How can there be so many different types of proteins when there are only 23 different amino acids?

Proteins are really very diverse in terms of their amino acid composition. Proteins are coded in the DNA, the sequence of DNA (A, T, G, C) determines the fate of amino acids that join together to form a protein. so the bases of the DNA can make a diverse group of proteins. normally proteins from a same family (for example antibodies or kinases) share a conserved domains or amino acids although they differ in their specificity and function.

It is not just the amino acids in a protein that determine the protein structure and function but also the order, which is responsible for interactions formed during the folding of the protein from a single long chain to its 3D structure. A single amino acid change in a protein of 400 amino acids can change the protein conformation.

How many monomers of proteins exist?
20
What are the smaller molecules called that make a protein?
Proteins are polymers of amino acids. The instructions for protein synthesis are contained within the genes (on DNA). This instructions are read from an mRNA at the ribosomes to produce the correct sequence of amino acids - a protein.
What types of bonds and monomers form proteins?
The monomers are amino acids and the bonds are called peptide bonds.
What is the basic difference between the different types of amino acids A Presence of oxygen B Side chains C Types of bonds D Presence of nitrogen?
Different amino acids have different side chains.
How many amino acids could be found in the human body?
There are twenty common protein amino acids in your body, of which half can be formed in the cells. The remainder need to be consumed in our diet, as our body cannot make them, yet they are still vital. There are 2 other amino acids very ocassionally used in proteins (only one in humans) meaning that are 21 different protein amino acids in humans. Some biological pathways use other types of amino acids not found in proteins. There are at least six additional ones found in humans, but it would be difficult to determine an exact number.
How are proteins distinguished from one another?
Different types of proteins are formed by the bonding of different types of amino acids. There are typically four types of amino acids that make up a protein.
Consequences of proteins containing different numbers and different types of amino acids?
As proteins contain different numbers and types of amino acids they are different shapes and have different affinities for water and lipids.
Instructions for assembling amino acids into proteins?
Proteins are made from amino acids, there are different types of proteins in our body ane the order of the amino acids determines the type of amino acid cus it sure helped me :)
Although there are a limited number of amino acids many different types of proteins exist because the?
sequence and number of amino acids is different
What basic unit do proteins have 20 types of?
Different proteins have different numbers of subunits. For example, IgM, an immunoglobulin, has six subunits.
How many monomers of proteins exist?
20
Why is there infinite variety possible in proteins?
Different 3D shapes, different number of proteins, different types of amino acids, and different sequences.
What are the different types and functions of proteins determined by?
They are determined by the sequence and number of amino acids.
How many types of amino acids are available to construct all the proteins in a human body?
There are 20 standard amino acids. A few proteins have other amino acids but these are usually derived from the 20 standard amino acids.
What is the subunit that proteints are made from?
the subunits that proteins are made from are called amino acids , there are about 20 common amino acids that are used in the synthesis of proteins in humans , and proteins differ in the number , types , and sequence of amino acids .
Do amino acids have protein?
Amino acids are the building blocks of proteins. Proteins are simply chains of amino acids. I think you meant to ask do proteins have amino acids. Amino acids as the name indicates (Amino) have amine groups, carboxylic acid groups and a side chain that varies depending on the amino acid (20 differnet types).
Why is it possible to have thousands of different types of proteins with only 20 amino acids?
There are many different combinations of amino acids and proteins and peptide bonds.
