A carboxyl group consists of a carbon double-bonded to an oxygen and also bonded to a -OH group. Compounds with carboxyl groups are called carboxylic acids or organic acids. The carboxyl group can act as an acid when by donating a proton (H+) to a solution and becoming ionized.
Similarly, it is asked, what forms a disulfide bond?
Disulfide bonds in proteins are formed between the thiol groups of cysteine residues by the process of oxidative folding. The other sulfur-containing amino acid, methionine, cannot form disulfide bonds. That is, the disulfide bond destabilizes the unfolded form of the protein by lowering its entropy.
Which functional group acts as a weak base?
Keyboard Shortcuts for using Flashcards:
|Alcohol||highly polar and may act as a weak acid O-H|
|carboxylic acid||acts as an acid -COOH|
|aldehyde||may be a structural isomer of a ketone C=O|
|thiol||forms disulfide bonds S-H|
