In chemistry, an amino acid is a molecule containing both amine and carboxyl functional groups. These molecules are particularly important in biochemistry, where this term refers to alpha-amino acids with the general formula H2NCHRCOOH, where R is an organic substituent Amino acids are critical to life, and have a variety of roles in metabolism. One particularly important function is as the building blocks of proteins, which are linear chains of amino acids. http://en.wikipedia.org/wiki/Amino_acid === === The answerer to this question did not actually answer it. The question is asking what amino acid do all proteins start with, not for the definition of an amino acid. The answer is methionine, because the gene for every protein has a start codon in the mRNA of AUG, and AUG codes for the amino acid methionine.
give the Pokemon irons, calcium proteins and all that stuff
All spiders start with the letter 'a' - they are all Arachnids.
All of the countries of Europe that start with M are;MacedoniaMaltaMoldovaMonacoMontenegro
All of the ones that start with the letter k.

All proteins are made up of amino acids joined together by peptide bonds. An amino acid has a carboxylic acid functional group and an amine group. Some of the amino acids (such as aspartic acid and glutamic acid) has an extra carboxylic acid functional group in its side chain.
A monomer is a small molecule that can easily bind to others. Amino acids are monomers, because they bond together to form proteins, which are polymers. Another example of a monomer is glucose, but it can bind to form polymers like cellulose.
Proteins differ each other in their amino acid composition and the number of amino acids that form it. Not all the proteins are the same, although they are all made up of amino acids. the sequence of amino acids is determined by the mRNA which is transcribed by DNA in the nucleus.
If the R group on the amino acid constituents of proteins have a fluorine, oxygen or nitrogen linkage to a hydrogen the yes. An amide, NH3, is on the base of all amino acids. Check your amino acid structures.
The subunits that make up proteins in most living things are twenty different amino acids. Google amino acid at wiki.
there are only twenty different amino acid
Genetic's determines what proteins are produced. Don't mix up proteins with amino acids; Proteins are made from amino acids and Amino acids are the monomers (building blocks) for proteins. In the triplet code an DNA strand is read like a book; for example: AT ] CG ] Amino acid Called Anmino acid lettered 'P'. TA ] PKUMIPPQ - All the amino acids join to form a protein (polypeptide).
All proteins are compounds comprised of amino acids. Amino acids contain amine (-NH2) and carboxylic acid (-COOH) groups. Nitrogen is an essential component of the amine group in all proteins.
The most limiting amino acid in cereal grain proteins (wheat, rice, corn) is lysine. The limiting amino acid in legume protein (peas and beans) is methionine.
Proteins are made up of amino acids, which are made up of amines (NH2) and carboxyls (COOH). They are joined by peptide bonds. Examples of functional categories of proteins includes Contractile proteins, regulatory proteins, structural proteins, transport proteins, catalytic proteins and immunological proteins
Do you mean Amino Acid? Amino Acids are proteins, and the body cannot produce them itself. There are Complete Proteins which have all 27 of the essential Amino Acids in them. Examples would be meat, fish, eggs, dairy products. Then there are Incomplete Proteins which have some, but not all, of the 27 essential amino acids, and they are vegetable in origin and examples include beans and nuts.
Regardless of the countless arrangements of the tewnty plus amino acids, all proteins contain the amine group (-NH2) and the carboxylic group (-COOH). These groups or monomers appear in every amino acid.
