What are DHA and ARA? What is the difference between DHA and AA ARA?

Shankayou DHA: ARA** ratio is very good.

1. DHA is the abbreviation of docosahexaenoic acid, commonly known as brain**. DHA is a major component of the growth and maintenance of nervous system cells, an important component of the brain and retina, with a content of up to 20% in the human cerebral cortex and the largest proportion in the retina of the eye, accounting for about 50%, so it is essential for the intelligence and vision development of fetal infants.

2. Ara is the abbreviation of arachidonic acid, also known as inflammatory factors. ARA is an essential fatty acid in early childhood, and the deficiency of ARA may have serious adverse effects on the development of human tissues and organs, especially the development of the brain and nervous system. After growth, the human body can be converted from essential fatty acids linoleic acid and linolenic acid, so it is a semi-essential fatty acid.

AA, ARA is the same thing, i.e., eicosatetraenoic acid, and the main differences from DHA are as follows:

1. Different ways of existing.

1. DHA: It exists in various fish oils, especially in the fat of deep-sea fish.

2. Ara: Separation of C4 fraction by extractive distillation method, can also be obtained by absorption method, molecular sieve method, complexion method, etc.

Second, the characteristics are different.

1. DHA: Pure DHA is colorless, tasteless, liquid at room temperature, fat-soluble, soluble in organic solvents, insoluble in water.

2. Ara: It has the functions of stimulating the uterus, prolonging the gestation period of rats and inhibiting the secretion of gastric acid. Exogenous arachidonic acid has a contractile effect on the rabbit aorta, so it is speculated that it may be an endothelium-dependent contractile factor (EDGF).

Third, the melting point is different.

1. DHA: The melting point is .

2. Ara: melting point.

AA and ARA both refer to arachidonic acid, and DHA is docosahexaenoic acid, both of which are essential fatty acids and play an important role in promoting brain development. For example, DHA is a great help for brain development. The difference is that AA and ARA foods are abundant** and can be obtained in sufficient quantities through meals.

As an important and indispensable component of the brain and retina, DHA is an important substance to promote the brain and vision development of 06-year-old babies, so 0-6 year old babies especially need to supplement a sufficient amount of DHA.

DHA and ARA The essential fatty acids linoleic acid and linolenic acid are the precursors of ARA and DHA, respectively, DHA is called the brain** and is very important for brain and retinal developmentARA is also known as arachidonic acid, which is also important for the growth and development of the human body. DHA and AA are rapidly concentrated in the brain during the third trimester and neonatal period, and DHA is also abundant in the retinal photoreceptor, mainly through the placenta or breast milk. Therefore, preterm birth and lack of breast milk will affect the DHA level in the baby, and it is necessary to pay attention to the appropriate DHA and AA supplementation from formula.

Mothers should choose suitable formula milk powder according to the baby's situation, such as premature babies should choose premature infant formula that reduces the proportion of vitamins, fats and other nutrients, and increases DHA, taurine and other nutrients4-6 months old baby choose no starch, moderate protein content, easy to digest and absorb formula;6 months to 3 years old babies have rapid intellectual development, it is best to choose formula containing DHA and AA ingredients. In addition, parents are reminded to pay special attention to the ingredient labeling on the cans when purchasing formula milk powder, to identify whether it contains palm oil and whether infant milk powder containing palm oil will affect calcium absorption.

ARA is the abbreviation of the chemical name of peanut celery brigade tetraenoic acid, and DHA is the English abbreviation of the chemical name of docosahexaenoic acid. Both of these substances are long-chain unsaturated fatty acids, which are important substances for the nervous system, especially the brain, to carry out physiological activities. Ara (also known as AA), scientific name arachidonic acid, is an N-6 type long-chain polyene that is not saturated.

Unsaturated fatty acids Fatty acids other than saturated fatty acids (fatty acids without double bonds are called saturated fatty acids, and the main fatty acids of all animal oils are saturated fatty acids, except for fish oil) are unsaturated fatty acids.

Unsaturated fatty acids are a kind of fatty acids that constitute body fat, and they are indispensable fatty acids for the human body. Unsaturated fatty acids are divided into monounsaturated fatty acids and polyunsaturated fatty acids according to the number of double bonds.
