According to food chemistry, the pH of cornstarch is remarkably close to neutral, typically falling between 4.5 and 7.0. This makes cornstarch a non-reactive, neutral ingredient, which is why it is so versatile in cooking and baking. The exact pH can vary slightly depending on the brand and processing method, but it is never strongly acidic or alkaline.

Unlike bacteria and viruses, prions are not living organisms, which explains why they are not destroyed by normal cooking temperatures. These infectious proteins possess an extraordinary resistance to heat and conventional sterilization methods, a critical fact for understanding food safety.

Over 90% of the world's inorganic phosphate supply is sourced from mining rock deposits. Understanding how we get inorganic phosphate is crucial, as it is a finite resource vital for modern agriculture, animal feed, and numerous industrial processes.

The concept of measuring energy in food dates back to the 18th century, with initial experiments linking respiration to combustion. The journey to understand how did humans come up with calories involves a surprising cast of scientists and engineers, and was not a straightforward process, evolving significantly over centuries of scientific inquiry.

Surprisingly, the slow rusting of iron releases heat, a chemical process that mirrors faster combustion. In modern applications, this fundamental property reveals how to harness and utilize what energy does iron produce, including heat and electricity.

Did you know that without food and water, no living thing on Earth could survive? For Class 3 students, understanding why living things need food and water is a fundamental part of science, explaining how plants, animals, and humans grow, get energy, and stay healthy. This article will break down these important concepts into easy-to-understand parts.

As the second most abundant mineral in the human body, constituting about 1% of total body weight, phosphate is a critical component for life. Found in nearly every cell, this essential nutrient is involved in far more than just maintaining bone density, playing a profound and multifaceted role across many biological systems.

Over 500 chemical compounds have been isolated from the cannabis plant, with the precise combination of these elements determining the unique properties of a Sativa strain. This article explores what are the ingredients in sativa and how they work together to create its distinctive effects and characteristics.

Fact: Vitamins and minerals are essential micronutrients, but unlike macronutrients, they provide no kilocalories. Understanding which of the following is a common characteristic of all vitamins and minerals (Quizlet style question) is key to grasping their critical role in nutrition.

While heavy water, or deuterium oxide (D2O), is not radioactive in its pure form, its higher mass compared to regular water (H2O) significantly impacts biological processes. Consuming enough heavy water to replace a significant percentage of your body's normal water is not okay and is lethal to mammals. This difference in mass is enough to interfere with the delicate biochemical reactions essential for life.
