Do all proteins contain alpha helixes and beta pleated sheets?
Not all proteins contain alpha helices and beta pleated sheets. These structures are specific types of secondary protein structures typically found in many proteins, but some proteins may lack these features entirely. The presence of alpha helices and beta sheets depends on the protein's amino acid sequence and overall folding. Some proteins may adopt entirely different conformations or structures, such as random coils or unique motifs.
Do amino acids contain alpha and beta pleated sheet in their secondary structure?
Yes, they do. Side group hydrogen bonding.
Proteins can be shaped as an alpha helix a beta pleated sheet or a glob?
Proteins can adopt various structural forms, including alpha helices, beta pleated sheets, and globular shapes, which are determined by their amino acid sequences and interactions. Alpha helices are coiled structures stabilized by hydrogen bonds, while beta pleated sheets consist of adjacent strands linked through hydrogen bonds, creating a sheet-like formation. Globular proteins, on the other hand, are more compact and spherical, often functioning as enzymes or hormones. These diverse shapes are crucial for the protein's specific functions in biological processes.
The alpha helix and beta pleated sheet represent which level of protein structure?
The alpha helix and beta pleated sheet represent the secondary structure of proteins. Both structures are formed by the interaction of amino acids within the polypeptide chain through hydrogen bonding.
Does polypeptide forms a pleated sheet or a helix as its tertiary structure?
Polypeptides can form both pleated sheets and helices, but these structures are typically associated with secondary rather than tertiary structure. In secondary structure, alpha helices and beta pleated sheets arise from hydrogen bonding between the backbone atoms of the polypeptide chain. Tertiary structure refers to the overall 3D shape of a polypeptide, which is determined by various interactions among side chains, including hydrophobic interactions, ionic bonds, and disulfide bridges.

What does Alpha helix and beta pleated sheets make up?
together they make a secondary protein structure
Is ptylin an alpha amylase or beta amylase?
Ptyalin is an alpha-amylase. It is the alpha-amylase found in saliva
Which type of interaction stabilizes the alpha helix and the beta pleated sheets of a protein?
Hydrogen bonding is the primary interaction that stabilizes the alpha helix and beta pleated sheets of a protein. In the case of alpha helices, hydrogen bonds form between the carbonyl oxygen of one amino acid residue and the amide hydrogen of another residue in the chain. In beta sheets, hydrogen bonds form between adjacent strands of the sheet.
Is it aminoaacids that are the secondary structure of alpha helix and beta pleated?
The secondary structures of alpha helix and beta pleated sheets are formed by hydrogen bonding between amino acids in a protein chain. In an alpha helix, the hydrogen bonding occurs between amino acids in the same chain, leading to a helical structure. In beta pleated sheets, hydrogen bonding occurs between amino acids in different segments of the protein chain, creating a sheet-like structure.
Alpha helices and beta-pleated sheets are examples of .?
protein secondary structures, which are common motifs found in protein folding. Alpha helices are formed by a right-handed coil of amino acids stabilized by hydrogen bonding, while beta-pleated sheets are formed by hydrogen bonding between adjacent strands of amino acids running in parallel or antiparallel orientation.
What are the two most common secondary structures in a protein?
The two types of tertiary protein structures: globular and fibrous proteins. Globular proteins act as enzymes that catalyze chemical reactions in organisms. Fibrous proteins like collagen play structural role.
Do amino acids contain alpha and beta pleated sheet in their secondary structure?
Yes, they do. Side group hydrogen bonding.
What type of compound and bond is hydrolized by the alpha amylase?
Alpha bonds are hydrolised by alpha amylase. The alpha amylase is the sole form of amylase found in all mammals.
How does saliva alpha amylase work?
Amylase is an enzyme that induces hydrolysis of starches, breaking them down into sugar. Saliva alpha amylase is simply a type of amylase.

What are the key differences between alpha amylase and beta amylase in terms of their functions and roles in starch degradation?
Alpha amylase and beta amylase are enzymes that break down starch, but they have different functions. Alpha amylase breaks down starch into maltose and other sugars, while beta amylase specifically breaks down starch into maltose. Alpha amylase works on the interior of starch molecules, while beta amylase acts on the ends of starch molecules. Overall, alpha amylase is more versatile in breaking down different types of starch, while beta amylase has a more specific role in starch degradation.
