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.


How many ribosomes are needed for the production of a polypeptide containing thirty amino acids?

One ribosome is needed to synthesize a polypeptide containing thirty amino acids. The ribosome reads the mRNA and assembles the amino acids into a polypeptide chain according to the codons on the mRNA.


What is a beta-amino acid?

A beta-amino acid is a type of amino acid where the amino group is located on the beta carbon, rather than the alpha carbon, as seen in traditional amino acids. They are less common than alpha-amino acids but possess unique chemical and biological properties. Beta-amino acids can be found in certain natural products and have potential applications in drug development and materials science.


What substance make up protein chain?

Proteins are made up of long chains of amino acids, which are organic molecules containing an amino group, a carboxyl group, and a side chain. There are 20 different types of amino acids that can be combined in various sequences to form the diverse proteins found in living organisms.


What are the subunits of amino acids?

Amino acids are composed of an amino group, a carboxyl group, a hydrogen atom, and a side chain (R-group). The R-group varies among different amino acids and gives each amino acid its unique properties.

What will be molecular weight of peptide containing nine amino acids?

It is not predictable.There are 20 diffent amino acids.


What is the difference between amino acids and peptides?

Amino acids are the building blocks of proteins, consisting of a central carbon atom bound to an amino group, carboxyl group, hydrogen atom, and a side chain. Peptides are short chains of amino acids linked together by peptide bonds. Peptides can vary in length, with dipeptides containing two amino acids, tripeptides containing three, and so on.


What is nitrogen-containing building blocks of proteins?

Amino acids are the nitrogen-containing building blocks of proteins. They are essential for the synthesis of proteins in living organisms.


Why amino acid called alpha amino acid?

Amino acids are called alpha amino acids because the amino group (-NH2) is attached to the alpha carbon atom in the molecular structure of the amino acid. This alpha carbon is the carbon atom next to the carboxyl group (-COOH) in the amino acid molecule.


how many amino acids are there in one turn of alpha helix?

3.6 amino acid.


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 is the primary element in amino acids?

By looking at structures and formulas of amino acids one would have to say that carbon was the primary element making up amino acids.


What are amino acids?

Amino acids are the building blocks of proteins. There are 20 different amino acids that combine in various sequences to form different proteins in the body. Amino acids play crucial roles in processes like tissue repair, nutrient transport, and enzyme production.


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.
