Question: 1 / 400

Which classification does not fall under hormones?

Sugars

Sugars do not fall under the classification of hormones. Hormones are chemical messengers that are produced by glands in the endocrine system and are responsible for regulating various physiological processes in the body. They can be categorized into different groups based on their structure and origin.

Steroids, for instance, are a category of hormones that are derived from cholesterol and include sex hormones such as testosterone and estrogen. Amino-acid derivatives, such as adrenaline and thyroxine, are hormones derived from single amino acids and play important roles in the body's response to stress and metabolic regulation. Peptides are short chains of amino acids and include hormones like insulin and growth hormone, which regulate various bodily functions.

In contrast, sugars, which are carbohydrates, primarily serve as a source of energy for the body rather than functioning as regulatory hormones. Therefore, sugars do not fit into the classification of hormones, making this choice correct.
