) In adition dl structure. Write toaride,fatty acid, amino acid, or nucleotide) based on 2) In addition, do the following 1) Identify the TYPE of monomers below (monosable provided. answer on the line provided e monosaccharide, circle all of the HYDROXYL functional groups y acid, circle and label the CARBOXYL and METHYL functional groups. ho acid, circle and label the CARBOXYL and AMINO functional groups, and also the b. c. On th On the fatty On the f part of the molecule that is the SIDE (R) GROUP On the nucleotide, circle and label the PHOSPHATE d. GROUP, SUGAR, and NITROGENOUS BASE. A. C. ,H C-C-N H-c-c-c-c-c-c-c-c-c-c-c-c OH CH 2 HO OExplanation / Answer
A. Monosaccharide: Monosaccharide is the monomer of sugar.
B. Nucleotide: contain nitrogenous base, sugar and phosphate
C. Fatty acid: contain a long hydrocarbon chain with carboxyl group
D. Amino acid: contain a carboxyl group and an amino group
2. a. Hydroxyl group is denoted by -OH. Thus in monosaccharide there are 5 hydroxyl (-OH) group.
b. Carboxyl group is denoted by -COOH and methyl group is indicated by -CH3. Thus there is one CH3 group and 1 methyl group is present in fatty acid.
c. In amino acid COOH is carboxyl group and NH2 is amino group, CH2CH2COOH is R.
d. PO4 is phosphate group, Pentacyclic portion with O is sugar and rest portion is nitrogenous base.
2nd page:
1. The molecule at the right side is glucose which is a monomer and glucose is carbohydrate. This is aldose as it contain aldehyde functional group (-CHO)
2. The molecule is triglyceride not phospholipid as phospholipid contain phosphorous (P).
3. The molecule is phospholipid as it contain phosphate group with fatty acid.
