A protein's structure is determined by:
- the amino acid sequences of its polypeptide chains;
- hydrogen bonds between amino acids in polypeptides;
- other bonds (e.g. hydrophobic interactions, disulphide bridges) between side chains in the polypeptides; and
- the arrangement of polypeptides (in a protein that contains more than one polypeptide)
Scientists have mapped the structures of several proteins; however, scientists are still unsure as to how proteins actually form their final structures.
The function of a protein is directly related to its structure. For example, a protein that fights a certain bacteria might have a shape that allows it to bind to the bacteria and then destroy it.
What else can I help you with?
what are polymers made of amino acids called?
Polymers made of amino acids are called polypeptides or proteins. Amino acids are the building blocks of proteins, and they are linked together through peptide bonds to form long chains known as polypeptides. These polypeptides can then fold into specific shapes to carry out various functions in the body.
Why is it more difficult to analyze proteins than DNA?
Proteins are much more structurally and functionally complex than DNA, as they can fold into diverse three-dimensional shapes and exhibit a wide range of functions. Additionally, proteins have post-translational modifications that further increase their complexity. Analyzing proteins often requires specialized techniques and expertise, making it more challenging than analyzing DNA.
Different kinds of solids have BLANK of different shapes?
Different kinds of solids have surfaces of different shapes.
How do amino acids contribute to the formation of proteins?
Amino acids are the building blocks of proteins. They link together in a specific sequence to form long chains, which then fold into complex shapes to create proteins. This process is essential for the structure and function of proteins in the body.
What does the VSEPR theory describes?
VSEPR is valence spin electron pair repulsion, and helps in describing the electron domain geometry and the molecular geometry of a substance.
What are the different shapes and functions of different proteins determined by?
The R groups of the amino acids they contain.
What does a protein's shape determine, considering that proteins vary in shape?
A protein's shape determines its function, as different shapes allow proteins to interact with specific molecules in the body. Proteins with different shapes perform different roles in the body, such as enzymes facilitating chemical reactions or antibodies recognizing and binding to foreign substances.
Why are shapes and sizes of cell different?
Cells are different shapes and sizes because they have different functions. The functions dictate the shapes and sizes.
Why is there infinite variety possible in proteins?
Proteins are made up of 20 different amino acids, which can be arranged in numerous ways to form a vast array of protein structures. Additionally, proteins can fold into various shapes and structures due to their flexibility, allowing for diverse functions and interactions with other molecules. This variability in amino acid sequence and protein structure contributes to the infinite variety of proteins that can be produced in living organisms.
How do plant cells have different shapes?
To perform different functions plant cells assume different shapes
What determines the shapes of different types of Cells?
Cell shapes are Genetically Determined by and through Biochemistry.
Differences in R-groups give different proteins different what?
shapes
Why are nerve cell and muscle cell different shapes?
Their different shapes help them to perform their various functions (jobs)
Is this true or false proteins can be used interchangeably in the body because they have similar structures?
False. Proteins have very specific shapes and functions and cannot be used interchangeably.
What part of the cell receives proteins from the ribosomes and modifies and shapes the into functions?
Rough Endoplasmic reticulum (Rough ER)
Why are pores in a cell membrane different sizes?
The size of the membrane pores depend on the proteins constituting the pore, thus different proteins may cause different pore sizes. So in most cases, yes, the "pores" will most likely be of different sizes.
The different shapes and functions of proteins are determined by?
The different shapes and functions of proteins are determined by their amino acid sequence, which dictates how they fold into complex three-dimensional structures. These structures are further influenced by environmental factors such as pH, temperature, and the presence of other molecules. The specific shape of a protein is crucial for it to carry out its biological function effectively.
