The effects of gamma irradiation at medium dose levels on commercial starches (corn starch/CS, sweet potato starch/SS, and potato starch/PS) were investigated in terms of its color and lipid oxidation. The CS, SS, and PS samples were irradiated at 0, 1.5, 3, 4.5 and 6 kGy by a Co-60 gamma irradiator and used for measuring Hunter's colors and TBA value. Irradiation doses applied did not cause apparent changes in Hunter color parameters between the control and irradiated groups. But, the decrease in lightness (L value) for CS and the increase in both redness (a value) for SS and yellowness (b value) for PS were observed, respectively, thereby resulting in slight increase in overall color difference (${\Delta}E$) upon irradiation. Browning intensity observed with the naked eye for gelatinized starches by irradiation doses was also gradually increased along with irradiation dose, which was more remarkable in SS. The thiobarbituric acid (TBA) values of samples showed a dose-dependant increase with ${\geq}0.9964$ of $R^2$ (p<0.05).

Lipids extracted from two garlic samples (Allium sativum Linnaeus) were studied. Total lipid content of the samples ranged from 310 to 342mg/100g of fresh garlic. These lipids were shown to consist of $36.4{\sim}43.5%$ neutral lipids, $20.3{\sim}24.3%$ glycolipids, and $36.2{\sim}39.3%$ phospholipids. Among the neutral lipids, triglycerides were predominant $(80.5{\sim}83.6%)$ with smaller amounts of free sterols, free fatty acids, and sterol esters being present. 1, 2-Diacylglycerol acetates, 1, 3-diacylglycerol acetates and cholesterol acetates were also tentatively identified. Esterified steryl glycosides and steryl glycosides were major sugar-containing lipids, but monogalactosyl diglycerides, cerebrosides, digalactosyl diglycerides and sulfolipids were relatively minor components. Of the phospholipids, phosphatidyl cholines and serines, and phosphatidyl ethanolamines were the major components, comprising over 85% of this class. Phosphatidic acid and phosphatidyl inositols were also present. The major fatty acids in the total and three lipid classes were linoleic, palmitic, oleic and linolenic acid.

The composition of the neutral lipids in the free and bound lipids from four varieties of experimentally cultivated potatoes were identified and quantified by thin layer- and gas-liquid chromatographies. The results were summarized as follows ; 1. The neutral lipids contained in the free and bound lipids were fractionated and identified as esterified sterol, triglyceride, diglyceride, free fatty acid, and free sterol, of which triglyceride and esterified sterol were most abundant. Meanwhile, the triglyceride and esterified sterol contents in the free lipid to the total lipid quantity were 10 and 2.7 % respectively, approximately 3 times higher than the 3.0 and 0.8 % contained in the bound lipid. 2. The fatty acid composition of the neutral lipids in the free and bound lipids was the same as that of the total free and bound lipids. The only difference was that content of saturated fatty acid was lower rate in the neutral lipid of the free lipid than in the total free lipid, whereas the unsaturated fatty acid was more abundant in the neutral lipid of the free lipid. Fatty acid composition of individual neutral lipid was of almost the same pattern as that of the total neutral lipid.

당뇨병 치료 방법은 식사조절, 운동, 교육, 약물치료, 인슐린 주사 등이다. 운동은 당뇨 치료의 기본이다. 성인 당뇨병환자의 대부분인 제 2형 당뇨병에서 운동은 혈당을 낮추며, 체중을 감소시키고, 체내 지방질을 좋아지게 하며, 심장.혈관.신경계 및 망막 합병증을 감소시킨다. 인슐린 주사를 반드시 맞아야 하는 제 1형 당뇨병환자가 운동을 하면 인슐린 주사를 줄이거나 맞지 않을 수 있다.

쌀의 영양성분은 단백질(7%), 지방질(1%), 당질(80%), 조섬유(0.4%), 회분(0.5%)으로 되어 있으며, 인체 내에서 당질은 열량 공급원으로, 조섬유는 식이섬유 공급원의 역할을 한다. 그리고 무기질로는 인, 칼륨, 칼슘, 마그네슘, 나트륨, 철분 등이 포함되어 있다. 벼에는 약 38종의 병해가 발생하는데 생육시기, 재배장소, 기후 등 환경이나 품종에 따라 달리 나타나며 벼 생육중기 이후에 발생하는 주요 병해는 다음과 같다.

식용유지나 지방질을 함유하고 있는 유지식품은 저장 및 가공 중에 산화가 일어나 식품에 바람직하지 않은 결과를 나타낸다. 그러므로 영양학적, 기술적 과정에서 볼 때 저해제 첨가에 의한 산화억제가 바람직하다. 본 논문은 몇가지 지질 시스템과 식품 중에서 차 폴리페놀의 항산화 활성 메카니즘, 항산화제 작용부위 그리고 항산화 물질로서의 가능성에 대해 살펴보았다.

우리 몸에 좋은 닭고기는 섬유질과 염분이 적어 육류 중에서 가장 소화가 잘 되며 또한 지방질은 다른 육류보다 훨씩 불포화 상태여서 콜레스테롤 성분을 적게 섭취해야하는 식이요법에 적합하다. 값도 싸고 요리법도 다양하며 영양분이 풍부한 이들 닭에 찬사를 보내며 리더스 다이제스트 79년 10월호의 잭 덴턴 스코트의 글과 함께 한국의 양계역사를 게재한다.

Structural studies of membrane proteins, importantly involving interpretation of genomics information, many signaling pathway and major drug target for drug discovery, are having difficulty in characterizing the function using conventional solution nmr spectroscopy and x-ray crystallography because phospholipid bilayers hindered fast tumbling and crystallization. Here, we studied the structure of the pf1 coat protein in oriented phospholipid bilayers by home-built solid-state NMR probe. Bacteriophage pf1 was purified from Paeudomonas Aeruginosa and coat protein of bacteriophage pf1 was isolated from DNA and other proteins.

Mucor sp. KCTC 8405P was cultivated in a jar fermentor for the production of fungal lipid containing ${\gamma}-linolenic$ acid with feeding the glucose solution periodically. The transition of the fungal growth into the mycelial phase from yeast-like growth was achieved by pH shift after the first two day of cultivation in the low pH medium and then lipid accumulation was accelerated until the seven day of cultivation, when the glucose in the culture broth was almost consumed. With the culture conditions applied in this experiment, biomass of 99.3 g/l by the dry cell weight and the total extractable lipid of 38.0 g containing 3.5 g/l ${\gamma}-linolenic$ acid were obtained.
