Protein and Amino Acids
Introduction
Organic compound with high MWSimilar CHO, fat but contained S Growth and repaired Essential for blood, tissue, enzymes,
immune and hormone (Riis, 1983; McDonald et al., 2011)
Amino acid characteristics
Are biologically important organic compounds made from amine (-NH2) and carboxylic acid (-COOH) functional groups.
Amino acid, carbon, hydrogen, oxygen, and nitrogen.
20 standard amino acids, 9 of the 20 standard amino acids are called “essential”
Amino acid characteristics

Protein characteristics
More than 100 molecule AA Protein are large biological molecules
consisting of one or more chains of amino acid.
Proteins perform a vast array of functions within living organisms
A polypeptide is a single linear polymer chain of amino acids bonded together by peptide bonds between the carboxyl and amino groups.

OpenStax College (2013)
Primary structure
such as DNA, RNA or typical
intracellular protein
Secondary structuresuch as proteins and nucleic
acids (DNA/RNA)
Tertiary structure
Protein or any other macromolecule is its three-
dimensional structure
Quaternary structure
Arrangement of multiple folded protein or coiling protein molecules in a multi-subunit
complex
