Peptide Bond and its formation (amino acids)- JEE||NEET||CBSE (IITian Faculty)(Hindi)
 
05:14
"IITian Faculty" explains the above concept in entertaining and conceptual manner.
Peptide bond
 
06:16
This lecture explains about peptide bond formation and about the ramachandran plot and protein structure analysis of the peptide bonds. A peptide bond is a chemical bond shaped between two molecules when the carboxyl crew of 1 molecule reacts with the amino team of the opposite molecule, releasing a molecule of water (H2O). This can be a dehydration synthesis reaction (often referred to as a condensation reaction), and most often happens between amino acids. The ensuing CO-NH bond is known as a peptide bond, and the resulting molecule is an amide. The four-atom functional group -C(=O)NH- is referred to as an amide team or (in the context of proteins) a peptide crew. Polypeptides and proteins are chains of amino acids held together via peptide bonds, as is the backbone of PNA.

Molecular Basis of Inheritance:TRANSLATION: Arrangement of amino acids in a linear, specific sequence and formation of polypeptide chain according to the specific sequence of information written on m-RNA is called translation changing the code language on m-RNA into the language of amino acids. Translation occurs in the cytoplasm. The primary requirements for translation process are ribosomes, m-RNA, t-RNA, amino acids, enzymes, ATP, GTP and specific activators. The process of translation involves,1Activation of amino acids - its transfer to t-RNA. 2. Initiation of polypeptide chain. 3Elongation of polypeptide chain and. 4 Chain termination. 5Activation of amino acids and its transfer to t-RNA:Amino acids are activated by ATP in the presence of an enzyme known as amino acyl synthetase and linked to their cognate t-RNA, a process called as charging of t-RNA or amino acylation of t-RNA. As a result amino acyl t-RNA is formed which moves towards ribosomes.AA amino acid + ATP + Enzyme amino acyl synthetase→ AA + AMP + Enzyme Complex + PP pyrophosphateAA-AMP-Enzyme complex + t-RNA → AA-t-RNA complex + AMP + enzyme Amino acyl t-RNA. 2. Initiation of polypeptide chain:AUG is the initiation codon of m-RNA. It codes for Methionine. Formyl group is attached to free amino group of methionine. The t-RNA bringing formyl methione is called f.met. t-RNA and it acts as initiator.As the anticodons of t-RNA are complementary to the codons of m-RNA they can develop loose hydrogen bonds with codons of m-RNA. Ribosomes have two sites for t-RNA: 1Aminoacyl or acceptor site or "A"site 2Peptidyle site or "P" site in the larger sub- unit. Aminoacyl t-RNA first binds to A-site of ribosomes & move to P-site while initiator t-RNA first binds to p-site.The initiator amino acyl t-RNA in the presence of m-RNA combines with sub units of ribsomes. This process requires energy.3.Elongation of polypeptide chain: Chain elongation takes place by the establishment of peptide bonds between the amino acids as the ribosomes move along m-RNA one codon at a time in 51 →31 direction. Depending on the second codon of m-RNA, the t-RNA with anticodon complementary to the codon of m-RNA forms a complex with the corresponding activated amino acid and moves to the ribosomes and binds at the 'A' site. This is facilitated by elongation factor & energy in the form of GTP.Formyl methionine in P-site establishes a peptide bond with the second amino acid at 'A' site. Polypeptide chain grows in C→ N direction.carboxyl group of first amino acid and amino group of second amino acid). Peptide bond is catalysed by the enzyme peptidyl transferase.After the bond formation ribosomes move to the next codon of m-RNA. This movement of ribosomes relative to m-RNA resulting in the shift of peptidyl t-RNA from 'A' site to 'P' site is called translocation.Translocation requires translocase & GTP. Therefore aminoacyl t-RNA enters 'A' site and moves to 'P'site after developing peptide bond. 1 Chain termination: When the terminating codons UAA, UAG or UGA present in m-RNA, it indicates the end of polypeptide synthesis. They do not code for any amino acid and hence no amino acid enters 'A' site and thus they act as stop signals. At the end, a relative factor binds to the stop codon, terminating translation and releasing the complete polypeptide from the ribosome.

A peptide bond (amide bond) is a covalent chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, causing the release of a molecule of water (H2O), hence the process is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids. The resulting C(O)NH bond is called a peptide bond, and the resulting molecule is an amide. The four-atom functional group -C(=O)NH- is called a peptide link. Polypeptides and proteins are chains of amino acids held together by peptide bonds, as is the backbone of PNA. A peptide bond can be broken by hydrolysis (the adding of water). In the presence of water they will break down and release 8--16 kilojoule/mol (2--4 kcal/mol) [1] of free energy. This process is extremely slow (up to 1000 years). In living organisms, the process is facilitated by enzymes. Living organisms also employ enzymes to form peptide bonds; this process requires free energy. The wavelength of absorbance for a peptide bond is 190--230 nm[2] (which makes it particularly susceptible to UV radiation). Source of the article published in description is Wikipedia.

Amino Acids (Part 5 of 5) - Peptides, Polypeptides, and Peptide Bonds
 
20:11
Moof's Medical Biochemistry Video Course: http://moof-university.thinkific.com/courses/medical-biochemistry-for-usmle-step-1-exam For Related Practice Problems with Worked Video Solutions on Amino Acids, visit courses.moofuniversity.com. What are peptides and polypeptides and peptide bonds? Find out in this video! It is commonly mentioned that amino acids are the building blocks or monomers of proteins, which are, of course, polymers. Specifically, amino acids link between the alpha carboxylic acid group of the first amino acid and the alpha amino group of the next amino acid via dehydration synthesis, creating an amide bond that is specifically called a peptide bond. This covalent bond is fairly rigid and planar in structure due to its partial double bond character due to the resonating lone pair of electrons on the amide nitrogen. Rotation about this bond is restricted due to its planar nature. When two amino acids link via a peptide bond, it's called a dipeptide -- because two amino acids make up that structure. A tripeptide is three amino acids linked by peptide bonds. A peptide is the term associated with a short segment of a few amino acids connected by peptide bonds. A polypeptide is simply a long chain amino acids connected by peptide bonds. When, then, do we have a protein? Are peptides proteins? Are polypeptides proteins? For the most part, a protein is a polypeptide that has folded into a particular structure that has some role or function -- be it a structural role or a catalytic/enzymatic role. So, I often say that a protein is a folded and functional polypeptide. So, all proteins are polypeptides. However, not all polypeptides are proteins; they need to fold into a functional form to be considered a protein.

Peptide
 
01:06
The bond formed between two amino acids by the elimination of a water molecule is called a peptide linkage or bond. The product formed by linking amino acid molecules through peptide linkages, -- CO -- NH --, is called a peptide. Peptides are further designated as di, tri, tetra or penta peptides accordingly as they contain two, three, four or five amino acid molecules, same or different, joined together. Peptides are short polymers of amino acid monomers linked by peptide bonds, the covalent chemical bonds formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule. Peptides are distinguished from proteins on the basis of size, typically containing fewer than 50 monomer units. The shortest peptides are dipeptides, consisting of two amino acids joined by a single peptide bond. There are also tripeptides, tetrapeptides, etc. Amino acids which have been incorporated into a peptide are termed "residues"; every peptide has a N-terminus and C-terminus residue on the ends of the peptide (except for cyclic peptides). A polypeptide is a long, continuous, and unbranched peptide. Proteins consist of one or more polypeptides arranged in a biologically functional way and are often bound to cofactors, or other proteins. The size boundaries that distinguish peptides, polypeptides, and proteins are arbitrary. Long peptides such as amyloid beta can be considered proteins, whereas small proteins such as insulin can be considered peptides. www.edufine.net

Peptide bond formation between two amino acids - analogy to amide formation
 
15:26
The chemistry here is identical to amide formation (condensation of a carboxylic acids with an amine). In this case, the amino- and carboxylic acid functional groups are coming from 2 different amino acids. The result is a "peptide bond" between the two amino acid reactants. When the reaction occurs in a ribosome, a transfer RNA is released instead of the water, but the chemistry is identical.
