HUMAN NUTRITION

Detailed explanation-1: -Amino acids are molecules containing an amine group, a carboxylic acid group, and a side-chain that is specific to each amino acid. The key elements of an amino acid are carbon, hydrogen, oxygen, and nitrogen. They are particularly important in biochemistry, where the term usually refers to alpha-amino acids.

Detailed explanation-2: -An amino acid is an organic chemical. Organic chemicals contain carbon-hydrogen bonds. All amino acids have the same basic structure. Each molecule has a central carbon atom linked together with a basic amino group, a carboxylic acid group, a hydrogen atom and an R-group, or side-chain group.

Detailed explanation-3: -Chemically, an amino acid is a molecule that has a carboxylic acid group and an amine group that are each attached to a carbon atom called the carbon. Each of the 20 amino acids has a specific side chain, known as an R group, that is also attached to the carbon.

Detailed explanation-4: -Nitrogen is an essential element for all forms of life and is the structural component of amino acids from which animal and human tissues, enzymes, and many hormones are made.
