PROTEINS⠀
⠀
⠀
What are proteins?⠀
⠀
**Derived from Greek Word ‘Proteins’ meaning of utmost importance or holding first place.It is a complex form of amino acids.⠀
⠀
Amino Acid- Simple Organic compound containing both a carboxyl group(-COOH) and an amino(-NH2) group⠀

⠀
Proteins are major structural component of muscle and other tissues of the body.⠀
⠀
How body uses proteins?⠀
⠀
Proteins are responsible for repair,growth and recovery of muscle fibres⠀
⠀
**ACTS AS ANABOLISM PART OF METABOLISM⠀
⠀
Some proteins are hormones.They help in transportation between cells.Ex-Insulin, Glucagon etc.⠀
⠀
Some proteins act as a structural pillar of tissues basic work is to provide strength.⠀
Example- Elastin in cartilage,collagen in bones and ligaments,keratin in hair and nails.⠀
⠀
Protein forms antibodies that fight infection and increases immunity.⠀
⠀
**FERRITIN PROTEINS ACTS AS RESERVOIR AND STORES IRON⠀
⠀
These are the function where protein plays its role but essentially helps in muscle building.⠀
⠀
**EXCESS PROTEIN IS EITHER CONVERTED INTO ENERGY(GLUCONEOGENESIS PROCESS) OR CONVERTED INTO FATS⠀

⠀
Types of proteins(In th slide)-⠀
Essential⠀
Conditionally non-essential⠀
Non-essential⠀
⠀
Metabolism of proteins-⠀
⠀
The cells in the intestines cannot absorb wholr protein,they need to be broken down into small chains of two or three amino acids known as peptides⠀
⠀
Break down first starts in stomach where HCL and pepsin break the bonds into simpler amino acids.⠀
⠀
Now, Pancreas releases digestive enzymes(Trypsin) into the small intestine.⠀
⠀
Now,trypsin further breaks this chain and transport the smaller peptide to muscle fibres through bloodstream.⠀
⠀
**RENNIN IS AN ENZYME THAT IS PRESENT IN INFANTS FOR BREAKDOWN OF MILK PROTEIN.⠀
⠀
How much protein you should intake-⠀
For sedentary lifestyle-0.8g/kg⠀
For active lifestyle (Athlete or strength trainee)-2g/kg/day.
