The alpha-helix will plays an important role in terms of the shape and structure of the final protein. Since it orientates the amino acids, such as the functional group (or R group) facing the outside, then the properties of the amino acids will be the properties of the protein in that area. If the properties of the amino acids in an alpha helix are hydrophobic, then that protein will be hydrophobic in that area.

What can form a structure such as a helix or a sheet?
A polypeptide chain, which is the primary structure of a protein, can fold into secondary structures such as an alpha-helix or a beta-sheet.
How does collagen helix differs from alpha helix?
A collagen helix is less compact (because it goes into triple helices), and it is a left-handed helix. An alpha helix is more compact and hence requires more rotation of bonds to form (hence proline is not very common...has an imidazole ring). It is a right-handed helix, and goes into double helices instead.
The coiling of the protein chain backbone into an alpha helix is referred to as?
The coiling of the protein chain backbone into an alpha helix is referred to as the secondary structure. It is composed of several polypeptide chains.
Collagen and keratin are example of?
Keratin and Collagen are examples of proteins.
Does a helix refer to a protein's tertiary structure?
All of them. Tertiary is the overall 3D shape of the protein Quaternary is what proteins it is attached to and how Primary is the actual order of the amino-acids which make up the chain Secondary is the way that that chain coils or folds So 'helix' refers to the coiling of the chain. Hence it is the secondary structure.
What are helix proteins?
There are no known proteins such as helix proteins. Alpha helix is a secondary structure element found in proteins that formed by amino acids which can form helix. Other secondary structures are beta sheets and random coils.
What kinds of proteins can be found in cell membranes?
There are two kinds of proteins in a cell membrane: peripheral PROTEINS OR trans membrane proteins. Cell membranes are able to perform various functions only because of different membrane protein functions. Most of the membrane proteins have alpha helix structure.
What protein are found in plasma?
water ,minerals, proteins and disolved salt
What can form a structure such as a helix or a sheet?
A polypeptide chain, which is the primary structure of a protein, can fold into secondary structures such as an alpha-helix or a beta-sheet.
What type of helix forms RNA?
Alpha helix
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.
What did Herman branson invent?
The alpha helix
What is an alpha helix?
Hi, The DNA Helix is simply another name for DNA, and such name is used because DNA is in a double helix shape. The DNA is what determines who you are and therefore is found in every cell in our body. It is the genetic information of a human being and it contains genes, which are what determines our traits. For example, there are genes that control eye color, hair color, size of body...etc.
Once assemble What is the key to a proteins unique function?
Much of a proteins function is based on its 3 dimensional structure. How the Amino acids interact with eachother. Examples of 3 dimension structure are Alpha helix, and beta sheets. this is bull that is not it.
How does collagen helix differs from alpha helix?

An alpha helix is more compact and hence requires more rotation of bonds to form (hence proline is not very common...has an imidazole ring). It is a right-handed helix, and goes into double helices instead.
A helix refers to a proteins?
primary secondary
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.
