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.
Which term describes an amino acid normally found in the blood?
The term "free amino acid" describes an amino acid that is normally found in the blood.
What is the substrate of carboxypeptidase?
The substrate of carboxypeptidase is a peptide or protein molecule with a terminal amino acid that contains a free carboxyl group. Carboxypeptidase cleaves this terminal amino acid from the substrate by hydrolyzing the peptide bond.
What are the structural differences between the n and c terminus of a protein?
The N-terminus of a protein is where the amino acid chain starts, while the C-terminus is where it ends. The N-terminus has a free amino group, while the C-terminus has a free carboxyl group. These structural differences play a role in the function and stability of the protein.
What are the key differences between the n-terminus and c-terminus of a protein?
The N-terminus of a protein is the end where the amino acid chain starts, while the C-terminus is where it ends. The N-terminus typically has a free amino group, while the C-terminus has a free carboxyl group. These differences can affect the structure and function of the protein.

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'.

The N-terminus of a protein is where the amino acid chain starts, while the C-terminus is where it ends. The N-terminus has a free amino group, while the C-terminus has a free carboxyl group. These differences in chemical structure affect how proteins fold and function.
How you can isolate free amino acid from protein?
To isolate free amino acids from proteins, you can use techniques such as acid hydrolysis, enzymatic digestion, or heating in the presence of strong acids or bases. These methods break down the protein structure, releasing the amino acids in a free form. Following this, techniques like chromatography or precipitation can be used to separate and purify the free amino acids from the protein debris.
How dansylchloride react with secondary amino acid?
the aminoacid reacts as a standard nucleophile using nitrogen's free electron pair; the chloride is a better leaving group because of its lower basicity.
What is the rule of trna during translation?
The tRNA functions as a sort of taxi service for amino acids. Transfer RNA attaches to a specific amino acid in the cytoplasm and takes it to the ribosome, where it will pair its anticodon with the corresponding mRNA codon, and the amino acid on the tRNA molecule is added to the protein being produced. The tRNA then releases the amino acid and is free to pick up another of the same kind of amino acid, and take it to the ribosome.
What is basis nature amino acids?
As proteins are amino acids so all peptides and polypeptides are polymers of amino acids. There are 20 amino acids that are relevant to the make-up of mammalian proteins Several other amino acids are found in the body free or in combined states (i.e. not associated with peptides or proteins).
