Monosaccharides are classified by their number of carbon atoms, and the specific group of monosaccharides with four carbon atoms is known as tetroses. These carbohydrates are fundamental, simple sugars that serve crucial, albeit less recognized, roles within cellular metabolism, unlike the more common six-carbon sugars.

Over two-thirds of the human body's adipose tissue is composed of lipids, or fats. This diverse group of macromolecules is universally characterized by its hydrophobic nature, but its elemental makeup varies depending on the specific lipid class. The most fundamental and common elements in lipids are carbon, hydrogen, and oxygen.

Carbohydrates are the most abundant organic molecules found in nature and play a vital role in all life. Their name itself hints at their core chemical composition, as carbohydrates are primarily composed of three specific elements: carbon, hydrogen, and oxygen.

Every living organism relies on proteins to carry out vital functions, with some containing hundreds of thousands of different types. To understand how these complex molecules work, it is fundamental to know what are the elements of the protein, which consist of common foundational atoms and other, less frequent ones.

Every living cell in the human body relies on four major classes of biological molecules for structure and function. To understand our own biology and nutrition, we must know what kind of molecules are these: carbohydrates, lipids, or proteins, and how they differ from one another.

Proteins are complex macromolecules essential for virtually all life processes, and they are built from a universal set of core elements. This article explores in detail what are the five elements in proteins and explains their vital roles in forming the structures and functions that drive living organisms.

In AP Biology, lipids are a crucial macromolecule category, and a key concept to master is the distinction between saturated and unsaturated fatty acids. While both serve essential functions like energy storage, their chemical structure dramatically influences their physical state, with far-reaching implications for everything from cell membrane fluidity to human health.

Did you know the 'saturated' in a saturated fatty acid chain refers to the maximum number of hydrogen atoms bonded to each carbon, distinguishing it from other fat molecules? These simple, linear hydrocarbon chains are the foundation for its distinct physical and chemical characteristics, making them integral to our understanding of lipids.

Carbohydrates are the most abundant organic molecules in nature, with the term originating from the idea of a "hydrate of carbon". This concept is directly reflected in the general chemical formula which represents a carbohydrate, offering a simple yet profound insight into their elemental composition.
