The amino (-NH2) group is stronger neucleophile than some other functional groups for example hydroxyl group. The electron lone pair is tightly held in oxygen whereas in nitrogen it is loosely held and is readily available to react. That is why functional groups containing nitrogen are acetylated much easily than those containg oxygen for example.
What else can I help you with?
True or False A peptide bond joins the amino group of one amino acid to the amino group of another amino acid?
False. A peptide bond joins the carboxyl group of one amino acid to the amino group of another amino acid.
Which amino acid has no free alpha amino group?
Proline is the amino acid that does not have a free alpha amino group in its side chain. This is because proline's side chain cyclizes back to the amino group, forming a unique structure that lacks a free alpha amino group.
What contains both a carboxyl group and an amino group?
An amino group and an R group
Identify a functional group always present in amino acids?
Two functional groups are found in all amino acids. These functional groups are the amino group (-NH2) and the carboxyl group (-COOH). The hydrogen atom of the carboxyl group can be broken off quite easily; this gives amino acids their acidic properties.
What amino acid has a methyl group as its R group?
Alanine is the amino acid with a methyl group as its R group.
Why is the carboxyl group not acetylated in aspirin preparation?
i ask you to answer it
Do amino acids amino have an amino group?
No,fatty acids don't have an amino group
What are the two main amino groups and how many of each is there?
The two main amino groups are the amino group (-NH2) and the carboxyl group (-COOH). In the context of amino acids, each amino acid contains one amino group and one carboxyl group, making a total of one amino group per amino acid. Therefore, for a standard amino acid, there is one amino group and one carboxyl group present.
True or False A peptide bond joins the amino group of one amino acid to the amino group of another amino acid?
False. A peptide bond joins the carboxyl group of one amino acid to the amino group of another amino acid.
What type of organic compound always includes a carboxyl group and an amino group?
An amino acid always has an amino group and a carboxyl group. The amine group of one amino acid is capable of forming a peptide bond with the carboxyl group of another amino acid.
Is the amino group acidic or basic?
The amino group is basic.
WHY IS CARBOXYL GROUP NOT ACETYLATED?
The carboxyl group (-COOH) is not acetylated because it is already a fully functionalized group that contains both a carbonyl (C=O) and a hydroxyl (–OH) component. Acetylation typically involves the addition of an acetyl group (–COCH3) to nucleophilic sites, and the hydroxyl group in a carboxylic acid is not a suitable site for acetylation due to its strong acidity and reactivity. Additionally, acetylation would convert the carboxyl group into an ester, which alters its chemical properties and functionality.
Is an amino group functional?
For forming a peptide bond, it is essential. There are a number of amino acids that have an amino group as an R-group, as well.
Why is the R group in amino acids?
The R group in an amino acid are what make that amino acid unique.
Which amino acid has no free alpha amino group?
Proline is the amino acid that does not have a free alpha amino group in its side chain. This is because proline's side chain cyclizes back to the amino group, forming a unique structure that lacks a free alpha amino group.
What group do amino acids always contain?
The amino acids are distinguished by the R groups which determines what amino acid it is.
When 2 amino acids link together what bond is formed?
When two amino acids link together, a peptide bond is formed. This bond is a covalent bond formed between the amino group of one amino acid and the carboxyl group of another amino acid. Peptide bonds are the building blocks of proteins.
