D. Function:1. Most Carbs are readily available sources of energy
Energy is stored in the bonds between Carbon AtomsIt is released by the breaking of bonds between monosaccharide through a process called HYDROLYSISbreaking apart by adding water
Once broken down into monosaccharides they are dismantled by Respiration
HYDROLYSIS

of plants and the exoskeleton of insects

Steroids: have the same shape as cholesterol but generally serve as hormones in the body
Androgen: aka. male hormone responsible for development of male primary and secondary sexual characteristics and tissue building
Female Sex hormones: Responsible for the development of primary and secondary sexual characteristics and regulation of menstruation
Modern birth control pills (YAZ) introduce synthetic progesterone to trick the body into thinking it is pregnant. Progesterone prevents further ovulation during pregnancy

4. Proteinsa. Made up of Carbon, Hydrogen, Oxygen, and Nitrogenb. Structure
Monomers are Amino Acids
All Amino Acids have the same Amino group (NH3)+
Amino means Nitrogen
and Carboxyl group(COO)
This makes it an acid
The RGroup is for the rest of the molecule...There are 20 different R groups......meaning there are 20 different amino acids
