How do individual amino acids differ?
Amino acids differ according to their R groups. All amino acids have an amino group, a carboxyl group (organic acid), and a hydrogen atom attached to a central carbon atom. Also attached to the central carbon atom is an R group that varies according to the amino acid. Refer to the related links for illustrations.
Are Amino acids are the same except for their R group?
No, amino acids are unique in that they have the same basic structure with an amino group, a carboxyl group, and a hydrogen atom attached to a central carbon atom, but differ in their side chain or R group, which gives each amino acid its specific properties and characteristics.
What do the 20 amino acids vary in?
The amino acids vary in the side groups, usually designated by "R" on the chemical structures for amino acids. The invariant parts are the amino group (NH2-), central (-CH-) group, and the carboxyl (-COOH) group. Connected to the central carbon on the (-CH-) group is a side group which is part that varies.
Why amino acid called alpha amino acid?
Amino acids are called alpha amino acids because the amino group (-NH2) is attached to the alpha carbon atom in the molecular structure of the amino acid. This alpha carbon is the carbon atom next to the carboxyl group (-COOH) in the amino acid molecule.
Are amino acids attached to a glycerol backbone?
A 3 carbon chain .
How do amino acids differ?
Amino acids differ according to their R groups. All amino acids have an amino group, a carboxyl group (organic acid), and a hydrogen atom attached to a central carbon atom. Also attached to the central carbon atom is an R group that varies according to the amino acid. Refer to the related links for illustrations.
Which of the following is not attached to the central carbon atom in an amino acid?
In an amino acid, the central carbon atom is attached to an amino group, a carboxyl group, a hydrogen atom, and an R group (side chain). Therefore, the central carbon atom is not attached to a phosphate group in an amino acid.
How do individual amino acids differ?
Amino acids differ according to their R groups. All amino acids have an amino group, a carboxyl group (organic acid), and a hydrogen atom attached to a central carbon atom. Also attached to the central carbon atom is an R group that varies according to the amino acid. Refer to the related links for illustrations.
How do acids differ?
Amino acids differ according to their R groups. All amino acids have an amino group, a carboxyl group (organic acid), and a hydrogen atom attached to a central carbon atom. Also attached to the central carbon atom is an R group that varies according to the amino acid. Refer to the related links for illustrations.
What function groups make up an amino acid?
An amino acid consists of an amino group, a carboxyl group, a hydrogen group, and a side group (R group) all attached to a central (alpha) carbon.
What do amino acids always have?
All amino acids share a common structure. The have a carboxyl group (COH), an amine group (NH3), a hydrogen, a variable "R" group, and a central carbon to which all these groups are attached.
What group varies between amino acids?
All amino acids have an acidic group (--COOH) and an amino group (H2N--), each linked to a central carbon by a separate covalent bond. They differ by the R group (remainder group) attached to the central carbon atom. (Source: Inquiry Into Life by Sylvia S. Mader)
Does one molecule lose 3 OH ends in amino acids?
No, amino acids do not lose 3 OH ends. Amino acids have one carboxyl group (COOH) and one amino group (NH2) attached to a central carbon atom. The central carbon atom also has a side chain (R group) attached to it.
What are the four groups that surround the central carbon atom in an amino acid?
The four groups that surround the central carbon atom in an amino acid are the amino group (NH2), the carboxyl group (COOH), a hydrogen atom (H), and an R-group (side chain) that varies among different amino acids.
What distinguishes one amino acid from another in terms of their unique characteristics?
Amino acids are distinguished from each other by their unique side chains, which are different chemical groups attached to a central carbon atom. These side chains determine the specific properties and functions of each amino acid.
Amino acids always have two groups attached what are they?
A carboxyl and an amino
Are Amino acids are the same except for their R group?
No, amino acids are unique in that they have the same basic structure with an amino group, a carboxyl group, and a hydrogen atom attached to a central carbon atom, but differ in their side chain or R group, which gives each amino acid its specific properties and characteristics.
