leucine has a nonpolar side chain while serine has a polar side chain
It is non polar. In amino acids, "polar" or "nonpolar" refers specifically to the side chain; the molecule as a whole is definitely polar, but leucine's side chain is a hydrocarbon with no polar groups.
The functional group of serine is a hydroxyl group (-OH) attached to its side chain. This hydroxyl group allows serine to participate in hydrogen bonding and chemical reactions, making it an important amino acid in protein structure and enzyme catalysis.
The word "amino acid" has to my knowledge no chemical name. However below are the names of the twenty different amino acids: Glycine, alanine, valine, leucine, isoleucine, methionine, phenylalanine, tryptophan, proline, serine, threonine, cysteine, tyrosine, asparagine, glutamine, aspartic acid, glutamic acid, lysine, arginine and histidine
Hydrophilic ("water loving") amino acid side chains are either charged or polar. Both are attracted by water molecules. Histidine, Lysine, Glutamate, Aspartate, Arginine Hydrophobic: Alanine, Isoleucine, Leucine, Phenylalanine, Valine, Proline, Glycine, Methionine, Phenylalanine, Tryptophane, Cysteine. Less Hydrophobic: Tyrosine, Histidine, Serine, Threonine, Proline, Glycine, Alanine, Glutamine
Yes, tyrosine is polar. It contains a hydroxyl group (-OH) which makes it polar due to unequal sharing of electrons in the molecule. This allows tyrosine to form interactions with other polar molecules or groups.
It is non polar. In amino acids, "polar" or "nonpolar" refers specifically to the side chain; the molecule as a whole is definitely polar, but leucine's side chain is a hydrocarbon with no polar groups.
Yes serine is a polar amino acid as it has an hydroxyl group (OH-) attached to the r group.
The functional group of serine is a hydroxyl group (-OH) attached to its side chain. This hydroxyl group allows serine to participate in hydrogen bonding and chemical reactions, making it an important amino acid in protein structure and enzyme catalysis.
At pH 5.7, serine would have a positive charge. This is because the pKa of serine's side chain is around 9.21, so at pH below its pKa, the side chain will be protonated, resulting in a positive charge.
Wherever their associated triplet codons occur within the associated mRna's.
The codons ACU, CCA, and UCG correspond to the amino acids threonine, proline, and serine respectively. Therefore, the amino acid chain formed by these codons would be threonine-proline-serine.
The leucine side chain is nonpolar and hydrophobic, so it would most likely be found in the interior of the protein away from the water molecules. This helps to stabilize the protein's structure by minimizing its exposure to the aqueous environment.
compare chain surveying with modern technique such as total station?
No, critical mass does not depend on polarity. Critical mass is simply the amount of fissile material needed to sustain a nuclear chain reaction. Polarity, which is a property of molecules, does not play a role in determining critical mass.
Well, darling, serine is definitely a hydrophilic amino acid. It's got that polar side chain with a lovely little hydroxyl group that just can't get enough of water. So, if you're looking for a hydrophobic amino acid, you'll have to keep on searching because serine is all about that hydrophilic life.

The mRNA sequence that would produce the amino acid chain His-Ser-Arg would be 5'-CAU AGU CGU-3'. This sequence codes for the amino acids Histidine (His), Serine (Ser), and Arginine (Arg) through the genetic code.
