Question

End products of protein hydrolysis are
A. Mixture of amino acids
B. Sugars
C. Peptides
D. 25 amino acids

Answer 1

Hint: Proteins are heteropolymers containing strands of amino acids.
Structure of molecules means the different things in different contexts.
In organic chemistry, the structure invariably refers to molecular formulae.
The protein structure is explained at four different levels.

Complete answer:
Proteins are essential nutrients for the human body.
They are one of the elementary units of body tissue and can also serve as a fuel source.
Protein provides us energy because it serves as a fuel source.
Proteins are polymer chains made of amino acids that are linked together by peptide bonds.
During human digestion, proteins are broken down in the stomach to smaller polypeptide chains via HCL and protease actions.
There are basically nine essential amino acids which humans must obtain from their diet in order to prevent protein energy malnutrition and resulting death.
They are phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine and histidine.
Hydrolysis: hydrolysis means chemical breakdown of substance due to the presence of water.
When digestive proteolytic enzymes act upon the protein in the gut the peptide bonds get hydrolyzed and a mixture of amino acids is obtained.

Hence, The correct answer is option (A).

Note: Amino acids are organic compounds that combine to form proteins.
Amino acids and proteins are the elementary units of life.
When proteins are digested or broken down we obtain the mixture of amino acids.
The human body uses amino acids to make proteins to help the body in Breaking down food.
The key elements are carbon, oxygen, nitrogen and hydrogen.
