Why proline amino acid gives yellow colour in reaction with ninhydrin?
Yes. Within "The Chemical Reactions of Amino Acids / Reactions of Amino Groups" there are several examples - one of which is the ninhydrin reaction. A very widely applied reaction of the alpha amino group [that is the N in the peptide bond -CCN-CCN-], it is used to estimate the quantity of amino acids [in a sample] in very small amounts. All amino acids and polypeptides with a free alpha group react with ninhydrin and yield [or produce] an intensely purple colored product - except for Proline and Hydroxyproline {both in which the alpha amino group is termed to be 'substituted' - something to do with carbon rings} which "yield derivatives with a characteristic yellow color." See also 'Schiff's bases'.
What are amino acids that cannot be made by metabolism called?
Amino acids that cannot be made by metabolism are called essential amino acids. These amino acids must be obtained through diet.
What are some items that are made out of nitrogen?
ammonia(Nitrogen+hydrogen) nitric acid nitrogen dioxide nitrous oxide amino acids & proteins cyanides
What monomers make up protiens?
amino acid
What molecules form protiens when linked together with covalent bonds?
Amino acids are the molecules. Dipeptide bonds is the specific name for the covalent bonds.
Proteins are made up of monomers called?
The monomers of proteins are amino acids.

What repeating units make up a protein fatty acids peptide acids amino acids carboxylic acids?
They are the amino acids. They are the monomers
Proteins are formed of building blocks called?
Amino acids held together by peptide bonds.
Monomer of proteins?
Amino acids.
What is the basis of the test for cellulose with Shultz stain?
Proteins get denatured when acid is added and this forms a white coagulum which is slightly yellow in colour because of nitro- derivatives of proteins given by aromatic amino acids.Read more: What_is_the_basis_of_Heller's_test_in_biochemistryget denatured when acid is added and this forms a white coagulum which is slightly yellow in colour because of nitro- derivatives of proteins given by aromatic amino acids.
How many acids are their?
amino acids?? 20 amino acids
What are amino acids that cannot be made by metabolism called?
Amino acids that cannot be made by metabolism are called essential amino acids. These amino acids must be obtained through diet.
Proteins are polymers formed from?
Proteins are polymers made up of amino acids.
What molecule links together to form proteins?
Amino acids
What are protiens digested into?
They are digested into your mom
