the pitch of a alpha helix is o.54 nm , that is the distance between two points at the same horizontal position in a helix if is held up right. there are 3.6 aa per turn.
therefore if there are 78 aa then Lengthhelix= (78 /3.6)* 0.54 nm

What Organic molecule composed of long chains of amino acids?
This description applies to all alpha amino acids except for glycine.The amino acids found in cells of organisms are alpha amino acids. The carbon-containing group is a side chain, often symbolized by R.The general formula for amino acids isR-CH(NH2).COOHIn glycine R = H, but in all other amino acids R represents a side chain containing, among other elements, one or more carbon atoms.
What small units join together to form proteins?
Mainly alpha-amino acids. Some proteins have cofactors which are not amino acids.
What are the subunits of amino acids?
There are no subunits to amino acids others than atoms. Aminos acids are small molecules containing carbon, hydrogen, oxygen, nitrogen and sometimes sulfur. Amino acids are the subunits of polypeptides and a few of these can combine to form proteins.
How many amino acids are in DNA and Proteins?
DNA contains no amino acids, it contains nucleic acids. Proteins can contain from 2 amino acids to tens of thousands.
How many ribosomes are needed for the production of a polypeptide containing thirty amino acids?
One.

What will be molecular weight of peptide containing nine amino acids?
It is not predictable.There are 20 diffent amino acids.
how many amino acids are there in one turn of alpha helix?
3.6 amino acid.
What is nitrogen-containing building blocks of proteins?
Amino acids
What small units join together to form proteins?
Mainly alpha-amino acids. Some proteins have cofactors which are not amino acids.
Is creatine a compound from amino acids?
No, not really. It is an acid, and it does contain an amino group, but it is not generally considered an amino acid per se. The amino acids we generally speak of are alpha amino acids, and creatine is NOT one of those. When you ask if it is "from amino acids", then the answer would be YES. It is made in the body from several amino acids, such as methionine, glycine and arginine.
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.
What are amino acids?
Amino acids are organic molecules that contain both a basic amino group and an acidic carboxyl group linked to an alpha carbon. The alpha-amino acids, in which the amino group is attached to the alpha carbon, are the building blocks of peptides and proteins. The amino acids are commonly classified either as a) neutral, basic, or acidic, or as b) nonpolar, polar and uncharged, or polar and charged; the presence or absence of a charge on the amino acids refers to that at pH 7.0
What is the difference between amino acids and other acids?
Amino acids are molecules containing both amine and carboxyl functional groups. 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.
What funtional group will give a positive results with ninhydrin reagents?
Amino acids with a free -NH2 group and proteins containing free amino acids
Which two amino acids contain a sulfur atom?
The sulfur containing amino acids that are found in proteins are cysteine and methionine.
What are the subunits of amino acids?
There are no subunits to amino acids others than atoms. Aminos acids are small molecules containing carbon, hydrogen, oxygen, nitrogen and sometimes sulfur. Amino acids are the subunits of polypeptides and a few of these can combine to form proteins.
