What is an amino-peptide complex?
457527
Amino acids are organic molecules with amino groups (-NH2) and acidic groups (-COOH).  When the amino group (-NH2) of one amino acid reacts with the acidic group (-COOH) of another, the bond is called a "peptide" bond (IIRC.)\n\nIf you link a small number of amino acids in this way, the product is often just called a "peptide".  The better term is "oligopeptide", as "oligo" comes from Greek, meaning "few".\n\nReally long peptides are called polypeptides or proteins.  ("poly" comes from Greek, too, meaning "many")\n\nSome proteins have different polypeptides that stick together, held by weaker forces such as electrostatic attraction.\n\nDoes that help?

Which one hahaha. There are many! There are over 20^100 possible combinations of amino acids which make up protiens. And in general we dont look at the molecular formula because it doesnt tell us as much as the amino acid residues. \n\nLys-Arg-Cys ....

Amino acids.\n\nOH, I thought you asked what they are made OF. Sorry - Ribosomes!

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.

Many of the orignal studies were based on mutations in bacteria which halt growth or have other phenotypes, where it was found that mutations could be labeled into several groups, and that if bacteria from different groups mated, then the phenotype is restored.  From this it was deduced that the mutations were in coding regions for proteins that exist in a network ie A to B to C, and usually proteins like A and B were in a complex.  Today its a large part of cell and molecular biology to figure out if proteins are in complexes, and what the complex does.  Its not necessarily important that A and B are in a complex, but what that complex does; since that is the proteni function in cells.  So if A and C are in a complex, the complex has a certain function.  if B and C are in a complex, then there is a different function.  Drug companies have been exploiting this type of knowledge for a long time, but what is more impt is the understanding of how proteins interact with other proteins, and how they regulate cellular functions.  Once this is understood, then drugs can be rationaly designed.  Even then, however, it's not possible to guarantee patient efficacy.  \n\nWe just had a great lecture by Gordon Mills, an expert in the PTEN protein pathway, and he talked about the dozens of drugs made against various members of this pathway, and noted that so far none of these drugs are effective in patients, although they work in the test tube and in mice.  So, drug discovery is a very difficult issue and takes billions of dollars for one drug to be delivered to market (and 10 years or more).

Proteins having nucleic acids as prosthetic groups, and thus yielding nucleic acids (or their cleavage products) as well as amino acids on hydrolytic cleav.\n\nor\n\nAny of a group of complexes composed of protein and nucleic acid and found in the nuclei and cytoplasm of all living cells, as in chromatin and ribosomes, and in viruses.

That guy is wrong.  It is not DNA.  DNA is a double-helix composed of a sugar-phosphate backbone with a nucleic acid on each side of the "ladder."\n\nA polypeptide chain is what you have when you join amino acids.\nIf you join enough of them (usually many) you have a protein.\n\nProtein and polypeptide chain are almost synonomous, but proteins can have very lentgthy, interacting 3-dimensional structures, and the are made of polypeptide chains composed of amino acids joined by polypeptide bonds.

yeah, i agree with what Smokeybon said and some examples of those amino acids are proline, histidine and others look at some shampoo bottles

usually protein with some metallic ions

All answers are correct. The primary aminoacid sequence is changed which may have implications for the structure and funtion of the protein

Electrophoresis is a process of seperation of molecules based on electric charge they possess using mild electric field in an electrolyte medium. Protein peptides for eg. can be separated by breaking the long protein chain using denaturing chemical such as beta-mercaptoethanol and treated with a detergent such as sodium dodycyl sulphate to render net negative charge to the molecules (peptides so broken). Now, sepration takesplace mainly on the basis of molecular weight of the peptide. U can use standard peptides/proteins to get a separation calibration curve. These are available commercially.

All types of Ribosomes make amino acids.  Many amino acids are called proteins. Once the proteins are made, they are traveled to the ER, endoplasmic reticulum.  Then the ER delivers the proteins to the other organelles of the cell.  I hope this answers your answer.  I also know how the ribosomes make the protein. =)

Arginine being an aminoacid has a COOH terminus and an NH3 terminus.\nat Ph 7(also called "isoelectric Ph"),all aminoacids become amphoteric.ie,they have both +ve and -ve charge due to ionization of COOH into COO- and NH3 into NH3+.so,when it is protonated,obviously it's COO- group gets neutralized(since proton is added)and gets converted to COOH and now arginine is left with the +vely charged NH3+ grp.THUS it acts as a base.
