3.6 amino acid.
This is quite simple. Using stoichiometry to keep track of units, simply take the number of amino acids in the particular alpha helix and multiply by 15 angstroms. This is the length the alpha helix is advanced along the length axis by each additional A.A. For a beta helix it become more difficult however and you must know how many sheets you are taking into account.
Fructose is a saccharide, and is not constructed of amino acids
There are 20 common amino acids found in proteins that are used by cells to synthesize proteins. These amino acids are the building blocks of proteins and are linked together in a specific sequence to form the unique three-dimensional structures of proteins.
The smaller building blocks of protein are called amino acids. Amino acids are molecules containing a carboxyl group (-COOH), an amino group (-NH2) and a variable or "R" group, which is what makes the different types of amino acids. There are 20 different amino acids, but they can be arranged into many different sequences, which explains why so many different proteins exist. Amino acids form long chains called polypeptide chains. These chains can then fold into a secondary structure, either an alpha helix or a beta pleated sheet. Then that continues to be folded into the tertiary structure, which is formed by four different types of bonds: hydrogen bonds, hydrophobic interactions, ionic bonding and disulfide bridges. Tertiary folding can have two shapes, coils or barrels. Finally there is quaternary structure, which contains multiple polypeptide chains folded into rounded shapes. Quaternary structure has two different shapes, fibrous and globular.
Amino acids do not have hydrogen bonds. They only have an alpha corbon atom connected to 4 groups namely: Hydrogen A variable R group An amide group A carboxyl group

amino acids?? 20 amino acids

Proteins have a building blocks as amino acids and I think there are about 20 essential amino acids in humans. The structure depends on the series and sequence of the polypeptides arranged which are joined together by covalent bonds and ultimately form a protein. You will know more about it when you take bio or chemistry classes in your school or college respectively.

There are 22 "standard" amino acids, although many others exist
An amino acid is a molecule containing nitrogen, carbon and hydrogen as well as an 'R' group which can contain many different elements. They are often joined together in a polypeptide chain which is then folded into alpha-helix and beta pleated sheet. It is then folded again into the tertiary structure and many of these tertiary structures come together to form proteins like haemoglobin or enzymes.

100 amino acids long
A pentapeptide contains five (penta-) amino acids.
Polypeptides are chains of amino acids linked by peptide bonds.
There is a great degree of variability in the number of amino acids per protein. An answer to another question on WikiAnswers lists the shortest protein as 8 amino acids. According to the National Center for Biotechnology Information, the longest protein found in a sequenced genome is a "parallel beta-helix repeat-containing protein" in the organism Chlorobium chlorochromatii, this protein is 36,805 amino acids long.A protein may consist of as many as 5,000 amino acid molecules.
