There is Histone and non-histone protein associated with the DNA.histone are low molecular protein made up of basic amino acids.Non histone are high molecular proteins and made up of basic amino acids.

This is not a pure biology question. Should be bio-chemistry.

protein is albumin\n\namino acid is glycine

All proteins are made of amino acids, so "amino acid protein" is redundant. And it's 4 kcals/g.

Proteins are large molecules that are made from amino acids, which are small molecules.

All other common amino acids have a primary amino group. The primary amino group is essential for the formation of the purple chromophore.\nProline has a secondary amino group so the reaction is different\n\nHave a look at the link below

There are more than 10 types of amino acids and each protein molecule is made up of 1000s of amino acids.  This is one reason that constitute the large variety of proteins.  \nAnother reason is the protein folding.  Each amino acid has different bonding ability which determines the protein bonding which then determines the shape of the each protein.

In proteins and peptides the nitrogen group is reacted with the carboxylic group beside it, with only the very last (or very first) amino acid in the protein/peptide chain being free, where as in amino acids all of the amine groups are free.

No.\n\nBy definition (IMO), macromolecules contain many __more__ covalent bonds than non-covalent bonds.  The covalent bonds are also __stronger__ than the non-covalent bonds.\n\nI will add that the realm where non-covalent bonds are most interesting is at the larger scale of structure; assembling lipids, carbohydrates and proteins (held together by non-covalent bonds) into membranes, ribosomes, mitochondria, cell walls, blood vessels, bones .... bodies ... trees ...\n\nYou get the picture :-)

Amino acid is One of the 20 building blocks of protein. The sequence of amino acids in a protein and, hence, the function of that protein are determined by the genetic code in the DNA. \n\nAmino acids are molecules that (in technical terms) contain a basic amino (NH2) group, an acidic carboxyl (COOH) group and a side chain attached to an alpha carbon atom. \n\nThe 20 amino acids are alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, and valine. \n\nMost dietitians say it is unhealthy for people but it depends on blood count and things like that you should ask you physician or doctor before you do anything

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.

Amino acid is any molecule that contains both amine and carboxlic acid.  Amino acid is the building block of protein.\n\nVisit http://en.wikipedia.org/wiki/Amino_acid http://en.wikipedia.org/wiki/Amine http://en.wikipedia.org/wiki/Carboxylic_acid

Amino acids.  All proteins are combinations of only these twenty amino acids, which are known as the building blocks of proteins.  The listed source can give you a list of the twenty amino acids.

At physiological pH most of the -COOH of amino acids are deprotonated (-COO-) and -NH2 protonated (-NH3+).\nIf you increase the pH then the -COO- will remain as such but the -NH3+ will lose the proton. -NH3+ can act only as an H-donor for an H-bond so such a bond will be broken. However if the geometry and number of interacting partners allow it it could be replaced by another H of the same -NH2 group.\n\nTyrosine has pKa around 10, so if you go to extremely basic pH it will be deprotonated and thus it will not be able to act anymore as an H-donor for a hydrogen bond and the bond will break. If however it was acting as a lone pair donor, the bond will become even stronger.\n\nGenerally when the pH change (extremely basic or acidic) causes changes in the charge of the group can but not necessarily breaks H-bonds. An important note: even if the H-bonds are not completely broken there will be rearrangement (some bonds might break and others form as the some H-donors become H-acceptors and vice versa) changing the conformation/folding of the protein.\n\nFor sure the effect of pH on ionic bonds is far greater than that on H-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

Aren't you confusing glycine with glutamate?\n\nAnyhow, here is a place that sells glycine.
