课程名称：维生素概念 课程概述： 本课程将深入探讨维生素的概念。维生素源自拉丁语“vita”，意为“生命”。维生素是食物中有机成分，对生长和维持健康至关重要，且需求量极小。它们是必需的微量营养素，生物体自身无法合成或合成不足，必须通过饮食获取。维生素能够执行特定的生物功能，维持生物体的最佳生长和健康。维生素的发现是人类在健康和疾病认知方面的一大科学成就。1912年，卡西米尔·冯克（Casimir Funk）首次提出了“生命胺”（vital amines）的概念，后来演变为“维生素”（vitamins）。 维生素的分类： 维生素主要分为两类：水溶性维生素和脂溶性维生素。 1. 脂溶性维生素：维生素A、D、E和K属于脂溶性维生素。它们储存在脂肪组织中，因此得名脂溶性维生素。课程还将进一步详细讲解。
The word " vitamin" comes from the Latin word "vita" means "life".Vitamins are organic components in food that are needed in very small amounts from growth and for maintaining good health.Every body must eat a certain amount of vitamins to stay healthy.Vitamins are chemicals found in very small amount in many different kind of foods.A vitamin is an organic molecule that is an essential micronutrient that an organism needs in small quantities for the proper functioning of its metabolism. Essential nutrients cannot be synthesized in the organism, either at all or not in sufficient quantities, and therefore must be obtained through the diet.Vitamins may be regarded as organic compounds required in the diet in small amounts to perform specific biological functions for normal maintenance of optimum growth and health of the organism.The discovery of the vitamins was a major scientific achievement in our understanding of health and disease. In 1912, Casimir Funk originally coined the term "vital amines".Kazimierz Funk, commonly anglicized as Casimir Funk, was a Polish-American biochemist generally credited with being among the first to formulate the concept of vitamins, which he called "vital amines" or "vitamins". Classification of VitaminsVitamins are generally classified as water-soluble vitamins and fat-soluble vitamins.1. Fat-Soluble VitaminsVitamin A, D, E and K are fat-soluble. These are stored in adipose tissues and hence are called fat-soluble vitamins.and many more in explanation.
