Abstract
The invention discloses a teaching aid of an insulin structure model. The teaching aid of the insulin structure model comprises a first bead string, a second bead string and a third bead string, wherein the second bead string and the third bead string are connected with the first bead string through a connecting part respectively; and connecting strings are arranged between the second bead string and the third bead string. The teaching aid of the insulin structure model is simple in structure and is of a detachable structure; and therefore, not only can the structure characteristics of insulin be displayed vividly, but also the memory of a user can be deepened, which is beneficial to teaching.
Description
Technical field
The present invention relates to the teaching aid field, relate in particular to a kind of insulin structure model teaching aid.
Background technology
Insulin (Insulin) is to be subjected to the stimulation of endogenous or exogenous material (as glucose, lactose, ribose, arginine, hyperglycemic factor etc.) and a kind of proteohormone of secreting by pancreas islet B cell.
Insulin can promote picked-up and the utilization of body tissue's cell to glucose, and suppresses decomposition and the gluconeogenesis of glycogen, and therefore, pancreas islet have the effect that reduces blood sugar.Insulin can promote the synthetic of fat and store, and the blood free fatty acid is reduced, and suppresses simultaneously the decomposition oxidation of fat.Insulin deficit can cause fat metabolic disturbance, and depot fat reduces, and decomposes and strengthens, and blood fat raises, and of a specified duration can cause artery sclerosis, and then causes the serious illness of cardiovascular and cerebrovascular; Meanwhile, insulin deficit can cause body fat to decompose reinforcement, generates a large amount of ketoboidies, ketoacidosis occurs.Insulin promotes synthetic to amino acid whose picked-up and protein of cell on the one hand, the decomposition of Profilin matter on the one hand, thereby be conducive to growth.The protein stimulatory matter synthesis of adenohypophysis growth hormone, must have the existence of insulin just can show.Therefore, for growth, insulin is also one of indispensable hormone.Insulin can promote potassium ion and magnesium ion to pass cell membrane to enter in cell; Can promote the synthetic of DNA (deoxyribonucleic acid) (DNA), RNA (ribonucleic acid) (RNA) and atriphos (ATP).
Therefore, the research of insulin is particularly important with utilization.Because insulin belongs to the molecule rank, need to use electron microscope observation, bring inconvenience in teaching field, teacher generally uses picture when explanation insulin, yet picture lacks vividness, can not well cause student's interest, can not effectively deepen student's memory.
