a polypeptide is a a sequence of amino acids covalently bonded together by a peptide bond. The peptide bond is formed when two adjacent amino acids come together by way of condensation reaction (loss of a water molecule) to form the covalent bond between them.
Amino acids and polypeptides are the building blocks of protein.
Amino acids are the basic unit of proteins. Amino acids linked together by a peptide bond forms a chain of amino acids called a polypeptide. When the amino acids from different parts of the chain interact with each other and form hydrogen bonds, the polypeptide chain takes on a unique shape, forming a protein.
One you just made up, because with a Ph.D. in chemistry I've never heard the term "polypeptide bond".
A "peptide bond" is one between a nitrogen and a carbonyl (it's formed when a carboxylic acid reacts with an amine, and is sometimes also called an "amide" bond).
A polypeptide is a chain of peptide bonds. manyy polypeptide chains are what make up an amino acid. I hope that helps:)
Polypeptides are chains of amino acids - joined together with peptide bonds (hence the name poly, meaning 'many', peptides).
Short lengths of amino-acid strands are polypeptides - see also The Peptide Bond.
covalent bond
may be hydrogen bonding
A peptide bond is a polypeptide bond. This is just a bond between two amino acids in a long chain.
Biuret solution turns a shade of purple if proteins are present. Specifically, it turns a shade of purple if peptide bonds are present. A peptide bond is the bond formed between amino acids.
The biuret reaction is based on the reduction of Cu2+ to Cu+ which then complexes with the nitrogen atoms on the peptide bonds. This reactionis carried out at high pH and gives a violet colour. It is the amide bond (common to all proteins) which is resposible for the colour.
Covalent Bond occurs between two non metals.
Iodine and Carbon form a covalent bond. Moreover, this bond is nonpolar. Cheers, Caroline
a hydrogen bond
An amino acid links with another amino acid through a condensation reaction to form a peptide bond. This process continues until a polypeptide chain is formed.
peptide bond
Amino acids do not have hydrogen bonds. They only have an alpha corbon atom connected to 4 groups namely: Hydrogen A variable R group An amide group A carboxyl group
Peptide bond is the bond formed between amino acids. Glycosidic bond is the bond formed between simple sugars Peptide bond is the bond formed between amino acids. Glycosidic bond is the bond formed between simple sugars
Amino acids bond by peptide bonds to make a polypeptide. Proteins are made of polypeptides.
a peptide bond
Basically, proteins are long chains of amino acids, which are linked together through a chemical bond known as a peptide bond. They can be hundreds of amino acids in length. Peptides, which qualify as proteins, are just shorter chains of amino acids, generally between 2 and 100 amino acids. In biochemistry, amino acids are also referred to as residues; thus a 5 residue polypeptide is just a 5 amino acid long peptide, linked together with a peptide bond between each residue.
When monosaccharides are joined together by dehydration synthesis then it is called glycosidic linkage, it is a covalent bond. When lipids are being bonded together the bond is called an ester bond. When amino acids are joining together to form a polypeptide then the bonds are called peptide bonds.
A polypeptide chain is made up amino acids that form from a peptide bond. The polypeptide chain makes up a protein; therefore, the type of protein is contingent on the number of chains present.
the bond connecting two aminoacid is peptide bond
The covalent bonds between amino acids are called peptide bonds. It is a bond between the carboxyl group of one amino acid and the amino group of another amino acid. Amino acids are bonded through condensation reactions, which produces a water molecule.
A bond formed during translation is a peptide bond. It forms between the amino acids in the growing polypeptide chain being synthesized by the ribosome. The formation of the peptide bond occurs through a condensation reaction between the amino group of one amino acid and the carboxyl group of another amino acid.
