help with biology please?

Question

what are the monomers that comprise: proteins, carbohydrates, lipids

Answer 1

Proteins are made of amino acids.
Carbohydrates are made of monosaccharides, or simple sugar. e.g. Starch is a polymer of glucose
Lipids do not really have monomers, but some of them do have distinct parts. Triglycerides (fat) is made of glycerol and 3 fatty acids, while phospholipids contain glycerol, 2 fatty acids, and a phosphate head, such as choline.

Answer 2

Monomers are the smaller molecules that polymerize to form the polymers -- naturally occuring polymers include proteins, carbohydrates, lipids. So,
Amino acids are combined to form proteins (polypeptides);
sugars (monosaccharides) like glucose to form larger carbohydrates (polysaccharides); and,
glycerides and/or monocoboxylic acids form lipids (triglycerides, Long-chain fatty acids, etc. there are many lipids)

Answer 3

Carbohydrates:
monomers are called Monosaccharides

Proteins:
monomers are called amino acids (20 different kinds that bond to form Polypeptides (protein))

Lipids:
monomers are:
1) Glycerol (3 carbon Chain)
2) Fatty Acid Chain (hydrocarbon (C and H) with a carboxyl group (COOH) attached)

Answer 4

Proteins are made of amino acids.
carbohydrates are made of sugars (monosaccharides).
Lipids are fatty acids, but i'm not sure what they're looking for (i.e. what kind of lipid)
