What else can I help you with?
Peptide bonds form when the amine group of one amino acid combines with the organic acid group of another amino acid?
A peptide bond. Although some amino acids can form other bonds depending on their R groups (cysteine can form a disulfide bond with another cysteine... forming a cystine).
Would cysteine test positive in a biuret test?
Yes, cysteine would test positive in a biuret test. This is because cysteine, like other amino acids, contains peptide bonds that react with the copper ions in the biuret reagent to form a purple color complex.
What food contain peptide most?
milk
Why bond between two amino acid is called dipeptide?
Say you're looking at cysteine and serine.Two possible combinations are: cysteine's NH2 group bonds to serine's COOH group OR cysteine's COOH group bonds to serine's NH2 group. These two different combinations of the order of the molecules makes them totally different. They are called isomers. :)
What is cysteine milk?
cysteine is an amino acid which exists inside milk(also found in other places). it is important for its di-sulphide (s-s) bonds which are activated through heating (like pasteurization). it is an essential amino acid which the body needs to receive constantly, but meat is a more common source of cysteine for the body.
What is the difference between a peptide and a peptone?
The difference between a peptide and peptone is not complicated. A peptone is derived from animal milk and peptides are not.
What are some examples of dipeptides?
Glycylglycine, alanylalanine, and cysteine-glycine are examples of dipeptides. Dipeptides are molecules made up of two amino acids linked together by a peptide bond.
How a second amino acid would bond to cysteine in forming the primary strusture of a protein?
A condensation reaction between the acid group of one amino acid and the amino group of another forms a covalent bond between two amino acids. A water molecule is also produced. A new bond formed is called a peptide bond.
Is cysteine a polar or nonpolar molecule?
Cysteine is a polar molecule.
Is cysteine considered hydrophobic or hydrophilic?
Cysteine is considered hydrophobic.
What is the chemical make up of cysteine?
The chemical formula of cysteine is C3H7NO2S.
Is cysteine a nonpolar amino acid?
No, cysteine is a polar amino acid.
