多肽

So low-dose polymyxin B can be used safely in clinic.

多粘菌素B是一种环状阳离子多肽类抗生素，既有抗菌作用，又能拮抗内毒素活性，但其严重的肝肾毒性限制了临床应用，后来有人发现小剂量的多粘菌素B可保留中和内毒素作用，而无抗菌作用，使用安全，值得在临床上推荐使用。

Parathyroid hormone as one of the most important hormones that could regulate bone metabolism, is synthesized and secreted by the principal cell of parathyroid gland.

甲状旁腺激素是由甲状旁腺主细胞合成和分泌的一种单链多肽激素，是人体内维持血钙恒定的主要激素。

However, these algorithms could produce a significant number of incorrect peptide identifications.

然而这些方法操作时存在大量错误的多肽鉴定。

Key of the peptide after hydrolysis ruptures, turn into polypeptide, molecular volume falls to 2000 ～ 10000, can the water that dissolve unloads at normal temperature.

水解后肽键断裂，变为多肽，分子量降至2000～10000，能溶于常温下的水。

Sequence analysis showed that the BDNF gene of Asiatic Black Bear was highly conserved compared to those of human and giant panda, with an identity of 94.5% and 98.9%, respectively. The deduced amino acid sequence of the mature protein was found to be identical to those of all the reported mammalians. According to gene sequence alignment, the giant panda appeared to be phylogenetically closer to Asiatic Black Bear than the lesser panda.

在推导的多肽序列中，其成熟区氨基酸序列与所有已报道哺乳动物的完全一致；对亚洲黑熊及其相关物种BDNF基因序列的比较分析，发现大熊猫与包括黑熊在内的熊科动物亲缘关系更近，而与小熊猫较远。

Proteins are made up of one or more polypeptides.
