What is the relative size of amino acid R chains and how can it be determined?

In summary, amino acids have an average molecular weight of 110 Daltons and a size of about 1.5 angstroms in diameter. The size of amino acids is crucial in determining the structure and function of proteins. It also plays a role in the polarity of amino acids, with larger ones more likely to have polar or charged side chains. Amino acids are not all the same size, with differences in their side chains. The size of amino acids does not directly impact their role in protein synthesis, but it does affect the structure and function of proteins, which can impact their role in cellular processes.

I need to compare amino acid R chains relative to each other. Is there a way to figure this out with the chemical forumula or am i supposed to glance over the stuctures?

Also I am finding mixed messages about polarity for each. Are these correct?

thanks

Glycine .49 .26 Nonpolar
Tryptophan .80 .66 Nonpolar H-bond
Lysine .31 .14 Polar
Aspartic Acid .42 .24 Polar
Serine .44 .27 Polar
Alanine .88 .38 Nonpolar
Leucine .76 .73 Nonpolar
tyrosine .69 .45 Non Polar

No idea about polarities, yes you need structures.
 

1. What is the relative size of amino acids?

The relative size of amino acids can vary depending on the specific amino acid. However, on average, amino acids have a molecular weight of around 110 Daltons and a size of about 1.5 angstroms in diameter.

2. How does the size of amino acids affect protein structure?

The size of amino acids plays a crucial role in determining the overall structure and function of a protein. The size of each amino acid affects the folding and bonding of the protein, ultimately determining its shape and ability to interact with other molecules.

3. How does the size of amino acids relate to their polarity?

The size of an amino acid is not directly related to its polarity. However, larger amino acids are more likely to have polar or charged side chains, while smaller amino acids tend to have nonpolar side chains. This difference in polarity can affect the interactions between amino acids in a protein.

4. Are all amino acids the same size?

No, all amino acids are not the same size. Amino acids can vary in size due to differences in their side chains. For example, alanine has a small, nonpolar side chain, while phenylalanine has a larger, aromatic side chain.

5. How does the size of amino acids impact their role in protein synthesis?

The size of amino acids does not directly impact their role in protein synthesis. However, the sequence and size of amino acids in a protein determine its structure and function, which can ultimately affect its role in various cellular processes.
