What is an helical fold?
A helical fold is a structural motif in proteins where a segment of the polypeptide chain adopts a helical conformation different from the typical alpha-helix or beta-sheet structures. Helical folds are often involved in protein-protein interactions or in stabilizing protein structures.
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.
Proteins are composed of which of these subunits?
Proteins are composed of amino acids, which are the building blocks of proteins. Amino acids are linked together through peptide bonds to form polypeptide chains, which then fold into complex three-dimensional structures to create functional proteins.
What structures link together to form proteins?
Amino acids link together through peptide bonds to form proteins. Proteins are made up of long chains of amino acids that fold into complex three-dimensional structures based on the sequence of amino acids. Proteins are essential for many biological processes in the body.
What is the role of secondary protein structures in determining the overall function of a protein?
Secondary protein structures, such as alpha helices and beta sheets, play a crucial role in determining the overall function of a protein. These structures help proteins fold into specific shapes, which are essential for their function. The arrangement of these structures can affect how proteins interact with other molecules and carry out their biological roles.
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.
What proteins help new proteins fold into their normal shape?
chaperon protiens
Cells build their proteins from different kinds of amino acids?
Yes, cells use 20 different amino acids to build proteins. These amino acids are linked together in specific sequences to form chains, which then fold into various protein structures based on their unique properties. The specific sequence and arrangement of amino acids determine the function and properties of each protein.
Do large vacuoles fold proteins?
yup
What different foods represent the different structures of organelles?
Water, proteins, lipids, carbohydrates, salts, ions and vitamins.
What best describes the structure of the molecules that made up of protein?
Proteins are made up of long chains of amino acids linked together by peptide bonds. These chains fold into complex three-dimensional structures that are crucial for their function. The primary structure is the specific sequence of amino acids, while the secondary, tertiary, and quaternary structures refer to the different levels of folding and organization that give proteins their unique shapes and functions.
When amino acids bond together what are formed?
When amino acids bond together, they form peptides or proteins. Amino acids are joined by peptide bonds to create chains of varying lengths, which then fold into complex protein structures. This process is essential for the synthesis of proteins in living organisms.
