chain 测验

The C-terminal portion of the variegin chain exits the active site, binds at the “prime” subsites and continues along the thrombin surface to exosite I.

Long chain fatty acids consumed daily at these levels for up to 35 d preceding parturition could have had carryover effects interfering with GnRH-induced calcium mobilization in pituitary gonadotropes, thereby affecting LH release, although this remains a speculation at this time.
