I am asked to do the following

Research the functions, classes, examples and uses of: five different protiens, three different carbohydrates, and three different lipids.

I chose

collagen
hemoglobin
keratin
fibrin
Lysozyme (had to be 1 enzyme)

Fructose
Glucose
Lactose

Stearic Acid
Glycerol
Cutin

What do you think they mean by classes??

what is collagen a class of (is this what I am trying to answer), what is the answer because I failed to find it using google.

Thanks

For protein classes, you could group them by functional class, e.g. structural protein, transport protein, enzyme, etc.  There aren't really any formally defined classes for general proteins.  Other systems of classification could be soluble protein v. membrane protein (and within membrane proteins, peripheral, integral, and transmembrane proteins).  For enzymes, there is a formal set of enzyme classifications which divides enzymes into six different categories: hydrolases, ligases, lyases, transferases, isomerases, and oxidoreductases.

For carbohydrates, there are various types of classes such as monosaccharide, disaccharide, oligosaccharide, polysaccharide; reducing sugars v. non-reducing sugars, etc.

For lipids, classes would include groups such as triacylglycerols, steroids, sphingolipids, etc.

Also, I would not consider glycerol a lipid, even though it is a component of some lipids.
