Helps us grow and repair tissue

Makes enzymes, antibodies and hormones

We cannot function in life without it

Amino acids from protein help to maintain concentration and energy levels.

Helps make up proteins in blood such as haemoglobin

- An inactive adult should consume 0.8 grams of protein per kilogram of body weight (Dietary reference intake report for macronutrients)

- Factors such as activity level, weight, height and pregnancy can all affect a persons daily requirement of protein

- In average: 56–91 grams per day for the average male. 46–75 grams per day for the average female

# data[].attributes.body
- 17 Kilojoules per gram of protein

-> Our bodies contain around 100,000 different kinds of protein!
-> Proteins can have totally bizarre names! Take, for example, "Pikachurin", a retinal protein named after the Pokémon Pikachu. There’s also a protein literally called "Sonic Hedgehog", named after.. take a guess. There’s also a blue protein called "Ranasmurfin", inspired by the Smurfs.
-> Linguistically, the word 'protein' is drawn from the Greek "proteios", which means 'first rank' or 'primary'. It first became used around 1883.
-> Your hair is made of protein! Your hair, nails and lashes are all made of keratin, which is a protein. Also, keratin bonds to sulfur, and the more sulfur links it has, the curlier your hair is!
-> Gluten is actually a protein!  People with gluten sensitivity have difficulty digesting the protein itself.
-> Protein is in every cell of the human body, comprising approximately 20% of your body. The only substance we have more of is water. Protein's essential to life.
-> Most proteins only have a lifespan of around 2 days, and since our body can't store protein long-term, we need to replenish the supply by eating protein-rich foods everyday.

Protein structure is a 3D arrangement of atoms in an amino acid chain molecule.
Protein = polymers = formed from a sequence of amino acids
Proteins are built from a set of twenty amino acids, each containing a unique side chain.
Each gene in cellular DNA contains the code for a unique protein structure.

4 different protein structures:
- Primary
- Secondary
- Tertiary
- Quaternary structure

Primary Structure Of Proteins:
- Sequence of amino acids that make a polypeptide chain
- 20 different amino acids are found in proteins

Secondary Structure Of Proteins
- Alpha Helix: Polypeptide backbone could around helix axis in clockwise direction.
- Beta Sheet: Polypeptide backbone is fully extended

Tertiary Structure Of Proteins:
- Overall folding of the entire polypeptide chain into a specific 3D shape
- Often compact and globular shape

Quaternary Structure Of Proteins:
- Describes the way in which different subunits are packed together to form the overall structure of the protein.

Protein makes up roughly 17% of our body

Protein is the body’s main source of nitrogen which accounts for about 16% the weight of protein

Sources of protein in Australian and New Zealand diet are meat, poultry and fish (about 33%), cereals and cereal-based foods (about 25%), dairy foods (about 16%) and vegetables also provide about 8%

Proteins are found in both animals and plants
