The sequence of amino acids determines each protein's unique 3-dimensional structure and its specific function. Amino acids are coded by combinations of three DNA building blocks (nucleotides), determined by the sequence of genes.

What is the key function of protein?
Protein has many roles in your body. It helps repair and build your body's tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance.
What is the most important thing about a protein that determines its function?
The shape of a protein is critical to its function because it determines whether the protein can interact with other molecules.
What are the 3 main functions of protein?
Explanation: catalysing metabolic reactions, DNA replication, responding to stimuli, and transporting molecules from one location to another. Many hormones are protein in nature; hormones control growth and metabolic activities of the body.
What gives proteins its unique properties?
A peptide bond. ... Attached to this repetitive chain are those portions of the amino acids that are not involved in making a peptide bond and which give each amino acid its unique properties: the 20 different amino acid side chains (Figure 3-2).
Why is a protein's conformation important?
Protein conformation is of paramount importance in understanding biomolecular interactions. ... For protein like haemoglobin that shows allosteric behaviour, the binding of small molecules at a region of the protein affects its binding affinity with other molecules at a distant region.
What makes different kinds of proteins unique?
The primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique three-dimensional shape.
Which part of an amino acid is unique?
Explanation: There is one certain part of the structure of an amino acid that define it. It is called the R part. All amino acids are the same except this part.
What are the 4 main elements making up proteins?
Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON). Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P). The body also needs trace amounts of other elements such as calcium, potassium, and sulfur for proper functioning of muscles, nerves, etc.
What is the key difference between carbohydrates and proteins?
Carbohydrates are used for energy (glucose). Fats are used for energy after they are broken into fatty acids. Protein can also be used for energy, but the first job is to help with making hormones, muscle, and other proteins.
How is a protein's shape related to its function?
The three-dimensional shape of a protein determines its function. This is because proteins form attachments and interact with many other molecules and structures inside organisms. The shape of a protein determines what it can interact with, just like the shape of a key determines which locks it can operate.
What makes amino acids unique from one another?
The side groups are what make each amino acid different from the others. ... These names refer to the way the side groups, sometimes called "R" groups, interact with the environment. Polar amino acids like to adjust themselves in a certain direction. Non-polar amino acids don't really care what's going on around them.
