Twenty-two amino acids are naturally incorporated into polypeptides and are called proteinogenic or natural amino acids. Of these, 20 are encoded by the universal genetic code. The remaining 2, selenocysteine and pyrrolysine, are incorporated into proteins by unique synthetic mechanisms. Selenocysteine is incorporated when the mRNA being translated includes a SECIS element, which causes the UGA codon to encode selenocysteine instead of a stop codon. Pyrrolysine is used by some methanogenic archaea in enzymes that they use to produce methane. It is coded for with the codon UAG, which is normally a stop codon in other organisms. This UAG codon is followed by a PYLIS downstream sequence.

Does proein contain nitrogen atoms?
Proteins are made from amino acids. All amino acids invariably have nitrogen. Thus each protein molecule contains atoms of nitrogen in it.
Amino acids can be distinguished from one another by?
Amino acids all have an amino group attached to them. There are 20 different amino groups, and therefore 20 different types of amino acids.
How many different types of amino acids exist?
There are 22 amino acids that humans require for life. however, there are hundreds of different kinds of amino acids.
How many different kinds of amino acids are essential amino acids?
9
What part of the amino acids varies from one amino acids to another?
The "R" group is different in different kinds of amino acids. The "R" group can be a number of different molecules that are attached to the alpha carbon.
How many amino acids are used in the synthesis of body protein?
They have varying numbers, as different amino acids form different polypetide chains, which form different amino acids in the way they become folded to suit their function
Do amino acids differ from fatty acids?
There are 20 different amino acids. They differ from one another because they all have different side chains.
Is protein and amino acids?
proteins are made up of different amino acids linked together
What is the minimum number of amino acids in protein?
there is only 20 amin acid in our bodies but we only use 11 of them
Total number of amino acids for the DNA sequence is?
There are 20 different amino acids in the DNA sequence
How many different amino acids are in glucose?
There are not any amino acids in glucoe because glucose is not a protein.
What is the theoretical number of chemically different dipeptides that may be assembled from 12 different types of amino acids?
the answer is C (144). The working is: 12^2 = 144. Here 12 is the no. of different amino acids and 2 is the no. of amino acids in the chain (its a dipeptide so, 2 amino acids).
