vitamin B12. Try a lean cut of beef with crisp iceberg salad or oven roasted potatoes.
16. As 40% of the body’s dry matter is protein, so, after water, protein is the 2nd most important nutrient for the human body. Around 60% of the human body constitutes water & 40% is dry matter. This makes water the most essential nutrient for the human body. The word Protein has originated from the Greek word "Porto's" which means to come first. Only water is more important than proteins, as just a 8% deficit in your body’s water store could lead to serious eventualities if your body loses more than 14% of its Protein store, it could lead to severe health consequences. IMPORTANT FACTS Severe depletion of protein can lead to – • Loss of muscle mass causing physical weakness. • Fatigue • A weakened immune system. A s k t h e AbOuTpRoTeIn e G i u ! N S
