What causes a difference in amino acids?
The R groups of amino acids cause the difference in amino acid. The R group is joined at the alpha carbon of amino acid. There are four group joined at one carbon, viz. an acid group --COOH, and an amino group --NH3, one hydrogen and a functional group (R group). Except R group all the groups are same in every amino acid. So on the basis of R group i.e., functional group, there occur differences EITHER it is polar or non-polar nature OR acidity or basicty.
Which part of amino acid is unique?
The side chain or R-group
What happens when you change the R group of an amino acid?
It will become a different amino acid. For example, the r group for the amino acid leucine is greatly different than that of glycine. The r group is the identifying portion of an amino acid, otherwise only the amine group and the carboxyl groups exist. At the link is a picture of the various amino acids. You can see the carboxyl groups [COOH] and the amine groups [NH3] are always there, but the rest of the molecule changes.
The 20 different amino acids found in polypeptides exhibit different chemical and physical properties because of different?
Amino acids exhibit different chemical and physical properties because of their R groups. An amino acid is asymmetric, meaning that it is a carbon bound to 4 different elements. Three out of the four are the same in every amino acid. These three are: an amino group, a Hydrogen, and a carboxyl group (otherwise known as an acid). Hence the name Amino Acid. The 4th grouping is called the R group, and it is different for every amino acid. This R group determines the shape of the amino acids and the shape determines function.
What are the parts of amino acid?
Amine or amino group, carboxylic acid group, 'R' or variable group, central carbon atom
Why is the R group in amino acids?
The R group in an amino acid are what make that amino acid unique.
Why is the R group in amino acids important?
The R group in an amino acid are what make that amino acid unique.
What part of an amino acid is not the same in all amino acids?
The "R" group is different in different kinds of amino acids. The "R" group can be a number of different molecules that are attached to the alpha carbon.
What is the R-group of Alanine?
An R group is the chemical group attached to the alpha carbon in an amino acid. In proteins all amino acids have the same basic structure and vary only in their R group. There are 20 standard amino acids found in proteins, which all have different R groups. For example an amino acids with Hydrogen from its R group is glycine, and one carbon with 3 hydrogens (a methyl group) is the R group for alanine.
What group do amino acids always contain?
The amino acids are distinguished by the R groups which determines what amino acid it is.
What part of the amino acid is different in each amino acid different?
The "R" group
What is R group in amino acid?
lanthionine
What amino acid has a phenyl group as its R group?
The R-group in the phenylalanine amino acid is: CH2-benzene ring
Which amino acid possesses the least extensive r group?
Glycine is the simplest common amino acid. It is characterized by the presence of a hydrogen atom as its R-group.
Which three components are common to all amino acids?
The 20 amino acids vary in structure by the R-group, otherwise all amino acids are the same in structure. All amino acids have a carboxyl group, an amino group, an R-group, and a hydrogen which are all bonded to a central carbon. It is the R-groups that make the amino acids react in different ways and alter the structure of the protein.
What is the variable of acid?
The variable of amino acid is called the R group.
What causes a difference in amino acids?
The R groups of amino acids cause the difference in amino acid. The R group is joined at the alpha carbon of amino acid.
