The proline side chain forms a closed ring with it's closest carbonyl of the polypeptide backbone. - this is a debated term for referring to proline and hydroxyproline, and is a rather erroneous and antiquated usage.
More accurately, proline is an alpha amino acid that has a secondary amino group, rather than the primary amino group found in the other 19 natural amino acids. A secondary amino group is one in which the nitrogen is single bonded to a hydrogen and two sp3-hybridized carbons, whereas a primary amino group is one in which the nitrogen is single bonded to two hydrogens and one sp3-hybridized carbon.
An imino acid is a compound that has an imino group and a carboxylic acid group. An imino group is when nitrogen is double bonded to a carbon atom and single bonded to either a hydrogen atom or an sp3-hybridized carbon atom.
What else can I help you with?
Is proline considered a hydrophobic amino acid?
Yes, proline is considered a hydrophobic amino acid due to its nonpolar nature and tendency to repel water molecules.
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.
Which three codons would code for a different amino acid sequence from that coded for by the mrna base sequence agu uca cca?
AGU and UCA both code for the amino acid serine - so do the codons AGC, UCU, UCC and UCG. CCA codes for proline - so do CCU, CCC and CCG. Therefore any codons which do not code for the sequence serine-serine-proline will be different. For example: UUC-GCU-AAU will code for a different amino acid sequence
Interpret the genetic code to determine the amino acid coded for by the condon ccu?
The link below includes a table of codons and their respective amino acids. You can use this to determine the amino acid coded by any three nucleic acid bases. Read down, then across, then find the one you want from that block of four. In the case of CCU, the amino acid is proline.
Which amino acid chain will be formed by the codons shown below ACU CCA UCG?
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.
Which of the amino acids is actually an imino acid?
Proline is considered an imino acid because its side chain forms a cyclic structure that includes a nitrogen atom, leading to the name "imino acid." This unique structure restricts proline's conformational flexibility and makes it a key component in protein structures like collagen.
What is the example of an imino acid?
Alpha-imino-glutaric acid. The imino stands for a C=N double bond.
What amino acid is technically not an amino acid?
proline is not an amino acid it is an imino acid
What the possible codons for the amino acid proline?
proline!
What is the monomer of a protein please help can't find the answer a simple guess is fine too Anything helps?
Aminoacids (or imino in the case of proline.)
Which amino acid is represented by the codon UUU?
The amino acid Proline. In the Codon Dictionary, Proline is the best example of a "wobble base". Each codon that begins with CC- [CCU, CCC, CCA, & CCG] codes for Proline.
Is proline considered a hydrophobic amino acid?
Yes, proline is considered a hydrophobic amino acid due to its nonpolar nature and tendency to repel water molecules.
Is there any amino acid having secondary amino group in its structure?
The amino acid proline is the only amino acid that has a secondary amine functional group. This is because proline is a cyclic amino acid that links the 3-carbon R-group back to the amine group, resulting in a secondary amine.
Where can we find proline?
Proline is found in high-protein foods such as meat, dairy products, and eggs. It is also present in certain plant-based sources like soy products, avocado, and nuts. Additionally, proline can be found in dietary supplements or protein powders.
What amino acid residues are found in abundance in casein?
If not mistaken, it is proline.
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.
Which amino acid has its alpha nitrogen in a ring?
Proline has an alpha nitrogen in a ring.
