Why Water Is Essential for Life

Lecture no. 2 from the course: Biochemistry and Molecular Biology: How Life Works

Why Water Is Essential for Life

Taught by Professor Kevin Ahern | 30 min | Categories: The Great Courses Plus Online Science Course

Investigate why water is so singularly suited to life. Composed of two hydrogen atoms for each oxygen atom, water molecules have a polar charge due to the uneven arrangement of shared electrons. See how this simple feature allows water to dissolve sugars and salts, while leaving oils and fats untouched. Also learn what makes water solutions acidic or basic, and how this property is measured on the pH scale.
