미량으로도 성장을 저지시키거나 결핍증을 초래하고, 일부를 제외하고는 체외에서 합성되지 않거나 합성된다 하더라도 필요량을 충족할 수 없어 외부로부터 공급받아야 하는 비타민. 땀을 많이 흘리는 여름은 다른 계절에 비해 체력이 떨어지게 마련인데, 이때 비타민 섭취는 필수. 오메가3지방산과 오메가6지방산, 비타민E에 대해 좀 더 자세히 알아보고, 술과 담배를 좋아하는 남편, 한창 성장하는 아이들, 관절이 좋지 않는 어르신들을 위한 맞춤형 비타민을 준비해보자.

어분의 미지성장인자(UGF)중 하나는 오메가($\omega$)-3 지방산 - 동물성 단백질의 왕자라고 할 어분은 전 세계적으로 양어사료는 물론 양계사료 및 이유자돈 사료로 널리 이용되어 왔다. 특히 어분의 미지성장인자(UFG ;Unknown Growth factor)인 오메가($\omega$)-3 지방산은 면역체세포의 활력도 증진시키는 작용도 하고 있는 것으로 밝혀졌다. 하지만 1970년대 초, 미국의 어분생산량이 급격히 감소하면서부터 가축사료의 단백질 공급원으로서 어분이 차지하던 자리는 대두박 등의 식물성 박류에게 넘겨줄 수 밖에 없었다. 그럼에도 불구하고, 단미사료의 80($\%$를 수입에 의존하여, `보세가공 축산`이라는 부정할 수 없는 꼬리표까지 달고 있는 우리나라가 어분의 생산량만큼은 충분하다고하니 반가운 일이 아닐 수 없다. 어분의 사료영양학적 가치를 제대로 파악하여 우리나라 부존자원의 활용을 높이는 것은 국가적으로도 이익이 아닐수 없을 것이다. 본고에선 그러한 어분의 영양학적 특징과 미지성장인자(未知成長因子)의 역할 중 오메가($\omega$)-3 지방산 및 단백질 공급원으로써의 어분을 양계사료 및 이유자돈 사료에 이용함으로써 얻어지는 이익에 대해 논하고자 한다.

This study was investigated the biochemical mechanism on reducing blood lipids in second-generation rats fed diet with different omega 6 to omega 3 fatty acid ratio. The experiment treatment groups were classified into the groups with the omega 6 to omega 3 ratios of 0 (control group), 1:1, 8:1, and 19:1, respectively. The levels of the blood triglyceride, total cholesterol, low density lipoprotein-cholesterol (LDL-C), aspartate aminotransferase (AST), alanine aminotransferase (ALT) and glucose were lowest in the group with the omega 6 to omega 3 ration of 1:1. The levels of high density lipoprotein-cholesterol and phospholipid were highest in the group with the omega 6 to omega 3 ration of 1:1. The HMG-CoA reductase activity was suppressed in the groups with the omega 6 to omega 3 ratio of 1:1 and 8:1 compared with that in the control group, but the excretion of sterol through feces was promoted. The blood omega 6 to omega 3 ratio decreased in a concentration-dependent manner depending on the increase in the omega 6 to omega 3 ratio within the ingested diet. The results of this study demonstrated a new finding that when the parent generation and second-generation rats ingested the diet with the omega 6 to omega 3 ratio of below 8:1, harmful lipids in the blood were reduced, the liver functions were maintained, and the growth was promoted due to the nutrient metabolism activation mechanism.

해산어류는 담수어나 육상의 포유동물과는 달리 사료내의 18탄소 전구체의 지방산에서부터 충분한 양의 필수지방산을 생합성할 수 없기 때문에 사료를 통하여 이들 성분을 공급해야만 한다(Yamada, 1980). 최근에는 사료 내에 필수지방산의 한 종류인 EPA(20:5n-3)가 충분히 함유되어 있다고 하더라도 DHA(22:6n-3)로 전환되는 속도가 늦기 때문에 해산어 자치어의 DHA요구를 충족시킬 수가 없다는 것이 밝혀지고 있다(Bell, 1995; Sargent, 1997). (중략)

To evaluate the effects of n-3 and n-9 fatty acid combination on broiler chicks, diets containing the combinations of five different fat sources including flaxseed oil, fish oil, EPA, DHA and olive oil were provided, and all chicks were processed at 4 weeks of growth. Liver, breast and thigh samples were collected and fatty acid composition and/or CIE $L^*$, $a^*$ and $b^*$ measurement were measured. Also, live chick and liver weights were weighed and the ratio was provided as an evidence of fat accumulation in liver. No significant difference was determined in both live and liver weight ratio and liver color. EPA was low in FHO as compared to livers from others. In contrast, DHA was significantly high in FHO. In broiler breasts derived from FDO, AA and n-3 fatty acid content was high, but only numerical differences of EPA and DHA were determined in breasts from FDO. The thighs from FHO showed high in EPA, DHA and n-3 fatty acid content but had low in AA and n-6 to n-3 ratio. Therefore, the results indicate that broiler chicken diets containing either FDO or FHO may be possible combination diets increasing n-3 polyunsaturated fatty acids in broiler chicks.

Eicosapentaenoic acid (EPA, 20：S n-3) 및 docosahexaenoic acid (DHA, 22：6n-3)는 수산식품에 특징적으로 다량 함유되어 있는 대표적인 e3 지방산이다. 이들 지방산은 해양생물의 기초생산자인 해양미세조류로부터 생산되고 이들은 먹이연쇄에 의하여 소형, 대형 해양생물을 거쳐 최종적으로는 인간에 의하여 섭취된다. N-3 지방산에 관한 연구는 최초 어유에 대한 역학조사(Dyerberg and Bang, 1978; Bang et al., 1980; Hirai et al., 1980)가 계기가 되어, 오늘날 오메가-3지방산의 다양한 생리작용이 밝혀지게 되었다. (중략)

The fatty acid composition, selected minor components, and the oxidative stability of the mixed edible oil (perilla seed oil and rice bran oil, 3:7 (v/v)) were analyzed. The fatty acid composition of the mixed oil was 32.1% of oleic acid, 30.6% of linoleic acid, 21.4% of linolenic acid, 13.0% of palmitic acid, and 1.7% of stearic acid. The mixed oil contained ${\alpha}$, ${\gamma}$ and ${\delta}$-tocopherols and tocotrienols showing the highest contents of ${\alpha}$-tocopherol. Total amount of tocopherols contained in the mixed oil was 46.63 mg/100 g oil. The composition and content of phytosterols were determined by a GC equipped with a flame ionization detector. Total quantity of phytosterols in the mixed oil was 712.80 mg/100 g oil. The most predominant phytosterol in the mixed oil was ${\beta}$-sitosterol, followed by campesterol and stigmasterol, in a decreasing order. The oxidative stability of the mixed oil was much higher than that of perilla oil, and similar to that of soybean oil, indicating the high oxidative stability of the mixed oil.
