what are peptide bonds and where are they found?

Answer 1

We have many amino acids we can make the required amino acids are ones we cannot make. Amino acids give up parts of themselves to hook together to make a chain which forms a polypeptide then eventually a protein when it is larger.

Peptide bond
From Wikipedia, the free encyclopedia
Jump to: navigation, search
A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids. The resulting CO-NH bond is called a peptide bond, and the resulting molecule is an amide. The four-atom functional group -C(=O)NH- is called an amide group or (in the context of proteins) a peptide group. Polypeptides and proteins are chains of amino acids held together by peptide bonds, as is the backbone of PNA.

The amino acids are linked linearly through peptide bonds. These bonds are formed via a dehydration synthesis reaction between the carboxy group of the first amino acid with the amino group of the second amino acid.

A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids. The resulting CO-NH bond is called a peptide bond, and the resulting molecule is an amide. The four-atom functional group -C(=O)NH- is called an amide group or (in the context of proteins) a peptide group. 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 amide hydrolysis (the adding of water). The peptide bonds in proteins are metastable, meaning that in the presence of water they will break spontaneously, releasing about 10 kJ/mol of free energy, but this process is extremely slow. 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 190-230nm.

Answer 4

Since each protein molecule consists of a long chain of amino acid residues, linked to each other by peptide bonds, the hydrolytic cleavage of all peptide bonds is a prerequisite for the quantitative determination of the amino acid residues.

Answer 5

well peptide bonds are the bonds formed btn. the NH2 & CONH2 they are found in the amino acids which are the units of proteins

Answer 6

Made of amino acids. Found in living tissue.

Answer 7

These are found in proteins, and are what hold all structure in the body together.

Answer 8

in your body - they are built from amino acids
