Okra: Complete Amino Acid Profile

Okra ‐ Amino Acids List

Introduction

Okra, also known as Abelmoschus esculentus or Hibiscus esculentus, is an edible plant belonging to the mallow family and is believed to have originated in Africa. The okra pod is often described as being “prickly” due to its thin, sharp-pointed outer skin. Okra is considered a very nutritious food with many advantageous dietary benefits including high levels of antioxidants, vitamins and minerals. Additionally, there are certain amino acids found in okra that may contribute towards human endurance and overall health.

Amino Acids Overview

Amino acids are considered organic compounds that form the basis of proteins and are necessary for proper growth and development in humans. Although composed of different classes, amino acids can be divided into two main categories: essential and nonessential. Essential amino acids cannot be naturally produced by the body; thus, they must be consumed through diet sources such as meat, eggs, legumes, seafood, dairy products and even plants like okra. Non Essential Amino Acids on the other hand are those which the body is able to produce by itself and therefore do not need to be ingested for their synthesis. It should be noted however, that it is not possible for any single plant to provide all 20 essential amino acids required.

Composition of Amino Acids Found In Okra

Research has found that okra contains nine essential amino acids (histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine). Out of the nine, four are classified as branched chained amino acids including histidine, leucine, isoleucine, and valine. Leucine, isoleucine and valine together compose one third of protein content within the human body and are important components of metabolism. In addition to these essential amino acids, okra contains two notable nonessential ones - asparagine and glutamine. Asparagine works closely with glycine in order to maintain vital hemoglobin functions while glutamine helps protect muscle tissue from breakdown during times of strenuous physical activity1.

Benefits of Amino Acids Found In Okra

The presence of essential amino acids found in okra is helpful for both preventing and compensating conditions caused by inadequate nutrition. Histidine contained in the vegetable assists in maintaining healthy bones and cell regeneration2. Likewise, Lysine is beneficial for increasing absorption of calcium3, and Methionine promotes formation of red blood cells4. Athletes in particular benefit from consuming more food items containing branched chain amino acids due to their major role played in energy production5. Additionally, high levels of aspartic acid and glutamic acid found in okra assist in enhancing oxygen uptake6. Even further, glutamic acid specifically helps improve exercising performance7. Finally, tryptophan contained in okra is important for physiological purposes such as favoring natural sleep, inducing relaxation, decreasing anxiety, and fostering moodiness8.

Conclusion

In conclusion, the wealthy combination of essential, non-essential and branched amino acids present in okra makes it a great nutritional choice for people of all ages who are looking to stay fit and healthy. From juvenile growth and development to senior longevity and sturdiness, okra can aid in promoting general wellness and well-being. All of this evidence reinforces how powerful okra can be when integrated into daily diets worldwide.
