Amino Acids: The Building Blocks of Protein

“Amino acids” -You might have heard this term in various health and fitness circles, especially on social media. But what is the meaning of amino acids, and why are they so important? In this blog, we explore the essential building blocks of protein and uncover their many benefits for our bodies.

What are Amino Acids?

Amino acids are organic compounds that combine to form proteins, which are critical for nearly every function in the human body. Think of them as individual Lego blocks that snap together to build a larger structure. Without these tiny but mighty compounds, our bodies wouldn’t be able to function properly.

Types of Amino Acids

You might be wondering, what are the types of amino acids? More than 300 amino acids have been discovered out of which 20 are required by the body for protein synthesis. They can be categorized into three main categories: essential, non-essential and conditionally essential amino acids.

Essential Amino Acids:

These are amino acids that our bodies cannot produce on their own, so we must obtain them from our diet. There are nine essential amino acids: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

Non-Essential Amino Acids:

These are amino acids that our bodies can produce and need not be taken from diet.

Conditionally essential amino acids:

These are usually non-essential but in times of illness or stress the body is unable to synthesize them in sufficient quantities and therefore they become essential.
So, what is amino acid in nutrition, and why should we care? Amino acids play a significant role in our overall health and well-being. They are involved in processes like building muscle, repairing tissue, and producing enzymes and hormones. Without them, our bodies would be like a car without fuel, unable to run smoothly.

Functions of Amino Acids

Now, let’s read more about amino acids benefits! These tiny compounds have a plethora of advantages for our health. Besides serving as building blocks for proteins, Amino Acids have multiple functions in cells, crucial for growth, development, and health. They are

• Fundamental Building Blocks of Protein
• Growth & Maintenance of Tissues
• Precursor of neurotransmitters; present in insulin, keratin, melanin pigment in hair, haemoglobin, and collagen
• Transport of Fatty Acids within cells
• Body Homeostasis, Acid-Base Balance
• Regulation of blood flow
• Role in immune function
• Energy Substrates

What Foods Have Amino Acids?

Now that you know how crucial these compounds are, you might be curious about what foods have amino acids. Proteins are found in a variety of foods, which ultimately provide the amino acids required by the body. Here are some sources:

• Meat and Poultry: Chicken, Fish & Eggs are good sources.
• Dairy Products: Milk, Curd & Paneer also contain these essential compounds.
• Plant-Based Sources: Legumes like Soya, Chickpeas, Lentils, Black Gram; Nuts and Seeds like Almonds, Pumpkin seeds, Chia seeds, and tofu are great options for vegetarians and vegans.

Did you know?

According to the Dietary Guidelines for Indians 2024 by ICMR-NIN, a combination of cereals, pulses, and millets provides most of the amino acids, which complement each other to provide good-quality proteins and essential amino acids. The guidelines further recommend that consuming an appropriate combination of cereals with pulses in the ratio of 3:1 or by substituting 30 g of recommended pulses with 80g of meat would improve the quality of protein and help meet the daily protein needs of a healthy individual. The addition of 250ml of milk for a healthy adult can further enhance the intake of Essential Amino Acids and meet the requirements of all Essential Amino Acids.

What Are Amino Acids Used For?

You might be asking yourself, what are amino acids used for in specific terms? Beyond the general health benefits, amino acids are also employed in medical treatments and supplements. For instance, they are used in intravenous therapies for patients who cannot consume food normally. They are also popular as supplements aimed at supporting athletic performance and providing energy.
However, it is very important to consult a nutritionist/healthcare professional before adding amino acid supplements to your regimen.

Conclusion

To sum it all up, the amino acid benefits for body functions are numerous. They are the unsung heroes of our diet, playing vital roles in nearly every bodily function. From supporting muscle growth to maintaining your skin and hair health, the health benefits of amino acids are too significant to ignore. So, the next time you’re planning your meals, think about how you can incorporate these essential compounds into your diet. Whether it’s through a bowl of chicken or fish curry, a hearty lentil soup, your body will thank you!
