The identity and sequence of the amino acids present in a protein is its?first,second,third, fourth structure?

Its the primary structure...\nSecondary refers to the arrangement of protein residues in realtion to one another. alpha helix beta strand etc...\nTertiary is the big picture-what these things actaully look like. Quaternary structure is the comming together of of the teriary subunits.

Well, There are 20 different amino acids that are required for normal function to form proteins. They are divided into four different groups: non-polar amino acids, polar amino acids, aromatic amino acids and positively charged amino acids, depending on their side chains

Each organism has its own type of proteins. If you eat a chicken finger, and a beef burger and a fish sandwich, you have taken in fish, chicken, cow and wheat protein. Your body digests it by separating the proteins into amino acids. These then are put back together into human proteins. Theproteins and all different. proteins of the original meat or plant are different colors and different amino acids. The essential amino acids we need are obtained best by a variety of proteins. Lobster, pig, lamb, clam, soy, nut, are all

During protein synthesis, 20 different amino acids can be incorporated in proteins. After translation, the posttranslational modification (PTM) of amino acids extends the range of functions of the protein by attaching to it other biochemical functional groups such as acetate, phosphate, various lipids and carbohydrates, by changing the chemical nature of an amino acid (e.g. citrullination) or by making structural changes, like the formation of disulfide bridges.\n\nPTMs involving addition include:\n\nacetylation, the addition of an acetyl group, usually at the N-terminus of the protein \nalkylation, the addition of an alkyl group (e.g. methyl, ethyl) \nmethylation the addition of a methyl group, usually at lysine or arginine residues. (This is a type of alkylation.) \nbiotinylation, acylation of conserved lysine residues with a biotin appendage \nglutamylation, covalent linkage of glutamic acid residues to tubulin and some other proteins. \nglycylation, covalent linkage of one to more than 40 glycine residues to the tubulin C-terminal tail \nglycosylation, the addition of a glycosyl group to either asparagine, hydroxylysine, serine, or threonine, resulting in a glycoprotein \nisoprenylation, the addition of an isoprenoid group (e.g. farnesol and geranylgeraniol) \nlipoylation, attachment of a lipoate functionality \nphosphopantetheinylation, the addition of a 4'-phosphopantetheinyl moiety from coenzyme A, as in fatty acid, polyketide, non-ribosomal peptide and leucine biosynthesis \nphosphorylation, the addition of a phosphate group, usually to serine, tyrosine, threonine or histidine \nsulfation, the addition of a sulfate group to a tyrosine.

yes and no....  Proteins are made up of amino acids, of which there are about 20.  Long strings of AA's are called polypeptides, and proteins have secondary, tertiary and quaternary structure, which are respectively, order of AA, shape of protein as a whole (how folded etc.), and combination with other protein subunits.  Proteins are not DNA, they are made corresponding to the DNA sequence from an RNA intermediate.  Proteins do essentially all work within a cell, from activating and repressing transcription to acting as membrane channels and secondary messengers.

Adding a few drops of copper sulphate solution to a protein solution, followed by a few drops of sodium hydroxide solution produces a purple/dark blue precipitate.\n\nIf any protein originally present in the solution has already been changed into amino acids by a protease enzyme for instance, then the precipitate will not appear.\n\nThat should give you a clue about molecules of amino acids compared to molecules of protein. (You might have to remind yourself of the structure of amino acids and proteins.)

To get the right answer you need to ask the right question. \n\nWhat you are looking for is tools and techniques for Protein Structure Modeling. \n\nJust type "Protein Structure Modeling" in Google and you should get a bazillion hits!\n\nHere are a few sites to get you going anyway:

You will still have to read the info at the links below as it is "assumed that you have a rudimentary understanding of basic concepts of protein and nucleic acid structure, as well as enzyme kinetics and mechanisms."\n\nI digress to say that "amino acids are the principal building blocks of proteins and enzymes. They are incorporated into proteins by transfer RNA according to the genetic code while messenger RNA is being decoded by ribosomes. During and after the final assembly of a protein, the amino acid content dictates the spatial and biochemical properties of the protein or enzyme."\n\n"The amino acid backbone determines the primary sequence of a protein, but the nature of the side chains determines the protein's properties. Amino acid side chains can be polar, non-polar, or practically neutral. Polar side chains tend to be present on the surface of a protein where they can interact with the aqueous environment found in cells. On the other hand, non-polar amino acids tend to reside within the center of the protein where they can interact with similar non-polar neighbors. This can create a hydrophobic region within an enzyme where chemical reactions can be conducted in a non-polar atmosphere. Likewise, enzymes can also have polar amino acid substituents within the active site that provide a polar region in which to conduct biochemical synthesis."\n\n\n1. Structure of Amino Acids\n2.

Proteins are composed of one or more polypeptides and polypeptides are a sequence of amino acids. every polypeptide is coded by a particular gene. during polypeptide synthesis, dna unwinds and one strand acts as a template (which is possible because of the complementary base pairs). spare bases are used to form  messenger RNA (mRNA) using the template. the mRNA moves out of the nucleus and into the cytoplasm towards the ribosomes. at the ribosomes, the polypeptide is actually synthesised. tRNA consists of an anticodon (sequence of three bases) and an amino acid. It matches its anticodon to the appropriate codon (sequence of three bases) to the mRNA. this continues with different tRNA molecules until a sequence of amino acids are formed- thus creating a polypeptide. \n\nSo, since proteins consists of polypeptides which are formed by the information in genes, in essence, a protein's structure and function is determined heavily by the gene that synthesises it.

Proteins:\nAny of a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur and are composed of one or more chains of amino acids. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary for the proper functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.\n\nNucleic Acid:\nAny of a group of organic substances found in the chromosomes of living cells and viruses that play a central role in the storage and replication of hereditary information and in the expression of this information through protein synthesis. In most organisms, nucleic acids occur in combination with proteins; the combined substances are called nucleoproteins. Nucleic acid molecules are complex chains of varying length. The two chief types of nucleic acids are DNA (deoxyribonucleic acid), which carries the hereditary information from generation to generation, and RNA (ribonucleic acid), which delivers the instructions coded in this information to the cell's protein manufacturing sites.\n\nHope tht helped

Go to "protein" on wikipedia ( put, protein, in address bar ) then scroll down to "synthesis", for the process. It is too  long a story for my typing skills. The wiki article is not too technical.
