偶数链饱和和不饱和脂肪酸主要存在于自然界的许多动植物脂肪和油中。
直到最近，人们一直认为天然脂肪中很少出现直链奇数脂肪酸。最近，分析仪器证明这是一个谬误，因为奇数碳脂肪酸的存在已被证明是几乎所有天然脂肪中的次要成分。它们在自然界中究竟扮演了什么样的角色，最终可能会通过持续的研究来确定。
Nu Chek高纯度脂质是在我们自己的实验室中从好的商业动植物油源中分离出来的。奇数化合物的脂肪酸链通常通过扩链合成。饱和链和不饱和系列（多不饱和脂肪除外）总是通过在100理论板高真空分馏塔上的最终蒸馏来纯化。这样做是为了去除颜色和其他无关的微量杂质。只有那些即使GLC和TLC超载过大也无法检测到杂质的部分才可用于产品销售。
高纯度化合物（甚至饱和系列）的分离始终在惰性气体（即N2）的气氛下进行保护。除高熔点饱和化合物外，最终产品始终用氮气冲洗，在真空下密封在Pyrex玻璃安瓿中，并在-30°C或更低的低温条件下储存，直至准备装运。
只要有可能，我们的纯脂肪酸和酯就可以通过各种物理技术从天然来源中分离出来，将不需要的异构体转化到可忽略的最小程度。
Even numbered chains of saturated and unsaturated fatty acids occur predominately in many of nature's animal and vegetable fats and oils.
Until recently it was assumed that the occurrence of straight chain odd number fatty acids in natural fat were rare. Recently analytical instrumentation has proven this to be a fallacy, since the presence of odd number carbon fatty acids have been shown to occur as minor constituents in practically every natural fat. What role they actually play in nature's scheme may be eventually established by continued research.
Nu-Chek high purity lipids are isolated in our own laboratory from the best commercial animal or vegetable oil source available. Fatty acid chains of odd numbered compounds are generally synthesized by chain extension. Saturated chains and the unsaturated series (other than polyunsaturated fats) are always purified by a final distillation on a hundred theoretical plate high vacuum fraction column. This is done to remove color along with other extraneous trace impurities. Only those fractions on which impurities are unable to be detected even with large overloads both by GLC and TLC are made available for product sale.
The Isolation of high purity compounds (even the saturated series) are always protected under an atmosphere of inert gas (i.e. N2). The final product, with the exception of high melting saturated compounds, is always flushed with nitrogen, sealed in Pyrex glass ampules under vacuum, and stored under cold conditions of -30°C or lower until ready for shipment.
Whenever possible, our pure fatty acids and esters are isolated from their natural source by various physical techniques holding the conversion of unwanted Isomers to a negligible minimum.
