Proteins are large, complex molecules. They make up the enzymes that power many chemical reactions and the hemoglobin that carries oxygen in our blood. Protein is made from twenty-plus basic building blocks called amino acids. Because we don’t store amino acids, our bodies make them in two different ways: either from scratch or by modifying others. Nine amino acids—histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine—known as the essential amino acids, must come from food. Protein can actually be found in an abundance of foods, including those from animals and plants (such as beans, nuts, and seeds).

The National Academy of Medicine recommends that adults get a minimum of 0.8 grams of protein for every kilogram of body weight each day.

It’s the source of protein (the protein “package”), rather than the amount of protein, that likely makes a difference for our health. The table below shows an example of food “packages” sorted by protein content, alongside a range of components that come with it.

? Skin, hair and nail problems

Redness on the skin, brittle nails, thin hair, faded hair color are considered symptoms of protein deficiency.

? Loss of muscle mass

Muscle loss is one of the first signs of inadequate protein intake. Muscles are made up of mostly protein and if our body is protein-deficient, we tend to start losing muscles.

? Increased risk of bone fractures

Protein helps maintain the strength and density of bones. Not consuming enough protein content might weaken the bones and increase the risk of fractures.

? Risk of infections

Protein deficiency affects our immune system. An impaired immune system may disable the body against the fight of infections.

? Fatty liver

Another common symptom of protein deficiency is fatty liver or fat accumulation in liver cells.

? May inhibit proper body growth in children

Protein is essential for overall body growth. They are essential to the body growth of children.

Always consult a doctor in case you see these symptoms!

The roots of the word “collagen” go back to the Greek word kólla, which means glue.

Collagen is among the most abundant fibrous proteins and fulfills a variety of mechanical functions, particularly in mammals. Its main function is to provide structural integrity to tissue during mechanical stress.


Collagen is primarily found in the connective tissue (e.g. skin), but it is also present in the fibrous tissues of:
• Muscles
• Tendon
• Ligaments
• Skin
• Bones

It is also found in the tissues making up the:
• Blood vessels
• Bladder
• Digestive tract
• Heart
• Kidneys
• Gallbladder
• Teeth
• The cornea of the eye
• Cartilage
• Disks between the vertebrae
• In most extracellular matrix in general.
The fibrous nature and strength of collagen make it an ideal protective casing for your kidneys and other organs.


As a protein, collagen is made up of amino acids (arginine, glycine, hydroxyproline, and proline).
Amino acids are comprised of the elements: carbon, hydrogen, and oxygen.
Collagen is produced by fibroblasts (biological cells that help to form the structure of animal tissues).
The structure of a collagen protein is what gives it the unique strength your body needs.



It’s a triple helix—three chains twisting around each other.


There are 1,050 amino acids in each of the three chains that make up collagen. And they’re held together with hydrogens—the smallest atom.
Glycine is an amino acid that takes up the middle of the triple helix structure because it’s the only one that can fit.
These long fibers don’t just exist as single protein ropes. Collagen can come together to form striated horizontal sheets.
