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.

This is sort of like asking how many beads make up a necklace. There is no set answer.

2 amino acids= Dipeptide

3 amino acids= Tripeptide

and i say 4+ amino acids= Polypeptide

There are twenty amino acids [of the gazzillions available] that have been Bio-Selected to partake in Life's processes - with two alternates.

There are 20 common amino acids that make up protein. The instructions for the sequence of amino acids is carried on mRNA. These instructions are then translated by the ribosomes to make protein.

There are 20 different types of amino acids that make up protein. These amino acids are combined in various ways to produce up to 100,000 kinds of proteins.

Depend upon the organism, Here some examples:

Pepsin from:

  1. humans: 388 amino acid residues;
  2. bovine: 372;
  3. mouse: 387.

What is a protein molecule made of and how many of these are there?

A protein is a chain of amino acids. Small chains of amino acids are called polypeptides. If the chain is over 20 amino acids long, it is called a protein.


What is a protein monomer?

amino acids are the monomers for protein


How many amino acids make up a protein?

There are nine essential amino acids. A protein is considered to be complete if it contains all nine of these amino acids.


How many amino acids are there that make up proteins?

The number of amino acids/protein differ largely and is characteristic for each protein separately. A protein is composed of amino acids, and the function of the protein depends of the type and order of the amino acids. Because amino acids can be arranged in many different combinations, it's possible for your body to make thousands of different kinds of protein from just the same 20 amino acids.The simplest protein of life, ribonuclease, contains 124 amino acids. The "average" protein, though, contains several thousand amino acids, but those several thousand comprised only about 20 different kinds of amino acids.


How many amino acids long is a typical human protein?

100 amino acids long


How many amino acids completes protein?

The term "complete protein" refers to amino acids, the building blocks of protein. A protein must contain all nine of these essential amino acids in roughly equal amounts.


Do enzymes primarily form from amino acids?

Yes. Enzymes are made of protein basically and protein is made from many amino acids.


What are numerous amino acids bonded together called?

This would be called a protein if there are many amino acids chained together.


Subunit of Protein?

Amino acids


What is a protein made of?

A protein molecule is a long chain of amino acids. There are 22 different amino acids and their chemical properties determine the shape of the protein which determines the function of the protein.


Monomer of proteins?

Amino acids.


Can 2 amino acids form a protein?

No. A protein is defined by its function, as much as its structure. A chain of two amino acids would have no protein-like functions. The smallest known protein is a chain of 20 amino acids, but most have many more, and sometimes consist of multiple chains of amino acids.
