PLEASE HELP! match each of the following characteristics with the correct macromolecule. you may use the macromolecule more than once.

A) subunits are simple sugars
B) has a 1:2:1 ratio is C, H,&O
C) functions as structure of hair&nails
D) elements present are C, H,O, N,&P
E)hemoglobin, insulin, and antibodies are examples
F) functions include energy storage and insulation
G)is held together by peptide bonds
H) subunits are 1 glycerol & 3 fatty acids

1. carbohydrates
2. lipids
3.proteins
4. nucleic acids

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
