Yes. The alpha carbon, from where the amino group, the carboxylic group and the side chain (or R group) are attached.
By forming chemical bonds with two hydrogen atoms and a carbon atom, the nitrogen atom now the R group, and the hydrogen atom are all bonded to a central carbon atom (circled). They include alanine, valine, leucine and isoleucine.
The amino acids are distinguished by the R groups which determines what amino acid it is.
Some elements that are always present in amino acids are carbon, oxygen, and nitrogen. Hydrogen is also present in amino acids.
Each amino acid consists of an alpha carbon atom to which is attached, a hydrogen atom, an amino group, a carboxyl group and one of 20 different "R" groups.
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)
an oxygenThe central carbon atom in an amino acid is bonded to an amino functional group, a carboxyl functional group, a side chain, and hydrogen.
the carbon in carbonyl function
It has an amino goup (NH2) and a carboxyl group (COOH)
An amino group and an R group
Amino Acids are linked in ribosomes.
a central carbon, a hydrogen atom, an amino group, and a carboxyl group
All amino acid are composed of a central carbon (C) bonded to a hydrogen (H), an amine group (NH2), and a carboxylic acid group (HCO3). In addition, each amino acid has its own particular side-chain bonded to the central carbon.
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.

Basic structure of protein. Combinations of these amino acids form peptides and eventually large protein structures. Could be anything from haemoglobin in blood to myosin in muscles.
