The secondary structure that can take on two forms is the alpha helix and beta sheet, both of which are common in proteins. The alpha helix is a coiled structure stabilized by hydrogen bonds between amino acids, while the beta sheet consists of parallel or antiparallel strands that are also held together by hydrogen bonds. These structures contribute to the overall stability and functionality of proteins. The ability of polypeptides to adopt these forms allows for diverse protein architectures and functions.

Observe the structure of glucose and fructose and tell what does these two molecules forms?
Glucose forms a single-ring structure known as a pyranose, while fructose forms a five-membered ring structure known as a furanose. Both molecules are monosaccharides and are important components in the structure of larger carbohydrates.
Where do bonds form in secondary structure?
Two types of bond formation takes place in a secondary protein: 1. peptide bond due to amides 2. hydrogen bond
An element that has two allotropic forms called diamond and graphite?
Carbon has two allotropic forms called diamond and graphite. Diamond is a hard, transparent crystal structure, while graphite is a soft, dark crystal structure known for its lubricating properties.
What level of protein structure does a a-helix?
Some parts of a protein can have a helical structure - one of the most common secondary structures in proteins is the alpha helix.However, helix - especially double helix - will probably be more often used in the description of DNA, so be careful not to mistake the two.
What elements of protein secondary structure are present in this structure?
The protein structure contains both alpha helices and beta sheets, which are the two main elements of protein secondary structure.
What are the subgroups of protein?
There are four distinct levels of protein structure. The main two are primary, amino acid, secondary structure, and quaternary structure.

Describe the two types of secondary protein structure and explain the role of hydrogen bonds in maintaining the structure?
One secondary structure, α helix, is a delicate coil held together by hydrogen bonds every 4th amino acid. A structure with α helix is keratin, the material the human body uses to produce hair. The other secondary structure is β pleated sheet. In this one, two or more strands of β strands are connected by hydrogen bonds between parts of two parallel polypeptide backbones. This secondary structure is what spider webs are made of, and the hydrogen bonding makes it stronger than a strand of steel of the same weight. These secondary structures are unable to be formed without hydrogen bonding.

What causes the secondary structure of protein to differ in length from the primary?
The primary structure is a one or two dimensional structure, whereas the secondary structure is a three dimensional structure in which different parts of the protein molecule bend and twist due to the formation of hydrogen bonds between atoms. This makes the secondary structure shorter than the primary structure.
What are 2 secondary aminoacids?
Secondary amino acids are those that have a secondary amine group in their structure. Two examples of secondary amino acids are proline and hydroxyproline. Proline is unique because its amino group is part of a ring structure, which contributes to the rigidity of proteins. Hydroxyproline, derived from proline, plays a crucial role in the stability of collagen.
