Steroids

Are they part of the study design? It's not explicitly stated but most of my resources seem to cover them. Would it be encompassed under the general term of "lipids"?

Its good to know and understand a bit about steroid hormone especially when you study about homeostasis and metabolism

Yeap. its good to know their chemical properties and their functions (typically ligands except for cholesterol). You also need to know the difference between steroid hormone signal transduction and protein hormone signal transduction. Its no big deal if you dont know what signal transduction is yet, but when u study it sometime in april/may, just remember my advice.

I was mainly asking as it *briefly* came across in Chapter 1 of Nature of Biology under Lipids. If it gets covered in more detail later on, I'll be sure to take note.

For AOS 1, you'll need to know that they're a type of lipid (and so are hydrophobic), and the role of cholesterol in maintaining plasma membrane fluidity.

For AOS 2, you'll need to know about the properties of steroid hormones and be able to compare them to those of peptide and amino acid-derived hormones (eg. receptors for steroid hormones are found within the cytoplasm, whereas receptors for peptide hormones are found on the surface of the cell membrane). You'll also have to be able to explain why steroid and peptide hormones have these different properties.
