Protein: The Ultimate Guide 💪✨

What is Protein?

A “Bodybuilding Nutrient” essential for growth, repair & maintenance.
Made up of amino acids; contains nitrogen (unique from carbs & fats).
Found in muscles (50%), bones (20%), skin (10%), and other tissues.
Key Functions
1️⃣ Bone Health

Collagen forms the framework for bones, teeth, tendons, & ligaments.
Stores calcium & phosphorus.
2️⃣ Growth & Repair

Nitrogen supports cellular growth & tissue repair.
3️⃣ Essential Compounds

Enzymes (pepsin), hormones (insulin), and blood-clotting proteins (fibrin).
4️⃣ Muscle Function

Actin & myosin enable muscle contraction.
5️⃣ Immunity

Antibodies (immunoglobulins) fight infections.
6️⃣ Nutrient Transport

Lipoproteins move fats; retinol-binding protein carries vitamin A.
Amino Acids: Protein’s Building Blocks

Essential: From diet (e.g., leucine, lysine).
Non-Essential: Made by the body (e.g., glycine, alanine).
Conditionally Essential: Needed during stress (e.g., glutamine).
Special Roles

Energy (BCAAs), immunity (glutamine), growth hormones (arginine).
Liver detox (cysteine) & neurotransmitter production (tyrosine).
Protein Sources

First-Class (High BV): Whey, eggs, chicken, fish, milk, paneer.
Second-Class: Pulses, beans, legumes, cereals, nuts.
Protein Needs (Based on Activity)

Sedentary: 0.8–1 g/kg body weight.
Beginner: 1–1.5 g/kg.
Advanced: 2–3 g/kg.
Absorption Speeds

Fast: Whey, egg whites.
Moderate: Whole eggs, whey with milk.
Slow: Paneer, yogurt, chicken.
Quick Tips

Aim for a Positive Nitrogen Balance to support muscle growth.
Protein digestion begins in the stomach with enzymes like pepsin.
Absorbed in the small intestine and distributed via the bloodstream.
Fuel your body with high-quality protein for optimal health & performance! 💥
