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.

Proteins contain what kind of acids?
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.
What is the name of subunit structure of proteins?
The subunits that make up proteins in most living things are twenty different amino acids. Google amino acid at wiki.
Amino acids are monomers used to build what?
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.
What is the number of different amino acids from which all proteins in living things are made?
there are only twenty different amino acid
Is nitrogen an essential component of proteins?
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.
How proteins differ?
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.
How many amino acid are there in all?
There are 20 standard amino acids that are commonly found in proteins. These amino acids can be combined in different sequences to create a wide variety of proteins with diverse structures and functions.
Which amino acid is most common in all three animals?
The amino acid that is most common in all three animals (humans, dogs, and birds) is glycine. Glycine is the simplest amino acid with a hydrogen atom as its side chain, making it a versatile component of proteins.
What is a sentence using the word amino acid?
Amino Acids are the building blocks of life. Cells use amino acids to build proteins such as enzymes, muscles.
How many types of amino acids are available to construct all the proteins in a human body?
There are 20 standard amino acids. A few proteins have other amino acids but these are usually derived from the 20 standard amino acids.
Where doesaminocid come from?
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.
Which of the following refers to the amino acid sequence of proteins?
In order to answer this question, you must, and prpbably do have the codon sequences of the RNA or DNA, and a chart saying what each codon codes for in terms of amino acids. The mRNA from transcription is what the sheet probably has on it, with each codon contained therin signaling a certain amino acid. If you can post the sequence or something like that, then ill sertainly answer it for you.
