Concept explainers
Interpretation:
Amino acid that is hydrophilic has to be identified and explained.
Concept introduction:
Many amino acids are linked together through amide bonds to form a biologically large molecule known to be proteins.
Amino acid had both amino functional group and carboxyl functional group in a molecule.
Amino functional group is
The amino acids that are neutral are further classified into polar and non-polar.
The side chain are classified into hydrophobic (water hating) and hydrophilic (water loving).
Hydrophilic (water-loving):
The compound has the polar group such as hydroxyl group (
Hydrophobic (water-fearing):
The compound has non polar group such as alkyl chain and benzene ring is called as hydrophilic.

- Why is it important to specify the three-dimensional structure of amino acids?arrow_forwardOver time, the glutamine residues of polypeptides are susceptible to deamidation, a reaction in which the amide group is replaced by a carboxylate group. What amino acid is produced when glutamine is deamidated?arrow_forwardwhich two amino acid have two chiral center? I know Isoleucine contain two chiral center,how about another AA?arrow_forward
- What triggers a dehydration reaction between two amino acids, assuming they're perfectly aligned with a carboxyl group of one bordering the amine group of the other?arrow_forwardWhat chemical groups characterize a hydrophobic amino acid? A hydrophilic amino acid?arrow_forwardWhat initiates a dehydration process between two amino acids, provided that their carboxyl groups are precisely aligned with the amine groups of the other?arrow_forward
- Why do amino acids, when dissolved in water, become zwitterions?arrow_forwardAn amino acids unique property arises through which component? How does this same component contribute to the overall chemical nature of the protein?arrow_forwardIs it possible to form cyclic peptides without bonds between side chains of the component amino acids?arrow_forward
- The common naturally occurring form of cysteine has a chirality center that is named (R), however; (a) What is the relationship between (R)-cysteine and (S)-alanine? (b) Do they have the opposite three-dimensional configuration (as the names might suggest) or the same configuration? (c) Is (R)-cysteine a D-amino acid or an L-amino acid?arrow_forwardWhy is a string of bound amino acids called a polypeptide?arrow_forwardGiven this short polypeptide: Met-Ala-Gly-Ser A) Which is the amino terminal amino acid? B) How many amino acids are in this polypeptide? C) How many peptide bonds are in this polypeptide? D) Which amino acid has the smallest side chain? E) Which amino acid contains sulfur?arrow_forward
