Three organic compounds containing nitrogen have been isolated fTom soft coral Sarcophyton Molle Collected from South China Sea. Their structures have been determined by UV, IR, MS, 1H NMR and 13C NMR as sinumeramide Thymine and Thympidine.

从中国南海软珊瑚中分离到三个含氮化合物，其结构经紫外光谱、红外光谱、质谱和核磁共振（1HNMR、13CNMR）分析分别确定为神经酰胺Sinumeramide，胸腺嘧啶和脱氧尿核嘧啶苷。

Resembles thymine, but easily interconverts to tautomeric form that pairs with guanine.

与胸腺嘧啶相似，但很容易转换成与鸟嘌呤配对的互变异构形式。

In the dehydrogenating process,the anionic A-T fragmentgradually changes its electronic configuration fromπ~* toσ~* state,like the singlebases adenine and thymine.

在脱氢过程中，阴离子A-T的碎片会逐渐改变它的低能电子组态，从π~*态转变到σ~*态，这种变化跟在单个碱基腺嘌呤和胸腺嘧啶的情况相似。

"Thymine: Organic compound of the pyrimidine family, often called a Base, consisting of a ring containing Both nitrogen and carbon atoms, and a methyl group."

胸腺嘧啶：一种嘧啶类有机化合物，通常叫做基底，由含有氮和碳原子以及甲基的环形物组成。

This causes the watson, Krick to think immediately between 4 kind of basic groups has 22 corresponding the relations, has formed the gland fat ling and the thymine pair, the bird fat ling and the cytosine pair concept.

这使沃森、克里克立即想到4种碱基之间存在着两两对应的关系，形成了腺膘呤与胸腺嘧啶配对、鸟膘呤与胞嘧啶配对的概念。

Double helix model significance, not only means that has verified the DNA member structure, it also has prompted more importantly the DNA duplication mechanism: As a result of the gland fat ling always with the thymine pair, the bird fat ling always with the cytosine pair, this explained that two chain's basic group orders are each other supplementary, so long as had determined a chain's basic group order, another chain's basic group order also determined.

双螺旋模型的意义，不仅意味着探明了DNA分子的结构，更重要的是它还提示了DNA的复制机制：由于腺膘呤总是与胸腺嘧啶配对、鸟膘呤总是与胞嘧啶配对，这说明两条链的碱基顺序是彼此互补的，只要确定了其中一条链的碱基顺序，另一条链的碱基顺序也就确定了。

American biochemists found out, the main element of nucleic acid bases are gland fat methotrexate, the birds fat methotrexate, thymine, cytosine.
