Alanine is a nonessential amino acid that the human body can produce from other amino acids, and it does not need to be obtained from food. It is usually high in most people's blood and is one of the amino acids concentrated in protein foods.

在所有氨基酸中，它是廣泛用于蛋白質構建的氨基酸之一。它被認為是一種糖原氨基酸，由丙酮酸和支鏈氨基酸（BCAA）合成而成，包括纈氨酸，亮氨酸和異亮氨酸。

Among all amino acids, it is one of the amino acids widely used in protein construction. It is considered to be a glycogen amino acid synthesized from pyruvic acid and branched chain amino acids (BCAA), including valine, leucine and isoleucine.

What effect does alanine have on the body? What is the function of alanine? Some important functions include:

在將糖（葡萄糖）轉化為能量方面發揮作用-它參與了組織和肝臟之間發生的葡萄糖丙氨酸循環；加工B族維生素；分解色氨酸和維生素B6；幫助酸代謝。

It plays a role in converting sugar (glucose) into energy - it is involved in the glucose alanine cycle that occurs between tissues and the liver; processes B vitamins; breaks down tryptophan and vitamin B6; and helps with acid metabolism.

增強免疫力；促進色氨酸的代謝；形成肌肽，鵝肌肽和泛酸（維生素B5）；為大腦和神經系統提供能量。

Enhance immunity; promote tryptophan metabolism; form carnosine, goose carnosine and pantothenic acid (vitamin B5); provide energy for brain and central nervous system.

幫助建立和修復肌肉組織；幫助肝臟；保護細胞免受氧化損傷；幫助維持正常膽固醇水平。

It helps build and repair muscle tissue, helps liver detoxification, protects cells from oxidative damage, and helps maintain normal cholesterol levels.
