Betaine is a byproduct of sugar beet processing. Betaine works by preventing the build-up of an amino acid called homocysteine.This amino acid can harm blood vessels and contribute to heart disease, stroke, or circulation problems.etaine is not a cure for homocysteinuria. Betaine may also be used for purposes not listed in this medication guide. Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
A smooth muscle is excited by external stimuli, which causes contraction. Each step is further detailed below. Inducing stimuli and factors. Smooth muscle may contract spontaneously (via ionic channel dynamics) or as in the gut special pacemakers cells interstitial cells of Cajal produce rhythmic contractions.
Electrical activitation of smooth muscle is passed from cell to cell by gap junctions. Smooth muscle of the gut can generate intrinsic rhythmic contraction, independent from direct neural control.Input from the autonomic nervous system increases or decreases the level of this spontaneous activity.mooth muscle ((unlike skeletal muscle) consists of individual cells (leiomyocytes), each cell with its own nucleus. The function of smooth muscle also differs substantially from that of striated muscle.
