之间的区别DHEAand DHA

Key Difference – DHEAvs DHA

DHEA（Dehydroepiandrosterone) and DHA (二十二烯酸) are important components present in the human body. Both compounds are involved in the different specific development and regulatory processes of the body. Even though both these compounds seem to possess similar types of acronyms, both compounds are totally different in the aspect of分类，，，，合成，，，，and function.DHEAis an endogenous类固醇hormone，，，，DHA是一个omega-3脂肪酸。这是关键区别在DHEA和DHA之间。

什么是DHEA？

DHEA（脱氢雌激素）通常称为雄烯醇。DHEA是一种内源性类固醇激素。它主要在肾上腺，大脑和性腺。DHEAis considered to have many potential functions within the body and is one of the steroids that circulates within the body most abundantly. In the brain, DHEA acts as a metabolic intermediate which involves in the synthesis of雌激素和雄激素类固醇性激素。

It also has the potential to act as a neurosteroid and neutrophin which the DHEA binds to an array of nuclear and cell surface proteins. Neurosteroids have the potential to involve in rapid alteration of neuronal excitability processes which is achieved through different interactions with cell surface receptors and ligand-gated ion channels. Neurotrophins are a class of proteins which involve in the induction of survival and development of神经元。因此，DHEA是重要组成部分中枢神经系统。

DHEA的合成机制涉及两种激素ACTH（肾上腺皮质激素）和GNRH（促性腺激素释放激素）。ACTH控制肾上腺皮质的Zona网状中DHEA的合成，而GnRH在合成DHEA期间调节性腺。这种内源性类固醇激素也在大脑中产生。胆固醇acts as a precursor in synthesizing DHEA through different酶。Out of the total DHEA synthesized in the body, higher percentage of DHEA is derived from the adrenal cortex and through desulfation of dehydroepiandrosterone sulfate (DHEAS).

更高的脱氢表雄酮在体内可以stimul生产ated through regular exercises. In primates, this is achieved through calorie restriction. Theories suggest endogenous DHEA production stimulation through calorie restriction lead to longer lifespans.

什么是DHA？

DHA（Docosahexaenoic Acid）被认为是一种omega-3脂肪酸，它作为人脑中的主要结构成分，即cerebral cortex，，，，retina of the eye and skin. DHA could be obtained from different sources which include maternal milk, fish oil or oil from specific types of藻类。

It also could be synthesized from alpha-linolenic acid,which is one of the two essential fatty acids that cannot be synthesized within the body. This mechanism is utilized mostly by草食动物和食肉动物这不取决于任何海鲜饮食来源。α-内酚酸基本上是在植物中合成的，是短的omega-3脂肪酸。获得较少量的海鲜的动物具有较低量的代谢途径产生DHA的能力。

鱼和其他多细胞生物通过光合微藻获得DHAheterotrophic这是海洋饮食来源。DHA的浓度沿着这些生态系统中的食物链增加。Crypthecodinium cohniiand精神分裂are different types of microalgae that involve in the commercial production of DHA. Since the DHA is synthesized using plant-based resources, it is 100% vegetarian.

在眼睛的大脑和视网膜的背景下，DHA是最丰富的omega-3脂肪酸。在视网膜中，大脑总不饱和脂肪酸的总数为DHA；它是40％。婴儿期在人类中的最佳DHA来源是通过母乳喂养从母乳中获得的。与其他任何来源相比，母乳的DHA百分比最高。在人类发展的后期，DHA是通过饮食获得的。

DHEA和DHA之间有什么相似之处？

• 两者都参与了人体的发展过程。

DHEA和DHA有什么区别？

DHEAvs DHA
DHEA是一种内源性类固醇激素。	DHA是omega-3脂肪酸。
合成
DHEA在肾上腺，大脑和性腺中合成，并通过胆固醇衍生而成。	DHA通过修改而合成Escherichia coli,alpha linolenic acid and through photosynthetic microalgaeCrypthecodinium cohniiand精神分裂。
Function
DHEA充当男性和女性性激素的前体，包括睾丸激素和雌激素。	DHA是发育中大脑的重要结构和功能组成部分，对心脏的健康很重要。

摘要 - DHEAvs DHA

DHEA是一种内源性类固醇激素。它主要是在肾上腺，大脑和性腺中合成的。DHEA是中枢神经系统的重要组成部分，该系统在神经元的发展和激发中起作用。DHA是omega-3脂肪酸。DHA通过修改而合成Escherichia coli,alpha-linolenic acid and through photosynthetic microalgaeCrypthecodinium cohniiand精神分裂。两种化合物都参与身体的不同特定发育和调节过程。这是DHEA和DHA之间的区别。
