Difference Between BCAA and Amino Acids

Thekey differencebetween BCAA and amino acids is that theBCAA is branched chain amino acid that has aliphatic side chains with a branch whereas the amino acids are organic compounds containingaminegroups,carboxylicgroups, and a specific side chain.

Amino acids are the building blocks of proteins. The side group (R) of the amino acid determines the properties of the amino acid. Therefore, this side group is specific for amino acids. In other words, different amino acids have different side groups. However, BCAAs have an additional uniqueness; a central carbon atom bound to three or more carbon atoms.

What is BCAA?

BCAA is branched chain amino acid that has analiphaticside group with branches. Therefore, this creates a central carbon atom bound to three or more carbon atoms. Among proteogenic amino acids (Proteinogenic amino acids are amino acids that are incorporated biosynthetically into proteins during translation), there are three BCAAs; leucine, isoleucine and valine. These are very important amino acids among the essential amino acids. An example of a non-proteinogenic BCAA is 2-aminoisobutyric acid. The plastids in plant cells are the main point at which these compounds create. These compounds have many metabolic and physiologic roles.

BCAA在代谢中的作用;

Protein synthesis
Protein turnover
Metabolism of glucose
Helps in the signalling pathways

在生理学中的作用；

Helps the immune system
Important in brain functioning

In addition, these compounds are important in the fitness industry. Ex: we take them as standalone powder or tablet, as an ingredient in pre-workout formulas, etc. It is a highly recommended supplement for building muscle mass, to reduce body fat, etc.

Figure 01: The Pathway of BCAA in our Body

当我们进行锻炼以减少体内卡路里时，我们的身体倾向于使用肌肉蛋白作为能源。然后，我们体内蛋白质合成的速率应超过蛋白质分解的速率，因为否则我们可能会失去组织和肌肉。BCAA可以增加或维持该蛋白质合成速率。

What are Amino Acids?

Amino acids are the building blocks of proteins. These are organic molecules containing amine groups (-NH₂), carboxylic groups (-COOH) and a specific side chain (-R). These molecules can bind with each other to form protein molecules.

The bond between two amino acids is apeptide bond。积累氨基酸分子的化学元素是碳（C），氢（H），氧（O）和氮（N）。这些分子在我们体内的作用包括蛋白质的残基，神经递质转运和生物合成。

What is the Difference Between BCAA and Amino Acids?

BCAA is branched chain amino acid which has an aliphatic side group with branches. It has many metabolic and physiologic roles such as promote protein synthesis and turnover, signalling pathways, and metabolism of glucose along with some physiological roles such as helping the immune system and brain function. Amino acids are the building blocks of proteins. The roles of these molecules inside our body include the production of proteins, neurotransmitter transport and biosynthesis.

概括– BCAA vs Amino Acids

BCAA是一种氨基酸的形式。BCAA和氨基酸之间的差异是BCAA是分支链氨基酸，具有脂肪族侧链，带有分支，而氨基酸是含有胺基，羧基和特定侧链的有机化合物。
