Question

As a macronutrient, proteins are unique in that they contain which atom ? ____________

There are 20 common amino acids. How many of these are essential amino acids? ______________________

Amino acids are joined together by peptide bonds. What reaction takes place to join amino acids together ? ______________________________

Number of amino acids complete the following table.

Peptide

Dipeptide

Tripeptide

Polypeptide

Provide a definition for deamination?

Provide a definition for transamination?

Excess nitrogen needs to be excreted from our bodies. In the form of ammonia, nitrogen is toxic, so our body combines ammonia with carbon dioxide to make urea which can be excreted through the kidneys. What impact does this have on our fluid requirements?

The instructions for making a protein are the __________________________

The template for the instructions is the _______________________________

The amino acid carrier is the ________________________

_____________________ ensures that amino acids are placed in the correct positions

The amino acids are bonded together by the _________________________________

Answer 1

1. Proteins are biomolecules made up of amino acids linked together by peptide bonds. Amino acids constitute a chiral carbon bonded to a carboxylic side chain (C terminal end) and an amino terminus (N terminus). The peptide bond is formed bbetween this CO-NH group.

2. Amino acids that cannot be made by the body are known as essential amino acids. As a result, they must come from food. The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

3. Each amino acid is attached to another amino acid by a peptide bond (covalent bond). When two amino acids are covalently attached by a peptide bond, the carboxyl group of one amino acid and the amino group of the incoming amino acid combine and release a molecule of water, so peptide bond formation is an example of a dehydration reaction.

4. peptide-1, dipeptide-2, tripeptide-3, polypeptide- >8

5. Deamination is the removaal of oxygen from an amino acid protein. In our body it is generally done by the enzyme deaminase.

In transamination, amino group is transferred to a correspnding Keto acid to get a new amino acid.

6. AS urea is excreted, our need for fluid intake increase as water is needed to dilute the urea and also play other key symbolic roles in the body's metabolism.

7. Instructions for making a protein- mRNA. The ribosome protein synthsising machinery read the mRNA and produce proteins. Template for instruction is in bengsl movies. Amino acud are brought by the tRNA.

8. Growth and Maintenance.

Causes Biochemical Reactions.

Acts as a Messenge

Provides Structure.

Balances Fluids.

Bolsters Immune Health. ...

Transports and Stores Nutrients.

9. HIgh protein-- dairy producs, eggs, almonds, oats etc.

10. For vegans, thy can find protein in tofu, sietan, yeast etc.
