''''protein''' Protein is a high molecular weight composition compound composed of amino acids linked together by a peptide bond. Protein is necessary in the composition and function of all living cells and even viruses. <gallery> https://www.google.jo/imgres?imgurl=http%3A%2F%2Fwww.azom.com%2Fimages%2FArticle_Images%2FImageForArticle_11177(4).jpg&imgrefurl=http%3A%2F%2Fwww.azom.com%2Farticle.aspx%3FArticleID%3D11177&docid=VyTkAs6cnoHiOM&tbnid=8WfHvgRqdmtF2M%3A&vet=10ahUKEwj_7572rrrTAhVOYlAKHUMIAAoQMwg9KAkwCQ..i&w=500&h=375&bih=794&biw=1440&q=protein%20structure&ved=0ahUKEwj_7572rrrTAhVOYlAKHUMIAAoQMwg9KAkwCQ&iact=mrc&uact=8 </gallery> Protein synthesis Many proteins form enzymes or proteinuria units involved in the synthesis of enzymes. Protein also plays other structural or mechanical roles, such as the formation of struts and joints within the cytoskeleton. Protein plays other vital functions. It is an important member of the immune response, storage and transport of biomolecules and a source of amino acids for organisms that can not form these amino acids themselves. Proteins are also one of the huge biomolecules along with the various sugars, fats and nucleic acids. These massive biomolecules form the components of the living material. Protein structure: [edit source] Primary structure of protein Protein is composed of a number of amino acids (substances containing a group of carboxylic acid and amino acid NH2-base and therefore have a neutral effect) These acids are linked with each other chemical bonds known as peptide links, and then form this initial form to secondary, For other bonds - hydrogen and ionic - maintain the form of protein either globular or globular fibrous. The protein consists of a peptide series of amino acid binding that later wraps up to form a unique three-dimensional structure (each protein has a different structure than other proteins. This structure is called the original state of the protein and is determined by the order of the amino acids in the bonding process that forms the protein chains.) Primary structure: Determined by the sequence of amino acids. Secondary structure: consists of secondary structures consisting of the wrapping of peptide chains on each other in the form of alpha and beta plaques.https://www.google.jo/imgres?imgurl=http%3A%2F%2Falevelnotes.com%2Fcontent_images%2F600px-1GZX_Haemoglobin.png&imgrefurl=http%3A%2F%2Falevelnotes.com%2Fprotein-structure%2F61&docid=oo3PJsCKK36HXM&tbnid=Dvu-PpzepE-JVM%3A&vet=10ahUKEwj_7572rrrTAhVOYlAKHUMIAAoQMwhXKBowGg..i&w=600&h=600&bih=794&biw=1440&q=protein%20structure&ved=0ahUKEwj_7572rrrTAhVOYlAKHUMIAAoQMwhXKBowGg&iact=mrc&uact=8 Tissue structure: Determines the form of the final protein, consisting of the assembly of secondary protein structures (alpha and beta-platelets) by non-symbiotic physical forces to give the final form of protein Rape structure: This term is usually used to denote the structure formed by a combination of two or more bipolar sequences in the so-called protein unit, eg hemoglobin. The primary, secondary, and tertiary structures are usually associated with proteins with folded structures, whereas the quadratic structure is usually related to proteins or self-assembly proteins. Protein structure is not constant at all but changes to perform its various functions and to achieve this structural change occurs a change in the links of the structure of the third and quaternary, so we call these structures and the third quartile chemical configurations and changes in the changes in the form of conformational changes [1]. Chemical steps in protein synthesis: [edit source] The chemical reaction phases that occur when manufacturing the protein molecule are as follows: Each amino acid activates a chemical process in which ATP binds with amino acid to form an AMP complex with the amino acid producing high phosphate bonds in this process. The activated amino acid, which has excessive energy with the RNA, binds its specific carrier to generate an acid-tRNA complex, while releasing the adenosine monohydrate. RNA binds the carrier of the amino acid complex to the messenger RNA molecule in the ribosome where the transient RNA code corresponds to the specific RNA symbol in the messenger RNA, thus binding the amino acids in a suitable format to form the protein molecule. It is then formed by the effect of the enzyme peptide Nerranzferase - one of the proteins in the ribosome - peptide bonds between successive amino acids and continuously added to the protein chain. These chemical events require the energy of two additional high-energy phosphate bonds to generate four high-energy bonds that are used for each amino acid added to the protein chain [2]. The process of protein synthesis is one of the largest energy consumption processes in the cell. Pseudo-link: [edit source] The successive amino acids in the protein chain combine with each other according to a typical reaction. The hydroxyxyl root is removed from the COOH portion of an amino acid in this chemical process, while one hydrogen is removed from the NH2 molecule of the other amino acid. The two sites combine to form a single molecule, called the peptide link [3]. Posts: [edit] Mechanism of protein regulation: [edit source] Proteins can bind various chemical molecules and metal electrodes into special structures in their structure called Bindingsites. However, the proteins are characterized by a high chemical uptake towards the compounds to which they bind. The compounds that bind to proteins are called ligand ligands, and the bonding strength of a gene-protein is one of the characteristics of the link site called affinity. Since proteins interfere with every process within living cells, control of biological processes can be done by controlling the effectiveness of these proteins. This regulation of all proteins can be done by the form or concentration of proteins: Allosteric modulation Covalent modulation. What are the main compounds that contribute to protein synthesis? [Edit] The following compounds contribute to the synthesis of proteins in the living cell: DNA, RNA, RNA, mRNA, Reproduction of genetic material Genetic information in genes does not convert directly into proteins where the gene copies its messenger RNA, carrying the gene message in the nucleotide language (5 to 3) to the messenger RNA, The gene chain is duplicated or encoded. Properties of proteins: [edit source] Protein is of great importance in terms of its vital value because it contains vital amino acids that are beneficial for growth and health, and are the most suitable nutrients for building tissues. Proteins are essential for muscle formation, the most effective part of the body to burn calories. Proteins are found in meat, dairy products, and less in grains and vegetables. You have to eat enough protein. Examples of proteins: [edit source] Albumin (egg white protein). Glybophenolin (-Kreen-in blood and milk).
