What is protein composed of?

Answer 1

Proteins are composed of polypeptides which are in turn composed of amino acids which are organic molecules and are composed of:

Carbon

Hydrogen

Oxygen

Nitrogen

And a variable group (Can be a carbon, hydrogen, or sometimes a sulfur)

All amino acids share a common structure, where an amino group is bonded to a carbon atom (designated the alpha carbon) which is in turn bonded to carboxylate (carboxyllic acid), a hydrogen and the variable group often denoted as the R group (except glycine which has a H for an R group). Amino acids combine through a dehydration mechanism which removes a hydroxyl group from the carboxyllic acid of one amino acid and the proton from another amino acid's amino group: the resultant bond is referred to as a peptide bond and is very stable and rigid (planar) due to delocalisation of the double bond of the carbonyl over to the N atom

Answer 2

Proteins are composed of long chains of organic molecules called amino acids. There are 20 different types of amino acids that can be combined in various sequences to form different proteins. These amino acids are linked together through peptide bonds to create the protein's structure.
