Abstract: Corn (Zea mays), commonly referred to as maize, is one of the most cultivated cereal crops worldwide. This study presents a comprehensive overview of the chemical composition of corn and its various applications in the medical and domestic sectors. Corn is composed of significant macronutrients including carbohydrates, proteins, and fats, along with essential micronutrients such as B-complex vitamins, magnesium, and phosphorus. It is also rich in phytochemicals like lutein, zeaxanthin, and ferulic acid, which contribute to its antioxidant and anti-inflammatory properties. In the medical sector, corn is utilized in the development of nutraceuticals, anti-diabetic formulations, cardiovascular therapies, and as a dietary supplement. Domestically, corn and its derivatives (flour, starch, oil) are employed in cooking, baking, biodegradable household products, and personal care items. This paper integrates chemical insights with practical applications, highlighting corn's role as a sustainable resource in both health care and home management. Further research is recommended to explore advanced therapeutic uses and environmentally friendly domestic innovations.
