Protein can be in four different structures:

# data[].attributes.body
1) Primary protein structure : a chain of amino acids
2) Secondary protein structure: folded in a repetitive pattern by hydrogen bonding
3) Tertiary protein structure: 3D pattern
4) Quaternary protein structure: protein is made up of more than 1 amino acid chains.

Proteins are necessary for the proper structure, function and regulation of all tissues and organs in the body. It enables both the repair and growth of tissues to replace old ones while also being necessary for metabolic reactions such as digestion, energy production and muscle contractions

150mg of Ca excreted for every 50g of dietary protein

Creutzfeldt Jakob disease is a fatal degenerative brain disorder that often involves dementia. It occurs due to the mis-folding of proteins to cause irregular structures known as a prions.

Protein contributes from 18 to 20% of our weight

# data[].attributes.body
There are 100,000 different protein in our body

Protein is made up of both essential and non-essential amino acids. Essential amino acids are those which are sourced from a persons diet (i.e is found in food) and non-essential are those produced in the body.

Eating less protein results in weight loss.

Consuming insufficient protein can actually make it harder for individuals to lose weight as proteins help keep you full and trigger metabolic reactions. Without it, it will be harder for the body to metabolise and the chances are you will lose muscle instead of fat.

Fun facts about protein

They have a really short life span, most of them have 2 days or less.
human hair and nails are made of protein.
because of the similarity, animal protein can be more easily digested than plant-based protein by human body.
