蛇毒是毒蛇修饰唾液腺的液体分泌物。 蛇依靠毒液来禁用猎物并帮助消化过程。 蛇毒的主要成分是蛋白质。 这些毒性蛋白是蛇毒大部分有害作用的原因。 它还含有酶,有助于加速破坏大分子之间化学键的化学反应。 这些酶有助于碳水化合物,蛋白质,磷脂和核苷酸在猎物中的分解。 有毒的酶还可以降低血压,破坏红血球,并抑制肌肉控制。 蛇毒的另一个组分是多肽毒素。 多肽是氨基酸链,由50个或更少的氨基酸组成。 多肽毒素破坏导致细胞死亡的细胞功能。 蛇毒的一些有毒成分在所有有毒蛇种中都有发现,而其他成分仅在特定物种中发现。

新西兰奥克兰大学生物学Essay代写:蛇毒如何工作?

Snake venom is the fluid secretions from the modified salivary glands of venomous snakes. Snakes rely on venom to disable prey and aid in the digestive process. The primary component of snake venom is protein. These toxic proteins are the cause of most of the harmful effects of snake venom. It also contains enzymes, which help to speed up chemical reactions that break chemical bonds between large molecules. These enzymes aid in the breakdown of carbohydrates, proteins, phospholipids, and nucleotides in prey. Toxic enzymes also function to lower blood pressure, destroy red blood cells, and inhibit muscle control. An additional component of snake venom is polypeptide toxin. Polypeptides are chains of amino acids, consisting of 50 or fewer amino acids. Polypeptide toxins disrupt cell functions leading to cell death. Some toxic components of snake venom are found in all poisonous snake species, while other components are found only in specific species.
